Rename taproot::Error to SigFromSliceError
This error type is only used in the `from_slice` function. Use prefix
`Sig` because `taproot::FromSliceError` does not fully express how the
error came about.

Use specific identifier for the error, this aids usage but also prevents
us later adding "random" other variants into this error and using it in
other functions.

Remove explicit error conversion
We provide a `From<secp255k1::Error>` impl so we do not need to
explicitly convert the error return, just use `?`.

Merge rust-bitcoin/rust-bitcoin#1873: Improve `hashes::Error`
06afd52a12 Improve hashes::Error (Tobin C. Harding)

Pull request description:

  We are trying to make error types stable on the way to v1.0

  The current `hashes::Error` is a "general" enum error type with a single variant, better to use a struct and make the error usecase specific.

  Improve the `hashes::Error` by doing:

  - Make it a struct
  - Rename to `FromSliceError`
  - Move it to the crate root (remove `error` module)

  Includes usage in `bitcoin`.

Pull request description:

  The `ScriptBuf` type can be serialized using it's `to_bytes` function. Do not use the `psbt::Serialize` trait to do so in test code.

Martin Habovstiak 6fec1789b9 Fix associated constants of `InputWeightPrediction`
These constants had an error that they had `script_size` set to 0 which
was incorrect because it's not length of the script but serialized size.
Rather than just bumping the value this uses the `from_slice` method
which is less error-prone.

This also deletes a useless test of the constants.

Pull request description:

  Numbers with only zeros after decimal points are valid if they are also

  artificially disallowed as "too precise" which was at least misleading.

  This change allows parsing such numbers.

  And yes, I know this is not perfectly efficient (unless the compiler figures out some magic opts) but so isn't the rest of the code. TBH this parsing code drives me crazy and I'd love to rewrite it to be more efficient and readable.

Merge rust-bitcoin/rust-bitcoin#1820: Expose valid (min, max) difficulty transition thresholds
8e6f953aa7 Expose valid (min, max) difficulty transition thresholds (Wilmer Paulino)

Pull request description:

  Once `U256` was made private, we lost the ability to check whether a valid difficulty transition was made in the chain, since `Target` doesn't expose any operations. We only choose to expose `Shl<u32>` and `Shr<u32>` such that we can compute the min and max target thresholds allowed for a difficulty transition.

  This is something we realized was missing after bumping to `rust-bitcoin v0.30.0` in `rust-lightning`, specifically for our `lightning-block-sync` crate. It may also be worth having a helper in `rust-bitcoin` that checks a header properly builds upon the previous, but that can be left for future work.

Merge rust-bitcoin/rust-bitcoin#1793: Comment predict_weight
dff757d7db Comment predict_weight (yancy)

Pull request description:

  I've been reading over the `predict_weight` function since it is one of the biggest challenges for coin-selection.  IE choosing inputs and constructing an optimal selection strategy requires predicting the weight to get the best selection.  It's great this work has been done but there are some things I don't understand well enough to comment.

  1) why are we looking at the size of VarInt struct here
  > let script_size = script_len + VarInt(script_len as u64).len()

  2) [predict_weight_internal](36500b4451/bitcoin/src/blockdata/transaction.rs (L1245)) has a bunch of magic numbers.  I'd like to be able to comment this as well but I don't fully understand that function.

  Also, `Transaction.rs` is a big file and it seems like all of the prediction stuff could be moved to a separate module or maybe a separate crate?

Pull request description:

  Please note, whether or not we need a per-file license comment is out of scope for this PR. This PR leaves us with the most simple per-file solution possible and leaves the merit of per-file license comment to be discussed on another day.

  Simplify the per-file license stuff by doing:

  - Remove the attribution line from each file.

      Currently we have a mishmash of attribution lines accompanying the SPDX identifier. These lines are basically meaningless because:

      - The date is often wrong
      - The original author attributed is not the only contributor to a file
      - The term "rust bitcoin developers" is basically just noise

  - Introduce SPDX license identifiers into `hashes` and remove attribution line (ie, make `hashes` uniform with `bitcoin`)

  Required before merge please:

  - [x] ack from apoelstra because as the library original author many of the changes in this PR remove his name
  - [x] ack from Kixunil because he had some concerns in the issue descussion

bitcoin: Remove attribution from all files
Currently we have a mishmash of attribution lines accompanying the SPDX
identifier. These lines are basically meaningless because:

- The date is often wrong
- The original author attributed is not the only contributor to a file
- The term "rust bitcoin developers" is basically just noise

Just remove all the attribution lines and be done with it. While we are
at it add an SPDX line to the few files missing it, whether this license
nonsense is even needed is left as an argument for another day.

095b7958dd Make `sha256t_hash_newtype!` evocative of the output. (Martin Habovstiak)

Pull request description:

  The Rust API guidelines state that macros should be evocative of the
  output, which is a sensible recommendation. We already had this for
  `hash_newtype!` macro but didn't for sha256t version.

