This prevents reentrancy if one hooked function calls into another.
For instance, the jemalloc implementation of `malloc` calls into `mmap`
while holding a lock, and our `mmap` hook calls `malloc`, so we must
prevent our `mmap` hook from running beneath our `malloc` hook.

The latest versions of greenlet now support 3.11, though 3.12 is not yet
supported. Update our tests to exercise our greenlet handling on 3.11.

Prior to greenlet 1.0, the "greenlet" module wasn't a Python package
containing a private extension module, it was just a public extension
module. Handle this case by updating our hacky detection for greenlet
being imported after tracking has begun to recognize "greenlet.*.so" in
addition to "_greenlet.*.so", and update our trace hook injection to
fall back to `greenlet.settrace` if `greenlet._greenlet` hasn't been
imported but `greenlet` has.

Note that we can't unconditionally call `greenlet.set_trace`, because at
the point where our hooks are being installed, it's possible that the
`greenlet._greenlet` extension module has been imported but the
`greenlet/__init__.py` module doesn't yet have a `settrace` attribute
because it hasn't yet done `from ._greenlet import settrace`.

These don't show up as lint errors since the scripts are given as string
literals, but when I copied these test programs out into standalone
scripts to try to investigate the greenlet 0.X issue, Black and flake8
caught these issues.

We switched from building our Linux wheels from a repo clone to building
them from a build sdist, but we missed making the same change for
building our macOS wheels.

Our TUI's `update_snapshot` method declares that it accepts any
iterable, but it expects to be able to iterate over the snapshot
repeatedly, which means that it does not accept generators or other
iterators that can only be iterated once.

Update its type annotation to require a sequence instead of an iterable,
and update the caller that was providing a generator to instead provide
a sequence.
