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.

86d3b25aec output/Source: add Fill(), ReadTag(), PeekData(), ConsumeData()

chunk contents.

f95e404be1 outputThread: optimize Command::OPEN
Try harder to skip steps (reopen filter, reopen output) if the
AudioOutput is already open.

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.

Add another condition to Reopen() which allows keeping it open.

add a new one for inter-thread communication.

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.

92eeb4969f output/Thread: don't wake up the player after receiving command in Play()
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.

df91f3738a output/Thread: remove a useless out_audio_format setting
Now that I can see the Reopen() method clearly, it is obvious that the
out_audio_format setting will get overwritten by the following Open()
call.

3392cbbd91 Emit a warning if the OutputThread fails to get realtime scheduling
This only applies to linux systems.  Here, sched_setscheduler() is
called to get realtime scheduling.  With this patch, the return value
of this function is now checked and a warning / error message is
generated if it fails.
