Removed __PHYSFS_platformRealPath().

It was an ugly piece of code, didn't work on The Hurd (apparently), likely
 dangerous in its incomplete understanding of Windows paths, and only
 used in places that should have given us normalized, absolute
 paths in the first place anyhow.

 - Deprecate PHYSFS_setSaneConfig(). It really should have been in the extras
   directory.
 - Clean up the sources to match my ever-changing coding style. :)
-- Remove realpath() for The Hurd, etc.
 - Get current CD list from windows without blocking? Is it possible?
