Hi,
this is the patch set I promised yesterday: it moves all audio outputs
into separate threads, where they can play the current chunk at the
same time, instead of sending each chunk separately to all outputs one
after another.
After a few tweaks, testing was positive.
There is still a lot left which can be done asynchronously,
e.g. initialization (asynchronous connect to shoutcast server, etc.).

Max Kellermann (15):
notify: declare "struct notify"
notify: make notify_init() failures fatal
notify: added notify_deinit()
notify: added macro NOTIFY_INITIALIZER
output: one thread per audio output
output: pass audio_format to plugin.init() and plugin.open()
output: set audio_output->open=1 in audio_output_task()
output: added audio_output_get_name()
output: added audio_output_closed()
output: make "struct audio_output" opaque for output plugins
output: document the audio_output elements
output: document the audio_output_plugin methods
output: call send_tag() only if device is on
output: semi-asynchronous playback
output: removed DEVICE_ON, DEVICE_OFF
