d66f5a8590 output/alsa: replace PeriodBuffer::IsEmpty() with IsCleared() 
This assertion is not about whether all data has been consumed, but
about whether there has been any data at all.

c926021599 output/alsa: always redo DrainInternal() after writing 
Draining isn't finished just because the period_buffer has run empty.
It is only finished after snd_pcm_drain() has succeeded.

543776d9c9 output/alsa: check PCM state before calling snd_pcm_drain() 
Apparently, if snd_pcm_drain() returns EAGAIN, it does not actually
want to be called again; the next call will snd_pcm_drain() will also
return EAGAIN, forever, even though the PCM state has meanwhile
switched to SND_PCM_STATE_SETUP.  This causes a busy loop; to fix
this, we should always check snd_pcm_state() to see if draining is
really required.

8f6c750064 output/alsa: improve silence generator test in DrainInternal() 
There cannot be partial frames in the buffer, so we don't need
GetPeriodPosition(); it's enough to check whether head has been moved
in this period.

9fc1668de3 output/alsa: hold back snd_pcm_writei() until period_buffer is full 
This gives MPD more control, because attempts to avoid having partial
periods in the ALSA period buffer.  For example, this means that
DrainInternal() doesn't need to generate silence to fill the partial
period.

f44011519c meson.build: increase protocol version to 0.21.11 
Commit 1eae9339f2 added support for
multiple "groups" in the "list" command, and this change allows
clients to detect that this behavior, which had been documented for
several years, is now implemented properly.

2c3eeb7194 MusicChunk: pad MusicChunkInfo to a multiple of 8 bytes 
Workaround for a regression caused by commit
a06bf388d9, revealing a problem with
discarding odd numer of frames in the DSD_U32 and DoP converters,
causing distortions with DSD_U32 and DoP on 32 bit CPUs.
