output/alsa: multiply writei() result with out_frame_size
...
.. and not in_frame_size, because this relates to the frame size being
sent to ALSA. pcm_export_source_size() will then turn it back into
the in_frame_size scale.

output/alsa: fix out_frame_size formula, multiply with channels
...
The hard-coded "3 bytes" was wrong because it ignored the number of
channels.

audio_format: remove SAMPLE_FORMAT_DSD_OVER_USB
...
DSD-over-USB should not be a MPD core format, because it is not a
"natural" format; it is just a temnporary over-the-wire format. This
format has been implemented in pcm_export, and does not need to be
supported by pcm_convert.

audio_format: remove the packed S24 format
...
For simplicity, the MPD core should not have to deal with packing. It
is rarely used, and those plugins that need it should use the
pcm_export library instead.

Eliminate support for reverse endian samples from the MPD core. This

ALSA and CDIO currently).
