Throughout the codebase we cast values to `u64` when constructing a
`VarInt`. We can make the code marginally cleaner by adding `From<T>`
impls for all unsigned integer types less than or equal to 64 bits.
Also allows us to (possibly unnecessarily) comment the cast in a single
place.
The `ThirtyTwoByteHash` trait is defined in `secp256k1` and used in
`hashes` as well as `bitcoin`. This means that we must use the same
version of `hashes` in both `bitcoin` and `secp256k1`. This makes doing
release difficult.
Remove usage of `ThirtyTwoByteHash` and use `Message::from_slice`.
Include TODO above each usage because as soon as we release the new
version of secp we can use the new `Message::from_digest`.
This is step backwards as far as type safety goes and it makes the code
more ugly as well because it uses `expect` but thems the breaks.
4300cf2210 Add p2wpkh and p2wsh signature hash functions (Tobin C. Harding)
Pull request description:
The word "segwit" refers to segwit v0 and taproot but these functions are version specific. Add `v0` into the function names.
This is similar to #1994, both based on recent post of mine to bitcoin dev mailing list.

Pull request description:
Add a base weight const to TxIn. I also used this const in strippedsize() and scaledsize(). As a different PR, I think strippedsize and scaledsize could return Weight instead of usize. Also added a small commit to re-arrange commit messages.

The word "segwit" refers to segwit v0 and taproot but currently we have
`segwit_signature_hash` that is version specific (segwit v0).
- Rename `segwit_encode_signing_data_to` to
`segwit_v0_encode_signing_data_to`
- Add `p2wpkh_signature_hash` and `p2wsh_signature_hash` functions
We keep the single encode function because the error handling is better
that way.
While we are at it test the bip-143 test vectors against all the
sighash types of wrapped p2wsh.

f00e93bdcd Fix typos in rustdoc (Tobin C. Harding)
f3412325ea weight: Make docs uniform and terse (Tobin C. Harding)
Pull request description:
- Patch 1 is docs cleanup
- Patch 2 adds two functions to `FeeRate`
From the commit log of patch 2:
Calculating the absolute fee from a fee rate can currently be achieved
by creating a `Weight` object and using
`FeeRate::checked_mul_by_weight`. This is kind of hard to discover, we
can add two public convenience functions that make discovery of the
functionality easier.
Add two functions for calculating the absolute fee by multiplying by
weight units (`Weight`) and virtual bytes (by first converting to weight
units).
This seems like an obvious thing so I'm inclined to think that Kixunil left it out for a reason. (Mentioning you here Kix so even if this merges you'll see it in notifications later on.)

Pull request description:
EDIT: The commit hashes below are stale but the text is valid still.
In an effort to "perfect" our error handling, overhaul the error handling in the `crypto` module.
The aim is to do a small chunk so we can bikeshed on it then I can apply the learnings to the rest of the codebase.
Its all pretty trivial except:
- commit `4c180277 Put NonStandardSighashTypeError inside ecdsa::Error variant`
- comimt `5a196535 Add InvalidSighashTypeError`
- commit `05772ade Use defensive documentation`
Particularly the last one might be incorrect/controversial.
Also, please take the time to check the overall state of error code in the `crypto` module on this branch in case there is anything else we want to do.
Thanks

Improve the script hash types by doing:
- Define the types in the `crypto::script` module
- Put the From impls directly below the type definitions
Keep the current crate level re-export so this does not impact the
public API _if_ people are using the re-export but is still a breaking
change.
Improve the pubkey hash types by doing:
- Define the types in the `crypto::key` module
- Add From<&PublicKey> impl for `PubkeyHash`

The `ServiceFlags` type is used by the p2p layer. It can live in the
`mod.rs` file of the `p2p` module. Done in preparation for removing the
`p2p::constants` module.
This is a straight code move, the `ServiceFlags` replaces the
current re-export.
The `PROTOCOL_VERSION` const is a p2p layer constant. It can live in the
`mod.rs` file of the `p2p` module.
This is a straight code move, the `PROTOCOL_VERSION` replaces the

The `network` module deals with data types and logic related to
internetworking bitcoind nodes, this is commonly referred to as the p2p
layer.
Rename the `network` module to `p2p` and fix all the paths.
Only commit in the docs and error messages to what we _really_ know.
In an attempt to reduce the likelyhood of the code going stale only
commit to what is guaranteed - that we have an error from a module.
This does arguably reduce the amount of context around the error.
As we do for `NonStandardSighashErrorType` add an error struct for
invalid sighash type, used by the `taproot` module instead of returning
a generic error enum with loads of unused variants.
Error types conventionally include `Error` as a suffix.
Rename `NonStandardSighashType` to `NonStandardSighashTypeError`.
While we are at it make the inner type private to the crate, there is no
need to leak the inner values type.
