exchange: fix locking to actually be scoped
The previous code was taking locks before entering with statements, so
exception before the with statement would not release the lock (except for
garbage collection).

rust-status: sort the failed matches when printing them
This was making the tests flaky after the recent patch¹ that opened up
more of the code to the Rust-augmented status.

chistedit: change action for the correct item
We have an experimental config histedit.later-commits-first from c820866c52f9,
and when it's true, the order of commits in histedit UI is reversed, both in
text mode and in curses mode.
But before this patch key presses in curses mode would change histedit actions
in the same old order, i.e. trying to edit the latest commit (which would be
first now) would put "edit" action on the last commit in the list. This wasn't
a cosmetic issue, histedit would actually proceed to edit the first commit in
the list.
Let's map rules to display items (hopefully now correctly).

rust: blanket implementation of Graph for Graph references
The need comes from the fact that `AncestorsIterator` and many
Graph-related algorithms take ownership of the `Graph` they work with.
This, in turn is due to them needing to accept the `Index` instances
that are provided by the Python layers (that neither rhg nor `RHGitaly`
use, of course): the fact that nowadays the Python layer holds an object
that is itself implemented in Rust does not change the core problem that
they cannot be tracked by the borrow checker.
Even though it looks like cloning `Changelog` would be cheap, it seems
hard to guarantee that on the long run. The object is already too rich
for us to be comfortable with it, when using references is the most
natural and guaranteed way of proceeding.
The added test seems a bit superfleous, but it will act as a reminder
that this feature is really useful until something in the Mercurial code
base actually uses it.

rust-cpython: don't swallow the dirstate error message

dirstate-v2: add check of parent/child nodes being related when writing
This stems from a corruption seen in a private repository. We're not sure
of the source of the corruption, and it's very possible that we're seeing
compounded effects of multiple writes on a corrupted dirstate.
Adding this check is not expensive in itself and large writes of the dirstate
are not common.
This change does not catch this problem at the root node, the next one will.

admin-verify: expect a number of errors to be returned
It's the responsibility of the check to handle errors, we only care about
the total count to sum up the check's work.
We use `admin::verify -c dirstate` to test this path at least somewhat.

re2: make errors quiet
By default, the re2 library will output error on its own instead of keeping the
error in an exception. This make re2 printing spurious error before fallback to
the stdlib remodule that may accept the pattern or also fails to parse it and
raise a proper error that will be handled by Mercurial.
So we also pass an Option object that changes this default.

subrepo: propagate non-default path on outgoing
There was already a fix made in 5dbff89cf107 for pull and push commands. I did
the same for the outgoing command.
The problem I identified is that when the parent repository has multiple paths,
the outgoing command was not respecting the parent path used and was always
using the default path for subrepositories.

wireprotoserver: ensure that output stream gets flushed on exception
Previously flush was happening due to Python finalizer being run on
`BufferedWriter`. With upgrade to Python 3.11 this started randomly
failing.
My guess is that the finalizer on the raw `FileIO` object may
be running before the finalizer of `BufferedWriter` has a chance to run.
At any rate, since we're not relying on finalizers in the happy case
we should also not rely on them in case of exception.

match: strengthen visit_children_set invariant, Recursive means "all files"
My previous interpretation of "Recursive" was too relaxed: I thought it
instructed the caller to do something like this:
> you can stop calling `visit_children_set` because you'll need to descend into
> every directory recursively, but you should still check every file if it
> matches or not
Whereas the real instruction seems to be:
> I guarantee that everything in this subtree matches, you can stop
> querying the matcher for all files and dirs altogether.
The evidence to support this:
- the test actually passes with the stronger invariant, revealing no
exceptions from this rule
- the implementation of `visit_children_set` for `DifferenceMatcher`
clearly relies on this requirement, so it must hold for that not to
lead to bugs.

match: fix the rust-side bug in visit_children_set for rootfilesin matchers
The fix is checked by `test_pattern_matcher_visit_children_set` test,
which is what caught the bug in the first place, but also by an end-to-end
test that I made for this purpose.
Accept the new results of Cargo tests
Many of these were already annotated with "FIXME", which is a good sign.

tests: add tests and document expectations from visit_children_set in rust
The tests this patch are adding have the form of formal spec in
invariants::visit_children_set::holds,
and then a series of checks that all examples must satisfy this
formal spec.
I tried to make the spec consistent with how this function is used
and how it was originally conceived. This is in conflict with how it's
documented in Rust. Some of the implementations also fail to implement
this spec, which leads to bugs, in particular when complicated patterns
are used with `hg status`.
