Xavier Deguillard 5ede544f83 asyncpacks: remote unecessary Arc<Mutex> from the mutable packs
Summary:
Since all the methods of an aync mutable pack are taking the ownership of self,
there can only be one accessor to self, and therefore the Mutex is not
required. For the same reasons, the Arc can be removed.

This saves a bunch of atomic operation when operating on the mutable packs.

lib

Any native code (C/C++/Rust) that Mercurial (either core or extensions) depends on should go here. Python code, or native code that depends on Python code (e.g. #include <Python.h> or use cpython) is disallowed.

As we start to convert more of Mercurial into Rust, and write new paths entrirely in native code, we'll want to limit our dependency on Python, which is why this barrier exists.

See also hgext/extlib/README.md, mercurial/cext/README.mb.

How do I choose between lib and extlib (and cext)?

If your code is native and doesn't depend on Python (awesome!), it goes here.

Otherwise, put it in hgext/extlib (if it's only used by extensions) or mercurial/cext (if it's used by extensions or core).
