        * glib.h:
        * gmain.c: there was a reference count race for hooks during invocation
        loops. since all (known) hook loop implementations, do currently start
        out with g_hook_first_valid() and iterate with g_hook_next_valid(),
        g_hook_first_valid() will now return a referenced hook, and
        g_hook_next_valid() will "eat" that, and eventually transfer it to
        the next hook. <sigh> unfortunately this requires g_hook_next_valid()
        to take the hook_list as additional argument.

        * gmain.c (g_main_iterate): adjusted callers of g_hook_next_valid().
