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.

Add `rustfmt::skip` attribute in a couple of places and then remove the
exclude for the `blockdata` module. Do not run the formatter, that will
be done as a separate patch to aid review.
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`.
In preparation for running the formatter introduce a couple of local
variables to reduce the line length and inhibit function call from being
split over multiple lines.
Refactor only, no logic changes.
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.

It wasn't obvious that displaying address with alternate formatting

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

3eb648df01 Add constants to `InputWeightPrediction` (Martin Habovstiak)
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.

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.

Implementing this for spendinfo is really complicated because it
contains some cached data without retaining the components that are used
to compute them.
Users should serde the 1) NodeInfo and 2) internal key and reconstruct
TaprootSpendInfo from it.
This was incorrect and not needed. Users should not be able to create
only tree leaves directly without going through the tree construction in
rust-bitcoin

invariants for several data structures

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.

This change makes it look exactly like the resulting struct, `$len`
parameter was removed since it's not needed, reversing is controlled
using an attribute. The macro is also better documented and ready to be
extended in the future.
The tagged SHA256 newtype is not yet modified because it has a more
complicated input parameters.

It may not be obvious why the condition in `push_bytes` module checks
for negation of 16 and 32 bit architectures rather than 64 bit. This
adds a comment about it being conservative.

"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".
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.
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.
`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.
Script parsing is composed of several functions which implicitly rely on
various properties. Adding a type that restricts the valid values makes
local review easier.
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.
a121e19e94 hashes: Implement AsRef for fixed size arrays (Tobin C. Harding)
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.
Fix: #1462
## Note
This touches code that will likely be changed by #1577 and when we do #1491 but I believe its a step forward.

Woops, somehow I managed to get what was patch 1 of this series merged yesterday, I thought I left it out. Anyways, this is just the remove unused error variant now. No changes to that patch from previous versions of the PR.

dd316e4d14 pow: Remove Mul/Div by arbitrary integer types (Tobin C. Harding)
Pull request description:

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

272cdbcf7c Flatten the types directory (Tobin C. Harding)
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`.
Move code from `types/mod.rs` to `script/mod.rs`, move the two submodules up a level, remove the `types` directory.

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.
Based on #1627
