With a stream with low bitrate, user can't pause or resume the stream
near the end of the stream because current ALSA doesn't allow it.
If the stream has very low bitrate enough to store whole stream into
the buffer, user can't do anything except stop the stream and then
restart it from the first.
If pause and resume is allowed during draining, user experience can be
enhanced.
It seems that we need a new state to handle the pause + drain condition for
this case.
With this proposed change, the pause state in drain is invisible.
Indeed it's be much nicer to have a new state, e..g
SNDRV_PCM_STATE_DRAINING_PAUSED.
One concern is that states are defined in uapi/sound/asoc.h, so wouldn't
this have impacts on userspace as well? We'd change the value of
SNDRV_PCM_STATE_LAST.
