rust-regex: fix issues with regex anchoring and performance
It turns out that the way I tried to work around `regex`'s behavior difference
with `re2` and Python's `re` was 1) buggy and 2) much more complicated than
needed.
In a few words:
`regex` adds `.*` on either side of patterns when no start or end anchor is
present. My previous workaround put `^` or `$` for every pattern, which is
wrong even without the other 2 bugs on top of it.
Using `^(?:<patterns>)` right at the end of the `regex` path fixes the issue.
I've opened an issue to get a build option instead:

diff: avoid going from contexts to nodes and back
This will allow us to pass in-memory contexts that may not have a
valid node to the diffing logic.

setup: raise minimum Python version to 2.7.4
On older Python versions, Mercurial is not really usable because of
https://bugs.python.org/issue10211.
Recently someone reported a crash on the mailing list when running Mercurial
on Python 2.7.3. There was consensus that fixing compatibility for a Python
version more than 7 years old is not worth it. So, instead of making Mercurial
crash with an obscure exception, this patch raises the minimum Python version
to 2.7.4.

fsmonitor: coerce `clock` variable to byte-string (issue6321)
Callers of `fsmonitor.state.setlastclock` pass their arguments
wrapped in `pycompat.sysbytes` to ensure the value is a `bytes`
on Python 3. However in `fsmonitor.poststatus.__call__`, if the
return value of `getlastclock()` is `None`, we use the value of
`fsmonitor.poststatus._startclock` instead, which is not converted
to a byte string in the same manner. This commit converts the
value of `startclock` to a byte string using `pycompat.sysbytes`
in the constructor for `poststatus`, to avoid the "`str` + `bytes`"
error from issue 6321.

py3: change default priority and length used for sorting hooks to be compatible with python 3
The call to `sorted(hooks.values())` can on line 213 of hooks.py can raise when using
python 3. For instance, when hooks.values is `[(0, 2, b'post-commit.check-status', b''),
(None, None, b'changegroup.app-hooks', <object object at 0x7f5279885590>)]`, the error is
`TypeError: '<' not supported between instances of 'NoneType' and 'int'`
This fix keeps the same order that was used in python 2 without relying on comparison with
None.

dirstate: make sure the dirstate is loaded before the changelog (issue6303)
Before this change, it was possible for the changelog to be loaded before the
dirstate. If a transaction happens betwen the changelog and dirstate reading,
the dirstate can up end poitning toward a revision not existing in the (olded)
changelog. This lead to a warning.
With this revision, we preload the dirstate parent before reading the changelog.
This has a negligible performance impact on performance for all case we are
tracking.

rust-dirstatemap: don't read the dirstate when requesting parents
A future patch for issue 6303 reveals a big performance regression in the Rust
`DirstateMap` that reads the entire dirstate when requesting parents instead
of the first 40 bytes.
`perfdiscovery` gets a *significant* speedup (from 0.101 to 0.016) when applied
against said patch.
I'm assuming it has other performance benefits, but this is already a good
enough win.

Specifically, when `changes` is:
[(b'@upstream-committed', None, <function ui.status>, b'updating bookmark @upstream-committed\n'),
(b'@upstream-committed', binary-node, <function ui.warn>, b'divergent bookmark @ stored as @upstream-committed\n')]
sorting the list raises:
TypeError: '<' not supported between instances of 'bytes' and 'NoneType'
