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`.
No idea why this re-export is here, the `Prevouts` type is not even used
in the `psbt` module.
Remove the re-export of `crate::sighash::Prevouts` from `pstb`.
013dffa65d tests: Use script hash methods (Tobin C. Harding)
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.
No logic changes, since the impl of `psbt::Serialize` for `ScriptBuf` just calls `to_bytes`.

b03c24db8c Add a checked version of weight mul fee_rate (yancy)
Pull request description:
Add a checked version of fee_rate * weight. While I like the trait version of just being able to multiply `feerate * weight`, it's not really very useful imo since a large input feerate could cause an overflow. Instead of changing the trait in https://github.com/rust-bitcoin/rust-bitcoin/pull/1849 (not idiomatic enough I guess) I added a `checked_weight_mul` method to `FeeRate`.

Pull request description:
During the last round of releases (bitcoin 0.30, hashes 0.12) we removed the `FromHex` implementation from all types except vecs and arrays. We added `FromStr` impls for types that roundtrip with `Display`.

We have methods to convert a script to a `WScritpHash` and `ScriptHash`,
no need to do this manually, let alone use the `psbt::Serialize` trait
to do so.

Pull request description:
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

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.

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.

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?

The readme has gotten a bit messy with various contributors using
different collum width. Make it all 100 so that new contributors have

c4c64c0dc5 Test with minimal dependency versions (Martin Habovstiak)
d5655d503a Bump core2 dependency from 0.3.0 -> 0.3.2 (Tobin C. Harding)
Pull request description:
This is work originally done by Kixunil in #1272, I picked it up to help out. The only changes I made were rebasingg, updating the recent lock file, adding `--locked` to hashes contrib file, and adding a co-developed-by tag for accountability.
It could happen that we unknowingly depend on a new version of a crate without updating `Cargo.toml`. This could cause resolution issues for downstream users. It's also unclear for outsiders to know with which dependencies did we test the crate.
This change commits two lock files: `minimal` and `recent`. `minimal` contains minimal dependency versions, while `recent` contains dependency versions at the time of making the change.
Further, this adds CI jobs to test with both lock files, CI job for `internals` crate, removes old `serde` pinning and prints a warning if `recent` is no longer up to date. (We may have to override it somehow if any crate breaks MSRV.)
The documentation is also updated accordingly.

Our previous MSRV did not support MIN/MAX associated consts so we had
methods min/max_value. Now that our MSRV is Rust 1.48.0 we can use the
consts.
Deprecate min/max_value methods in favor of MIN/MAX associated conts.
We currently use the functions `min_value` and `max_value` because the
consts were not available in Rust 1.41.1, however we recently bumped the
MSRV so we can use the consts now.
