Our embedded crate includes instructions to source a shell script that
sets the `RUSTFLAGS` env var. Having the env var set like this in ones
environment breaks linkage when trying to do "regular" builds.
Document how to clean up.
We never enable the `DO_ALLOC_TESTS` variable, and hence never test the
"alloc" feature in `hashes`.
Remove the `DO_ALLOC_TESTS` variable and add "alloc" to the `FEATURES`
array.
Add a `ValidationError` to the `block` module and remove the two
variants out of `crate::Error`.
This error is only used by the `validate_pow` function, a specific error
better serves our purposes.
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`.

c2f33f60b8 Add changelo entry for removal of FromHex (Tobin C. Harding)
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 never added a changelog mention to either `bitcoin` or `hashes`, lets retroactively add an entry.

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.

6cec19f6d3 Update documentation of `InputWeightPrediction` (Martin Habovstiak)
6fec1789b9 Fix associated constants of `InputWeightPrediction` (Martin Habovstiak)
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
which is less error-prone.

Pull request description:
Numbers with only zeros after decimal points are valid if they are also

artificially disallowed as "too precise" which was at least misleading.
This change allows parsing such numbers.
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.

A new version of rust nightly is causing a test failure for external crates that are not documented. This is currently causing a failure on my branch here: https://github.com/rust-bitcoin/rust-bitcoin/pull/1838

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?

Pull request description:
With the new rewrite of Address, `serde::Serialize` is only implemented on `Address<bitcoin::address::NetworkChecked>` and `Address<bitcoin::address::NetworkUnchecked>`. But the compiler has no way of knowing that that are all the possible versions of `Address`, so the generic `Address<impl bitcoin::address::NetworkValidation>` doesn't implement `serde::Serialize`.

The readme has gotten a bit messy with various contributors using
different collum width. Make it all 100 so that new contributors have
some chance of keeping it tidy.
On top of that, use "natural" line breaks if it assists reading/editing
i.e., don't be dogmatic about column length.
