    g_log: mask log level before checking prefix flags
    
    We check if the log level is in the "prefixed" list by checking it
    against the g_log_msg_prefix bitfield.
    
    Unfortunately we were failing to mask by G_LOG_LEVEL_MASK first, so if
    the FATAL bit was set (for example) then it would never match.  This was
    the case for g_error().