  This changes the macro to have this syntax:

  ```rust
  sha256t_hash_newtype! {
      // Order of these structs is fixed.
      /// Optional documentation details here. Summary is auto-generated.
      /*pub*/ struct Tag = raw(MIDSTATE_BYTES, LEN);

      /// Documentation here
      #[hash_newtype(forward)] // optional, default is backward
      /*pub*/ struct HashType(/* attributes allowed here */ _);
  }
  ```

  Closes https://github.com/rust-bitcoin/rust-bitcoin/issues/1427

  Depends on #1769

  How do you like the syntax? Is weird `struct Foo = bar(..);` acceptable?

This commit refactors the Address struct and its methods to improve
its functionality and usability.The AddressInner struct now holds
the payload and network, and the PhantomData<V> type is used to track
the network validation state.

Also as_unchecked and assume_checked_red methods are added to allow
conversion between checked and unchecked network validation state.

Pull request description:

  I took a stab at restricting the acceptable forms here.  There was some consensus that "BtC" was confusing that was discussed in a previous pr https://github.com/rust-bitcoin/rust-bitcoin/pull/1715.

  Also, personally I felt that the `PossiblyConfusingDenomination` enum variant was itself confusing.  I think it's probably cleaner to just maintain a list of acceptable forms and treat everything else as unknown.  For now I just created a const of possibly confusing forms.

Pull request description:

  One final push crew, 16 patches, only a few are big.

  All non-trivial formatting is done in separate patches so the changes can be verified mechanically.

  With this applied the whole `rust-bitcoin` crate will be formatted.

  Big thanks to everyone for putting up with the ongoing formatting PRs, no-one likes doing these but hopefully this an improvement to the project - especially in helping us get more contributors to the project.

Make test panic instead of using code comment
Currently we have a code comment that is supposed to assist devs in
maintaining the `network::constants::Network` type by failing to build
if a new variant is added. This plays havoc with the formatter because
the comment is hanging at the bottom of a match block and the formatting
thinks its for the proceeding line of code.

Instead of using a code comment add a panic so the unit test fails if a
new variant is added to `network::constants::Network`.

00b46d6d9d Indent functions (Martin Habovstiak)
d56d202aeb Support weight prediction in `const` context (Martin Habovstiak)

Pull request description:

  **Notes for reviewers:**
  This is something that I want to use in my code and hopefully reasonably easy to review, so if this can get into 0.30 that'd be really nice. No hard feelings if it doesn't.
  I tried to put extra effort into making review easier by:
  * intentionally "mis-formatting" the first commit so diff is smaller and easy to understand - see individual commits.
  * copying patterns from non-const fn to const fn so it's obviously correct (includes same variable names)
  * not bothering with the array trick in `VarInt::len` and simply accepting the limitation of Rust 1.46+ (I use 1.48 BTW).

  **Description**

  Some smart contracts or simplified wallets statically know the sizes of
  transactions or inputs. The possible approaches to handling them so far
  were re-computing the values (and hoping the optimizer will const fold
  them) or using a simple constant which may be harder to understand and
  get right. It's much nicer to just use a `const` but our code didn't
  support it until now.

  This change adds methods that can compute the prediction in `const`
  context for Rust versions >= 1.46.0 which allow use of loops (and
  conditions but those could be workaround anyway).

  As a side effect of this, the change also adds `const` to `VarInt::len`
  in Rust 1.46+. While this one could be made unconditional using array
  trick it's probably not worth it because of the planned MSRV bump.

Pull request description:

  Closes #1703

  This adds a conversion function to U256 to get an f64. We use the method shown in the following blog post.

  https://blog.m-ou.se/floats/

  Target::MAX was converted to a f64 and set as a const that is verified in a unit test.

  The code is rather confusing, so I took a crack at explaining it in my comments as well. Please let me know if you want it cleaned up some more.

Pull request description:

  There are several common spends in Bitcoin that have known input weight predictions. It can be useful to have these as constants, so this change adds them. However, this only adds native segwit ones as the others are slowly fading away and might clutter the API.

  If anyone wants other constants, please write them for me, their value is not that great to me so I'm not motivated to figure out the correct numbers. :)

  This would be nice to add to 0.30 since it's small and easy but not critical.

