Durham Goode 2919268555 revisionstore: auto-delete when we have too much pack data 
Summary:
In order to keep the hgcache size bounded we need to keep track of pack
file size even during normal operations and delete excess packs.

This has the negative side effect of deleting necessary data if the operation is
legitimately huge, but we'd rather have extra downloading time than fill up the
entire disk.

README.md

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).
