output/Source: release the mutex while the filter runs
...
The filter can take some time to finish, even more so on a weak
machine with a saturated CPU. By not holding the mutex during that
time, we can reduce PlayerThread latency a lot, because that thread
needs to synchronize a lot with all outputs.

output/Thread: wake up the player thread periodically while playing
...
Without this, the pipe would run empty very often, which may result in
an xrun if the roundtrip to the PlayerThread and back takes too long.
By waking up the PlayerThread before the pipe runs empty, we make MPD
much more latency tolerant, which is a major optimization.
