dirstate: remove the python-side whitelist of allowed matchers This whitelist is too permissive because it allows matchers that contain disallowed ones deep inside, for example through `intersectionmatcher`. It is also too restrictive because it doesn't pass through some of the matchers we support, such as `patternmatcher`. It's also unnecessary because unsupported matchers raise `FallbackError` and we fall back anyway. Making this change makes more of the tests use rust code path, and therefore subtly change behavior. For example, rust status in largefiles repos seems to have strange behavior.

match: make `was_tampered_with` work recursively This is useful if we are to use it outside of Rust, when deciding whether or not to do some fast-path operation with a given matcher.

largefiles: mark more matchers as having been tampered with These happened to slip through the cracks earlier because they weren't caught by tests. Now that we're enabling rust fast path more widely these start breaking.

branching: merge stable into default

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 In case we do get a dirstate error, we want to get the full error message and not just an opaque `Dirstate error`.

dirstate-v2: check that root nodes are at the root before writing More explanations in the previous changeset.

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.

admin-verify: fix error message handling `dirstate.verify` used to return tuples but does not anymore, it returns the pre-formatted error message, which is a nicer interface anyway.

admin-verify: pass p1 down to the dirstate function This was forgotten and can break with certain kinds of corruption.

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.

fold-or-prune-me: update proposal This does the same things but with a narrower wrapping.

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.

hgrc: search XDG_CONFIG_HOME on mac Searching for hgrc was special cased not to look through ~/.config/hg on Mac, but that’s unnecessary: Macs support it as do other unix based systems. There are plenty tools that use it there, e.g. git, and people expect it to work, e.g. "https://stackoverflow.com/questions/72499837/mercurial-on-macos-doesnt-read-config-hg-hgrc". Initial code introduced in 354020079723.

base-revsets: use an author that actually exercises a lot of changesets This was caught in my big find-and-replace: d4ba4d51f85f. The point of `base-revsets` is to give revsets that will give a good coverage of the repository. Using Pierre-Yves as the second largest committer (in terms of number of changesets) seems like a good idea.

match: simplify the rust-side file pattern kind parsing There's no need to add the ':' characters if we're simply pattern matching against constants next.

match: share code between includematcher and patternmatcher No need to have this duplication.

matchers: support patternmatcher in rust
