fb907f5f76 output/Thread: KILL implicitly closes and disables the AudioOutput 
Reduce shutdown latency by two commands per output.

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.
