obsstore: break the repo → obstore → repo loop
This should help the garbage collector to do its job. On repository with many
markers, the memory pressure from the obsstore can get quite serious.

relnotes: mention chg behavior change when given --cwd

dispatch: change cwd when loading local config
Previously, the `_getlocal` function would not correctly load the repo config
when given a relative `rpath` and an alternate cwd via the `wd` parameter.
Normally when `--cwd` is specified, hg changes to the given directory before
attempting to load the local config (and therefore does not specify a `wd`).
The only time the function is called with `wd` set is when hg is running as a
command server (e.g., with chg), in which case each forked worker process will
attempt to configure itself via `_getlocal` before responding to the client.
When given a relative repo path, the worker fails to load the repo config,
detects a config mismatch with the client, and enters a redirect/respawn loop.
To fix this, we can simply change to the desired working directory during
config loading. (Note that simply concatenating `wd` and `rpath` won't work
in all cases. The repo path could be something more complicated than a simple
relative path, such as a `union:` repo.)

tests: work around libmagic bug in svn subrepo tests
libmagic 5.40 introduced a bug [1] wherein ASCII text files with fewer
than 3 distinct character values would be reported as binary data
rather than as text. This bug was later fixed in version 5.41 [2].
SVN uses libmagic to determine the MIME type of added files with missing
or unknown extensions [3]. This results in test failures on systems with
libmagic 5.40 installed:
$ echo a > a
$ svn add a
- A a
+ A (bin) a
A simple workaround is to change the test file's content to include
3 distinct ASCII values (including the terminating newline).

revlog: make _partialmatch fail fast on almost-hex inputs
Before this change, resolving a revision like [0123456789^] on
a large repo can take multiple seconds because:
- hg does not realize this is a revset, so it tries various things,
including _partialmatch(b"0123456789^")
- after the rust lookup fails, it falls back to pure hg
- pure hg takes all-but-last chars and converts them to binary,
which *succeeds*, so it does the expensive part.

setup: use the full executable manifest from `python.exe`
The manifest embedded by the build process (before the string here is added)
already accounts for the `<requestedExecutionLevel level="asInvoker" ...>`
setting. (Note that the PyOxidizer build is missing this, so it will likely
trigger the UAC escalation prompt on each run.) However, using `mt.exe` to
merge the fragment with what is already in the manifest seems to strip all
whitespace, making it unreadable.
Since Mercurial can be run via `python.exe`, it makes sense that we would have
the same manifest settings (like the supported OS list), though I'm unaware of
any functionality this enables. It also has the nice effect of making the
content readable from a resource editor. The manifest comes from python 3.9.12.
Note that this seems to strip the `<?xml ... ?>` declaration when viewed with
ResourceHacker 5.1.7, but this was also the state of things with the previous
commit, and `mt.exe "-inputresource:hg.exe;#1" -out:extracted` does contain the
declaration and the BOM in both cases. No idea why this differs from other
executables.

setup: unconditionally enable the `long-paths-support` option on Windows
I don't see anything talking about why this was experimental in the first place,
but maybe it was concern about the level of python2 support for it. But now,
both `python.exe` and the PyOxidizer build of `hg.exe` have a manifest that
enables it, so leaving it off would mean some Mercurial installations could
operate on a repo with long paths, and others couldn't. Note that only the wide
character functions (XxxW) will have the length restriction lifted.
Sadly, distutils applies `/MANIFEST:EMBED` to the linker in a way that can't
easily be turned off, so we can't use `/MANIFESTFILE` with `extra_preargs` on
`link_executable`. Fortunately, the compiler object provides a path to the
`mt.exe` it found during initialization, because the previous incarnation seems
to have assumed it is being run within an activated Visual Studio environment.
That causes MSYS builds to fail, and probably would have broke the CI
environment.

ci: bump pytype to 2022.03.29
This is as far as we can go without running into issues with the vendored `attr`
package. I tried updating that to the latest, and not only did it not fix the
issue, but test-util.py failed due to some poking at `attr` internals that
apparently is no longer valid.
The `libcst` package is now pinned to what I have locally because trying to
install the latest (0.4.7) complains that it can't find the Rust compiler. We
should probably use a requirements file instead (and/or figure out why it can't
find the Rust compiler), but I don't feel like dealing with another side quest.

These are newly detected by pytype 2022.03.21. Not sure what is going on here-
`realhostport` and `headers` are added outside of the constructor, so that makes

clicking through the class hierarchy, it shows in the py3.9 source code.
