dirstate-v2: skip evaluation of hgignore regex on cached directories
By making the computation of [has_ignored_ancestor] lazy we're eliding
its computation in the common case when none of its descendants have
changed on disk.
On a ~400k files repo, with a cached status, we saw a ~64% reduction
in CPU time, resulting in a speedup of ~10-15% (on ZFS), and a speedup
of ~38% of XFS (XFS has faster stat operations for some reason).

releasenotes: use re.MULTILINE mode when checking admonitions
Release note admonitions must start at the beginning of a line within
the changeset description:
.. admonitions::
The checkadmonitions function search for and validates admonitions.
Unfortunately, since the ctx.description is multi-line, the regex search
always fails unless the admonition is on the first line.
This changeset adds re.MULTILINE to the re.compile to make the re opbject
multi-line.

windows: gracefully handle when the username cannot be determined
This assumes implementation details, but I don't see any other way than to check
the environment variables ourselves (which would miss out on any future
enhancements that Python may make). This was originally reported as
https://foss.heptapod.net/mercurial/tortoisehg/thg/-/issues/5835.

rhg: parallellize computation of [unsure_is_modified]
[unsure_is_modified] is called for every file for which we can't
determine its status based on its size and mtime alone.
In particular, this happens if the mtime of the file changes
without its contents changing.
Parallellizing this improves performance significantly when
we have many of these files.
Here's an example run (on a repo with ~400k files after dropping FS caches)
```
before:
real 0m53.901s
user 0m27.806s
sys 0m31.325s
after:
real 0m32.017s
user 0m34.277s
sys 1m26.250s
```
Another example run (a different FS):
```
before:
real 3m28.479s
user 0m31.800s
sys 0m25.324s
after:
real 0m29.751s
user 0m41.814s
sys 1m15.387s
```

rhg: enable in case ui.statuscopies=True
rhg already has code to support ui.statuscopies, but it's disabled,
for seemingly no good reason.
