Merge rust-bitcoin/rust-bitcoin#1740: create a set of recognized denomination forms
82b6332b91 create a set of recognized denomination forms (yancy)

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.

Martin Habovstiak ed80df5ebc Add `ChainHash::from_genesis_block_hash`
This improves readability of converting `BlockHash` into `ChainHash`.
It's useful in e.g. Electrum protocol which sends `BlockHash`
(serialized backward).

Closes #1751

Mutate mul_u64 with mutagen
Add the `mutate` attribute to mutate `mul_u64`. Add non-doc comments
listing the two false positives. These are identical but we list them
twice so when devs grep for `mutagen false pos` the same number of lines
for each function is displayed as is displayed by the `mutagen` run.
This coding false positives thing is also introduced in PR #1655.

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.

Merge rust-bitcoin/rust-bitcoin#1707: Add a method to `pow::Target` for returning difficulty as an f64.
2158f88f1d Add a method to `pow::Target` for returning difficulty as an f64. (junderw)

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.

38ed9bdf49 MOVE ONLY: Move TapTree to taproot module (sanket1729)

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.

Merge rust-bitcoin/rust-bitcoin#1682: Include address in Error::NetworkValidation
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.

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.

Pull request description:

  Currently we implement string parsing for height/time from the `absolute` module but not the `relative` module.

  Improve the macros used to implement string parsing and use the new versions to implement string parsing for the height and time types in `relative`.

  Done while reviewing data structures in relation to `serde`.

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".

Split Sighash into LegacySighash and SegwitV0Sighash
Currently we have `TapSighash` that is used for taproot sighashes but
for non-taproot sighashes we use `hash_types::Sighash`. We can improve
the API by creating a `LegacySighash`, and `SegwitV0Sighash`.

Copy the original `Sighash` macro calls to create the two new types in
the `sighash` module.

While we are at it, put the `TapSighash` and `TapSighashTag` into the
`sighash` module also.

Move sighash to crypto module
There is never any use for the `sighash` module unless one is signing,
which requires the `crypto` module. The `sighash` module should
therefore live in the `crypto` module. This is not an API breaking
change because we reexport it at the crate root.

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.

Pull request description:

  Implement `AsRef<[u8; X]>` for hash types including wrapped hash types. Doing so means at times the compiler can no longer infer the type because we have `AsRef<[u8]` implemented also but we can use `into_inner` and `as_inner` to get the inner array if needed.

  This touches code that will likely be changed by #1577 and when we do #1491 but I believe its a step forward.

ae2aaaa436 Add `script_pubkey_lens` method (Martin Habovstiak)
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.

Martin Habovstiak 6be89bf94f Add `minimal_non_dust` to `TxOut`
In some scenarios it's useful to create outputs with minimal relayable
value. E.g. outputs designated for fee bumping using CPFP. A method for
this is useful.

This implements a constructor of `TxOut` that computes the minimal
non-dust value from the passed script.

Closes #1459

Martin Habovstiak cf068d16b0 Implement transaction weight prediction
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.

  I re-did the whole PR manually because of the recent `script` module changes. I hope no one else has to do that - if you do please feel free to holla and I'll "rebase" your PR for you.

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.

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.

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.
