Zeyi (Rice) Fan d552144478 configparser: move conversion related to a separated module 
Summary:
Move these conversion related function and trait out of `hg` module so EdenFS can use it too. Changes:

* Moved `get_opt`, `get_or` and `get_or_default` directly into `ConfigSet`.
* Moved `FromConfigValue` and `ByteCount` into `configparser::convert`.

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).
