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.

Note: this commit is intentionally unformatted to make diff easier to

It wasn't obvious that displaying address with alternate formatting
upper cases bech32 addresses.
This change adds information about this and also a note about the
compatibility of various wallets.
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:
It was a little tricky to bump the version number because of https://github.com/rust-bitcoin/rust-bitcoin/issues/1553. There are a couple other things I considered trying, which maybe we'll do for future releases, but I believe this works for now.
Maybe should wait for #1111.

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.

Enable formatting in CI by doing:
- Add a section to the `test.sh` scripts to run the formatter (guarded by
the env variable `DO_FMT`) for all crates (bitcoin, hashes, internals).
- Add `DO_FMT` to the nightly `Tests` CI job.
Various formatting issues have crept into the codebase because we do not
run the formatter in CI.
In preparation for enabling formatting checks in CI run `cargo +nightly
fmt` to fix current formatting issues. No changes other than those
create by the formatter.
Because we have rust-secp in the loop, we need to update rust-secp, push
a new tag, and use that here, to ensure that the direct dependency on
bitcoin_hashes, and the rust-secp version, are compatible.

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

42b07586ac Improve the public API (Tobin C. Harding)
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`

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.
