    gmacros: mark functions generated by autoptr macros as unused
    
    clang will warn with -Wunused-function if the g_autoptr macros are
    ever used inside a .c file.  This would break a lot of -Werror builds
    with clang.
    
    Mark such functions as explicitly unsed so clang will not warn about
    them.
