    cogl: remove OSX/WIN32 specific bits in favour of a stub winsys
    
    Until Cogl gains native win32/OSX support this remove the osx and win32
    winsys files and instead we'll just rely on the stub-winsys.c to handle
    these platforms. Since the only thing the platform specific files were
    providing anyway was a get_proc_address function; it was trivial to
    simply update the clutter backend code to handle this directly for now.
