[PATCH] doc: Use a separate directory for new modules we add to PATH

["Arsen Arsenović" <arsen@aarsen.me>]

ChangeLog:

	* doc/baseconf.py: Inject dirname(__file__)/'modules' to path
	instead of just ``.''.
	* doc/gcc_sphinx.py: Moved to...
	* doc/modules/gcc_sphinx.py: ...here.

Evening,

This patch addresses a path mixup and provides a nice compromise between
convenience for the user and namespace cleanliness.  Further modules
that Sphinx imports internally from the GCC tree should also go into
this directory.  I moved gcc_sphinx since I knew of that one, but there
could be others I'm missing.

Tested on x86_64-pc-linux-gnu with ``make html''.

Have a great night!
