/**
* autoar_common_g_signal_emit:
* @instance: the instance the signal is being emitted on.
* @in_thread: %TRUE if you are not call this function inside the main thread.
* @signal_id: the signal id
* @detail: the detail
* @...: parameters to be passed to the signal.
*
* This is a wrapper for g_signal_emit(). If @in_thread is %FALSE, this
* function is the same as g_signal_emit(). If @in_thread is %TRUE, the
* signal will be emitted from the main thread. This function will send
* the signal emission job via g_main_context_invoke(), but it does not
* wait for the signal emission job to be completed. Hence, the signal
* may emitted after autoar_common_g_signal_emit() is returned.
