for input is changed to the following: reads from the device, instead of
being passed down to the slave PCM, will read the raw data from the
specified file. No file writes will take place in this case. In the
absence of this parameter, previous behavior is unchanged.

(1) Only interleaved reads (snd_pcm_file_readi) have been implemented
for now.

(2) File read()'s that return a number of bytes that's not a multiple of

rbuf_size_bytes, and rbuf_used_bytes members of the snd_pcm_file_t
struct will be used to address this problem in the future.

(3) Mind whether the PCM was opened in blocking mode. If so, we'll have
to loop until the buffer has been filled with read()'s.

Fix noisy output of dmix with two periods

Fixed the noisy output of dmix with two (or less) periods.
The dmix tends to give noise or XRUN when running with two periods
because of its implementation nature.  To avoid this, the start
position is aligned to the period size, so that the updates are synced
with interrupts of slave PCM.