Pull request description:

  This PR changes/removes the serde implementation for the following types

  - TaprootSpendInfo: Removed. This data structure contains derived information for taproot spending that cannot be validated easily. To elaborate, `TaprootSpendInfo` is constructed from a tree, but loses information about the tree structure and maintains handy information like `script_control_block_map`, cached tweaked key, Merkle root etc.
  - TaprootBuillder: Removed. Hard to implement and not very useful.
  - TapTree: Modified to check invariants.
  - NodeInfo: Now implements serde with support for Hidden nodes
  - ScriptLeaf: Removed serde. Users should not directly construct this. This is just an output iterator item of `TapTree::script_leaves()`

  Data structure changes:

  - Introduced `LeafNode`: Supports Hidden leaves. Has serde implemented
  - Cleanly separate `TapTree` and `NodeInfo`:  `TapTree` is a full BIP370 compatible tree with no hidden nodes. `NodeInfo` is a tree that can potentially contain hidden leaves.
  - Added `NodeInfo::leaf_nodes`: Iterator that iterates over known and hidden leaves of `NodeInfo`.
  - Updated `TapTree::script_leaves`: Iterator that is guaranteed to output known leaves.

73e876ffd4 Include address in Error::NetworkValidation (Subhradeep Chakraborty)

Pull request description:

  Fixes: #1677

  ## Change
  In `bitcoin/src/address.rs`, a new field `address` is added to the enum variant `Error::NetworkValidation`. Also, the implementation of `Display` trait for `Error` is updated to print the `address` field.

  However, to print the `address` through `Display`, either the reference is needed or `Address` and `Payload` both need to derive the `Copy` trait. Since I am little new to both the rust-bitcoin codebase and rust itself, I am confused about choosing between the two and have moved with the first one. Would appreciate any feedback on this.

Pull request description:

  We created the `crypto` crate as a container for cryptography modules with the idea that it may be split out into a separate crate. There is no reason for users of the lib to know about this module. Also, we have two `taproot` modules, one in `crypto` and one at the crate root, this makes for un-ergonomic usage of the lib.

  Improve the public API by doing:

  - Make the `crypto` module private (`pub(crate)`).
  - Re-export `crypto::taproot::Signature` (and `Error`) from `crate::taproot`

with the idea that it may be split out into a separate crate. There is
no reason for users of the lib to know about this module. Also, we have
two `taproot` modules, one in `crypto` and one at the crate root, this
makes for un-ergonomic usage of the lib.

Improve the public API by doing:

- Make the `crypto` module private (`pub(crate)`).
- Re-export `crypto::taproot::Signature` (and `Error`) from
  `crate::taproot`

161273b209 Re-name hash inner/byte methods (Tobin C. Harding)
324b6f264b Use `into` for hash argument (Tobin C. Harding)

Pull request description:

  Currently we have an associated type on hash types `Inner` with accompanying methods `into_inner`, `from_inner`, `as_inner`. Also, we provide a way to create new wrapped hash types. The use of 'inner' becomes ambiguous with the addition of wrapped types because the inner could be the inner hash type or the `Inner` byte array of the inner wrapped hash type.

  In an effort to make the API more clear and uniform do the following:

  - Rename `Inner` -> `Bytes`
  - Rename `*_inner` -> `*_byte_array`
  - Rename the inner hash to/from methods to `*_raw_hash`

  Correct method prefix `into_` -> `to_` because theses methods convert owned `Copy` types.

  Add the trait Bound `Copy` to the `Bytes` type because we rely on this trait bound for the conversion methods to be correctly named according to convention.

  Because of the dependency hole created by `secp256k1` this patch changes the secp dependency to a git tag dependency that includes changes to the hashes calls required so that we can get green lights on CI in this repo.

Rename schnorr module to taproot
"schnorr" is a dirty word; the current `schnorr` module defines a
`Signature` that includes a sighash type, this sighash type is a bitcoin
specific construct related to taproot. Therefore the `Signature` is
better named `taproot::Signature`. Note also that the usage of `schnorr`
in `secp256k1` is probably justified because the
`secp256::schnorr::Signature` is just doing the crypto.

While we are at it, update docs and error messages to use "taproot"
instead of "schnorr". Also change function names and identifiers that
use "schnorr".

Martin Habovstiak 8fedbcbf13 Add `ecdsa::SerializedSignature`
`Signature` only supported serialization into `Vec` which required a
heap allocation as well as prevented statically proving maximum length.

Adding a specialized type that holds a byte array and size solves this.
The solution is very similar to `secp256k1::ecdsa::SerializedSignature`.
The difference is that serialized signature in this crate contains
sighash bytes flag while in `secp256k1` it doesn't.

Martin Habovstiak bb2c7ec790 Introduce `hex_lit` crate
So far we deserialized hex into `Vec<u8>` at run time. This was mainly
in tests where it had negligible performance cost. However moving the
computation to compile time has a few benefits: it allows proving the
length of the decoded bytes and identifies potential typos before the
code goes through LLVM and other compilation machinery which makes
feedback faster.

This change uses the `hex_lit` crate to move computation to compile
time. It is implemented as `const` declarative macro which doesn't blow
up compilation time.

pow: Remove Mul/Div by arbitrary integer types
When we added `Target` and `Work` types we implemented multiplication
and division by anything `Into<u64>`, this is not typically done in the
Rust stdlib and also is semantically incorrect for the types.

