all: Update copyright header. This updates the copyright header to all be the same, which is pretty much an update of where to mail request for a copy of the GPL and the years of the MPD project. This also puts all committers under 'The Music Player Project' umbrella. These entries should go individually in the AUTHORS file, for consistancy.

output_plugin: added methods enable() and disable() With these methods, an output plugin can allocate some global resources only if it is actually enabled. The method enable() is called after daemonization, which allows for more sophisticated resource allocation during that method.

output: play from a music_pipe object Instead of passing individual buffers to audio_output_all_play(), pass music_chunk objects. Append all those chunks asynchronously to a music_pipe instance. All output threads may then read chunks from this pipe. This reduces MPD's internal latency by an order of magnitude.

audio_output_play(struct audio_output *ao);
audio_output: added method pause() pause() puts the audio output into pause mode: if supported, it may perform a special action, which keeps the device open, but does not play anything. Output plugins like "shout" might want to play silence during pause, so their clients won't be disconnected. Plugins which do not support pausing will simply be closed, and have to be reopened when unpaused. This pach includes an implementation for the shout plugin, which sends silence chunks.

output_thread: reimplement CANCEL synchronization The output thread could hang indefinitely after finishing CANCEL, because it could have missed the signal while the output was not unlocked in ao_command_finished(). This patch removes the wait() call after CANCEL, and adds the flag "allow_play" instead. While this flag is set, playback is skipped. With this flag, there will not be any excess wait() call after the pipe has been cleared. This patch fixes a bug that causes mpd to discontinue playback after seeking, due to the race condition described above.
