Xavier Deguillard f94c1f0c69 revisionstore: repack packfiles to get under 50 packfiles.
Summary:
When remotefilelog.fetchpacks is enabled, it's possible that 100 packfiles of
100MB each are present. In this case, every new packfiles that
hg_memcache_client would write will force an incremental repack, which will
only reduce the number of packfiles by a small number.

Let's have a simple heuristic that tries to bring the number of packfiles to be
lower than 50.

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).
