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.

As part of an ongoing effort to make our error types stable and useful
add a stand set of derives to all error types in the library.
`#[derive(Debug, Clone, PartialEq, Eq)]`
Add `Copy` if possible and the error type does not include
`#[non_exhaustive]`.
If an error type includes `io::Error` it only gets `#[derive(Debug)]`.

This type was defined in the `transaction` module because it was
originally used in a function that had been deprecated in favour of
moving the logic to the `sighash` module.
We just removed the deprecated code so we can now move this type to the
`sighash` module where it is used.
We only keep deprecated code around for one release so we can now remove
code deprecated in v0.30.0
Done in preparation as we gear up for v0.31.0 release.
RawNetworkMessage keep the payload_len and its checksum in the struct, thus
is not needed to serialize the inner network message
pub in fields of both RawNetworkMessage and CheckedData are removed so that
invariant are preserved.
provide accessor method and new for downstream libs.
This is done in order to more easily change the struct without impacting
downstream and also in order to add another field while preserving struct
invariant in future commit.
We have just released the `hex-conservative` crate, we can now use it.
Do the following:
- Depend on `hex-conservative` in `bitcoin` and `hashes`
- Re-export `hex-conservative` as `hex` from both crate roots.
- Remove all the old hex code from `hashes`
- Fix all the import statements (makes up the bulk of the lines changed

Pull all the code that depends on `bitcoinconsensus` out into a separate
module `consensus::validation`.
Leave transaction testing of bitcoinconsensus code in the transaction
module.
There is not need to return the general `script::Error` from the
transaction verify functions. We can better describe the error path by
returning a custom error.
There is no need no nest the `bitcoinconsensus::Error` type within the
`script::Error`, it is the only error type returned by the verify
functions so just return it directly.
In order to keep the embedded and schemacs test crates building when we
update their local transient dependencies we need to use a `patch`
section.
- For `bitcoin/embedded` add `patch` section for `internals`, `hashes`
already has an entry.
- For `hashes/embedded` add `patch` section for `internals`.
- For `hashes/extendend_tests/schemars` add `patch` section for
`internals`.
FTR for direct local dependencies we use a `path` field when specifying
the dependency.
We use two different methods for specifying local dependencies, `patch`
and also `path`. There does not seem to be a reason why we use both,
lets be uniform. Elect to use `patch` for all local crates.

Add rustdocs to `WitnessProgram` commenting on why we carry the witness
version number around with the witness program. This is mainly a dev
comment but it helps document the invariants so make it a rustdoc
comment.
From BIP 141:
> A scriptPubKey (or redeemScript as defined in BIP16/P2SH) that
> consists of a 1-byte push opcode (for 0 to 16) followed by a data push
> between 2 and 40 bytes gets a new special meaning. The value of the
> first push is called the "version byte". The following byte vector
> pushed is called the "witness program".
`WitnessVersion` and `WitnessProgram` are scriptPubkey concerns and
scriptPubkey is basically synonymous with address so in one way it makes
sense that these types are in `address` however we are in the process of
overhauling the `Address` (and `AddressInner`) types so lets move the
witness stuff to `script` and put it in individual sub-modules.
This move helps simplify the address error type also.
Note please, there are a bunch of formatting changes in here in the
error type that I cannot explain and could not remove.

This implements basic facilities to conditionally carry string inputs in
parse errors. This includes:
* `InputString` type that may carry the input and format it
* `parse_error_type!` macro creating a special type for parse errors
* `impl_parse` implementing parsing for various types as well as its
`serde`-supporting alternative
The `as_script_map` is a getter not a conversion function (to/into/as),
as such it should not include the prefix `as_`.
Deprecate `as_script_map` in favour of `script_map`.
This error type is only used in the `from_slice` function. Use prefix
`Sig` because `taproot::FromSliceError` does not fully express how the
error came about.
Use specific identifier for the error, this aids usage but also prevents
us later adding "random" other variants into this error and using it in
other functions.

Our embedded crate includes instructions to source a shell script that

environment breaks linkage when trying to do "regular" builds.
Document how to clean up.
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:
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`.

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.
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.
Fix: #1747
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.
This also deletes a useless test of the constants.

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?

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.

Pull request description:
Please note, whether or not we need a per-file license comment is out of scope for this PR. This PR leaves us with the most simple per-file solution possible and leaves the merit of per-file license comment to be discussed on another day.
Simplify the per-file license stuff by doing:
- Remove the attribution line from each file.
Currently we have a mishmash of attribution lines accompanying the SPDX identifier. These lines are basically meaningless because:
- The date is often wrong
- The original author attributed is not the only contributor to a file
- The term "rust bitcoin developers" is basically just noise
- Introduce SPDX license identifiers into `hashes` and remove attribution line (ie, make `hashes` uniform with `bitcoin`)
Required before merge please:
- [x] ack from apoelstra because as the library original author many of the changes in this PR remove his name
- [x] ack from Kixunil because he had some concerns in the issue descussion
