py3: fix for Python 3.12 emitting SyntaxWarning on invalid escape sequences
Mercurial became very noisy after https://github.com/python/cpython/commit/
a60ddd31be7ff96a8189e7483bf1eb2071d2bddf ,
for example:
$ python3.12 mercurial/store.py
mercurial/store.py:406: SyntaxWarning: invalid escape sequence '\.'
EXCLUDED = re.compile(b'.*undo\.[^/]+\.(nd?|i)$')
This verbosity made some tests fail.
The problems were mostly insufficiently escaped regexps, relying on the Python
parser/scanner preserving invalid escape sequences.
cext: fix for PyLong refactoring in CPython 3.12

histedit: fix diff colors
The problem here is that indexing a bytestring gives you integers, not
chars, so the comparison to b'+' ends up being wrong.
We don't really have a way to test curses output, so no tests to
verify the correctness of this behaviour.
dirstate: fix a potential traceback when in `copy` and `rename`
Before this changes, calling `hg copy` or `hg rename` could trigger a traceback
about using an invalidated dirstate. This wasn't caught by the test as it needed
the blackbox extension to preload the dirstate first in a way "refresh"
invalidates it.
Changing the context creation patterns fixes it.
dirstate: fix the bug in [status] dealing with committed&ignored directories
In particular, these directories can "infect" their sibling directories with
ignored status due to using a shared memoization cell by accident.
This fixes bug #6795.
rust: remove out-of-date comment
We've migrated to a newer version of Rust, so it doesn't make sense anymore.
rust: upgrade `rayon` dependency
This includes a potential soundness fix as well as some improvements to
performance which should be helpful.
