Extract code interacting with tinyALSA which is not
specific to USB into "abstract" module and stream
implementations ModuleAlsa and StreamAlsa. Also, move
utility code which does not need module or stream
context into Utils.
This facilitates implementation of the CF core HAL which
also uses tinyALSA, allowing to share common code.
