d6d465cdf4 output/Thread: fix assertion failure in CLOSE handler
Convert assertion to runtime check; this assertion could fail when the
output was closed due to an error before CLOSE arrived.

b6004b6837 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.

f86d6b0162 output/Control: move pipe initialization to the OutputThread
Un-protect the SharedPipeConsumer instance, and make it available in
the OutputThread only.  This gives more well-defined mutex protection.

ced3f320eb output/MultipleOutputs: reduce lock/unlock calls in EnableDisable()

a9d7293818 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.

If we have a pending command, then the player thread is already awake.
Even if not, we'll wake it up as soon as we have finished the command.