Remove `Mul` and `Div` impls from `Target` and `Work`. Also remove
`Mul<T>` for `T: Into<u64>` from the private `U256` type.

Pull request description:

  We recently created a `types` subdirectory under `script` to keep all the `Script` and `ScriptBuf` impls together. Turns out this additional level of subdirectory is a bit annoying and we can achieve the same grouping by just using `script/mod.rs`.

cf068d16b0 Implement transaction weight prediction (Martin Habovstiak)

Pull request description:

  When creating a transaction one must know the the fee beforehand to set
  appropriate amounts for outputs and to know the fee, weight is required.
  So far we only had a method on an already-constructed transaction. This
  method clearly wasn't helpful when constructing the transaction except
  for hacks like temporarily adding an all-zeroes signature.

  This change adds a function that can compute the transaction weight
  without knowing individual bytes of the scripts, witnesses and other
  elements. It only needs to know their sizes.

  To make the API less error-prone a special, trivial, type is also added
  for computing the lengths of witnesses.

  There are many more changes in the pipeline for all this read/write "script int" stuff. This PR was done ages ago and I believe it stall adds value.

Merge rust-bitcoin/rust-bitcoin#1600: Refactor script module
a9108d3939 Refactor script module (Tobin C. Harding)

Pull request description:

  The `script` module is large and unwieldy.

  Refactor the `script` module, splitting it up into a tree of modules. Here are a few of the changes and their stated benefits

  - Split the two script types out into separate files: Readers of the methods can then tell immediately from the file name which type they are reading.
  - Put all the impls for the two script types together: Makes parsing the API easier because one can more quickly see which traits are implemented on what i.e., all the `AsRef` imlps are grouped together.
  - Put the impls for the two script types in order, first `Script` then `ScriptBuf`: Makes it easier for us to see if we missed something.
  - Put the `Builder` and `Instruction` (and associated) types in their own modules: Some devs find long files hard to navigate, so far there hasn't been too much push back against short files.
  - Put tests in a separate file: This idea was recently discussed.

  This is only moving code and fixing import statements etc. No other changes to the code.

  ## Note to reviewers

  This PR is impossible to review from the diff because it moves so much code. Perhaps better to look at the resulting `src/blockdata/script/` directory and see if you like it.

  #### Motivation

  While adding script tagging I was having difficulty navigating the script module.

- Put all the impls for the two script types together: Makes parsing the
API easier because one can more quickly see which traits are implemented
on what i.e., all the `AsRef` imlps are grouped together.
- Put the impls for the two script types in order, first `Script` then
`ScriptBuf`: Makes it easier for us to see if we missed something.
- Put the `Builder` and `Instruction` (and associated) types in their
own modules: Some devs find long files hard to navigate, so far there
hasn't been too much push back against short files.
- Put tests in a separate file: This idea was recently discussed.

This is only moving code and fixing import statements etc. No other
changes to the code.

Rename from_slice methods to decode
The `TaprootMerkleBranch` and `ControlBlock` both have methods on them
called `from_slice` but these methods do more that just basic copy from
a slice. `decode` is a more descriptive name.

Deprecate the `from_slice` methods and implement `decode`, on other
changes to the logic.

Martin Habovstiak 7c6854fe02 Use `Borrow` instead of `Deref` in `SighashCache`
The requirement for a type dereferencing to `Transaction` prevented
storing the cache in long-lived data without resorting to silly
wrappers. Since `Borrow` is implemented both for `T` and for smart
pointers it's a more flexible bound which this change implements.

While this is technically breaking, all usual non-generic code will
continue to work beause smart pointers generally have `Borrow`
implemented.

Pull request description:

  This work started out, as the branch name suggests, as an effort to use the `hex_lit` crate. But once I got to this stage it seems that the `hex!` macro we have provides different, useful, functionality than the `hex_lit::hex!` macro (it allows usage with non-consts). So I'm unsure if we want to remove it now.

  - Patches 1 - 6 are preparatory clean ups
  - Patch 7 reduces usage of  `FromHex`, please see git log for full description
  - Patch 8 removes `hex_from_slice` and fixes a bug in how we display `Sighash`

Remove hex_from_slice and display Sighash forwards
`Sighash` should be displayed forwards according to BIP143. Currently we
are displaying it backwards (as we do for double SHA256). This is
working because parse using `Vec::from_hex`.

We have the means to parse hex strings directly for hashes, we no longer
need `hex_from_slice`.

BIP143 test vectors display double SHA256 forwards but we display
backwards, this is acceptable because there is no fixed display in the
ecosystem for double SHA256 hashes. In order to overcome this we parse
test vector hex strings with into `Vec` when needed.
