Jun Wu 36c4ce233d config: be compatible with Windows-style environment variables
Summary:
On Windows `%include` can have paths containing environment variables like
`%PROGRAMDATA%`. We already ship that kind of config files to users therefore
let's add support for that.

The change assumes `%` is not used as part of a normal path, which is probably
good enough for practical uses. If `%` does need to be legally used in a
filename, we can add escaping support later.

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).
