Fix the draining of PCM capture stream in the PCM middle layer.
snd_pcm_drain() ignored capture streams, but it should change
the state to SNDRV_PCM_DRAINING.

Fixed rwlock around snd_iprintf() in sound core part.
Replaced with mutex.
Also, make mutex and flags static variables with addition of

Add four new information flags SNDRV_SEQ_PORT_TYPE_HARDWARE, _SOFTWARE,
