6e5bd473a6 Improve siphash's `as_u64` -> `to_u64` rename (Martin Habovstiak)
1a91492204 Clean up the siphash mess (Martin Habovstiak)
Pull request description:
Never break SSOT. Never break SSOT. Never break SSOT. Never break SSOT. Never break SSOT. Never break SSOT. Never break SSOT. ...
Previously we had removed `Default` impl on `siphash24::HashEngine` by
reimplementing the type manually. This was a really bad idea as it
inevitably led to API differences that broke the build which we didn't
notice because of unrelated bug. It should've just split the macro from
the start as was suggested but it was claimed to be difficult, I don't
think was the case as can be seen by this PR.
This commit does what the previous one should've done: it renames the
macro to have `_no_default` suffix, creates another one of the original
name that calls into `_no_default` one and moves anything related to
`Default`. This cleanly ensures all previous hashes stay the same while
siphash gets `Default` removed. This also removes all now-conflicting
impls from `siphash24` module which makes the module almost identical to
what it looked like before the change. The only differences are removed
`Default`/`new`, fixes in tests and recent rename of `as_u64` to
`to_u64`.
FTR both of our recent bugs were caused by breaking SSOT. It confirms again my life experience that breaking it will almost certainly bite one in the ass. If there is the most important principle in programming it's quite likely this one.
I was trying to be more "friendly" towards contributors breaking it but I no longer feel that this is a good choice, especially for complicated PRs. Thus I plan to be more aggressive here and NACK pretty much all breaks of SSOT that aren't provably unsolvable.

96e0e720fd feat(bip158): compute canonical filter hash (Rob N)
Pull request description:
From [BIP-157](https://github.com/bitcoin/bips/blob/master/bip-0157.mediawiki#filter-headers)
> The canonical hash of a block filter is the double-SHA256 of the serialized filter.
If a user forgets the "double" in double-SHA256 they will be computing a nonsensical filter hash when this is easily handled by the API.

The previous change was just a dumb rename with no deprecation and it
also kept the `self` type which should be taken by value since the hash
is `Copy`. This improves on it by adding a deprecated method of the
original name and changing the type to be `self` instead of `&self`.

Apparently the `checkout` action will just grab random shit in the case
that you configure it with an unknown key. There is a warning in the
middle of the CI output so ok, I guess there's that.
This commit does not change the pinned version of
rust-bitcoin-maintainer-tools, though we do want to update the pin,
because I want to make sure that the pin is actually working.
This should have been done when we introduced the `primitives`
crate - epic fail.
Intentionally put it before `fuzz` because of the known bug in the CI
script where nothing after `fuzz` gets tested.
Currently the `serde` feature requires an allocator, this is a hang over
from code being written for the `bitcoin` crate.
This was not found because we are not testing `primitives` correctly in
CI (there is the `fuzz` bug and also `primitives` is not even in the
CRATES list).

39f7dcb816 Reduce API surface of tagged wrapped hash types (Tobin C. Harding)
Pull request description:
Recently we made it so that wrapper types created with `hash_newtype` were not general purpose hash types i.e., one could not easily hash arbitrary data into them. We would like to do the same for tagged wrapped hash types.
In `hashes` do:
- Create a new macro `sha256_tag` that does just the tag/engine stuff out of the `sha256t_hash_newtype` macro.
- Deprecate the `sha256t_hash_newtype` macro.
In `bitcoin` do:
- Use a combination of `sha256_tag` and `hash_newtype` to create tagged wrapped hash types.
Note that we do not add private helper functions `engine` and `from_engine` to the tagged wrapper types as we do for legacy/segwit in `sighash`. Can be done later if wanted/needed.

In recent work making functions on hash types inherent it seems we
missed `siphash`. Add inherent getters/setters to the `siphash::Hash`
type and call through to them from the `Hash` trait impl.
Note:
- The `extra_test.sh` script runs for all toolchains.
- The `schemars` crate does not use the repo lock files.
- We need to pin some deps when building the `schemars` test.
Pin in the `extra_test.sh` script, and mention it in the docs so the
docs don't go stale next MSRV update.
This was previously unnoticed because of the `run_task` bug.

7d5ce89dad Fix type ambiguity in IO tests (Martin Habovstiak)
Pull request description:
Conditional compilation depending on Rust version using `cfg` had the disadvantage that we had to write the same code multiple times, compile it multiple times, execute it multiple times, update it multiple times... Apart from obvious maintenance issues the build script wasn't generating the list of allowed `cfg`s so those had to be maintained manually in `Cargo.toml`. This was fixable by printing an appropriate line but it's best to do it together with the other changes.
Because we cannot export `cfg` flags from a crate to different crates we take a completely different approach: we define a macro called `rust_version` that takes a very naturally looking condition such as `if >= 1.70 {}`. This macro is auto-generated so that it produces different results based on the compiler version - it either expands to first block or the second block (after `else`).
This way, the other crates can simply call the macro when needed.
Unfortunately some minimal maintenance is still needed: to update the max version number when a newer version is used. (Note that code will still work with higher versions, it only limits which conditions can be used in downstream code.) This can be automated with the pin update script or we could just put the pin file into the `internals` directory and read the value from there. Not automating isn't terrible either since anyone adding a cfg with higher version will see a nice error about unknown version of Rust and can update it manually.
Because this changes syntax to a more naturally looking version number, as a side effect the `cond_const` macro could be also updated to use the new macro under the hood, providing much nicer experience - it is no longer needed to provide human-readable version of the version string to put in the note about `const`ness requiring a newer version. As such the note is now always there using a single source of truth.
It's also a great moment to introduce this change right now since there's currently no conditional compilation used in `bitcoin` crate making the changes minimal. However it is not yet added to `bitcoin-io` since `bitcoin-io` is not depending on `internals`. It might be a reason to start depending on it but that's for later discussion.

Add a private type that allows us to mutate the inner vector of a
`ScriptBuf` only using public functions and never touching the inner
field.
Done in preparation for moving the `ScriptBuf` to `primitives`.
Mad hackery by Kix!
In preparation for adding script buf extension make the
`push_slice_no_opt` have the same scope as the other private functions,
this will be the scope of the private extension trait.
In preparation for adding a private extension trait change the scope to
`pub(crate)` because the more specific `pub(in ...)` is not currently
supported by our `define_extension_trait` macro.
In preparation for moving the `ScriptBuf` as a plain old datatype to
`primitives`; separate the POD methods into their own impl block.
Refactor only, no logic changes.
