plugins: Convert all plugins to using mixer API for playback

Browse source 
pcm_play_data -> mixer_channel_play_data
pcm_set_frequeny -> mixer_set_frequency
pcm_play_stop -> audio_stop at startup / mixer_channel_stop at shutdown
pcm_is_playing -> mixer_channel_status

All of these have been removed from the plugin API.  Updated API docs to
clarify role of audio_stop() vs mixer_channel_stop()

Todo:  get rid of pcm_play_[un]lock().
