Stefan Filip 3f33e9f3e9 configparser: fix XDG config loading
Summary:
The spec for both XDG and Mercurial say that when the XDG_CONFIG_HOME variable
is not set, we should default to $HOME/.config.

Windows and macOS also have a designated config folder outside of the home directory.
The `dirs` crate provides consistent access to this folder. I see no harm in looking at config
 folders across all operating systems.

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).
