rhg: add `config.rhg` helptext
This will make using `rhg` more user-friendly and features more
discoverable.

rust-status: query fs traversal metadata lazily
Currently, any time the status algorithm needs to read a directory from the
filesystem (because the stat-only optimization is not available), it also
stats each directory entry eagerly.
Stat'ing the entries is only needed in a few cases (like when checking
the mtime of a directory for caching): this patch creates a wrapper struct
`DirEntry` that only stats the directory entry it represents when needed.
Excerpt of an `strace` before this change on Mozilla Central:
```
openat(AT_FDCWD, ".", O_RDONLY|O_NONBLOCK|O_CLOEXEC|O_DIRECTORY) = 3
newfstatat(3, "", {st_mode=S_IFDIR|0755, st_size=3540, ...}, AT_EMPTY_PATH) = 0
getdents64(3, 0x55dc970bd440 /* 139 entries */, 32768) = 5072
statx(3, ".hg", AT_STATX_SYNC_AS_STAT|AT_SYMLINK_NOFOLLOW, STATX_ALL, {stx_mask=STATX_ALL|STATX_MNT_ID, stx_attributes=0, stx_mode=S_IFDIR|0755, stx_size=772, ...}) = 0
[... 135 other successful `statx` calls]
getdents64(3, 0x55dc970bd440 /* 0 entries */, 32768) = 0
close(3) = 0
```
After this change:
```
openat(AT_FDCWD, ".", O_RDONLY|O_NONBLOCK|O_CLOEXEC|O_DIRECTORY) = 3
newfstatat(3, "", {st_mode=S_IFDIR|0755, st_size=3540, ...}, AT_EMPTY_PATH) = 0
getdents64(3, 0x561567c10190 /* 139 entries */, 32768) = 5072
getdents64(3, 0x561567c10190 /* 0 entries */, 32768) = 0
close(3) = 0
```

rust-status: make `DirEntry` attributes clearer

perf-unbundle: do a quick and dirty fix to make it run on more commit
Without this change, the perf commands fails within the
f67741e8264b::18415fc918a1 range (boundary excluded).
Check inline comment for details.
With this fix, the command is able to run on this range, with a slightly
different behavior (as no revset is "uninlined"). However this is still much
better than not being able to run anything in this range. Especially because
that range do see some performance regression for unbundle.

rhg: fallback when encountering ellipsis revisions
Ellipsis revisions are still experimental and buggy in non-trivial
histories. We currently have no plans to improve this situation nor
to add support for ellipsis revisions in `rhg`.
Falling back should be done carefully (since we may have already done
some work that is visible to the user), but in this case it's highly
unlikely that we're doing anything useful with a repo with ellipsis
revisions, so this should be strictly better, also since the
error message is more explicit.

dirstate-v2: hash the source of the ignore patterns as well
Fixes the test introduced in the last changeset. This caused the hash
to change, which means that the check in the test had to be adapted.
Since this hash is only done as a caching mechanism, invalidation does
not pose any backwards compatibility issues.

dirstate-v2: add test that shows a collision in ignore patterns hash
This hash is used for optimizing dirstate `status`. We demonstrate that the
hash is incorrectly ignoring the changes to the semantics of the ignore
files just because the contents (but not their source) haven't changed.
This is fixed in the next changeset.
