    Add private prototype for g_thread_init_glib()
    
    This function was never put in a header and was only used internally
    from libgthread, but we should keep the symbol around to avoid
    triggering any false-positives on ABI checkers.
    
    For -Wmissing-prototypes compatibility with this unusual case, we should
    add a private prototype in the .c file just before.
