6ddefdbcdf audio: Move StreamContext ownership out from StreamCommonImpl
Upcoming implementations of the streams of the primary module
will need to change the underlying stream type depending on
the current connected device. The stream context must persist,
thus its life time must be bound to the IStreamIn/Out implementation.
Move the StreamContext instance under ownership of StreamIn/Out.

Add StreamCommonImpl::onClose so that the owner of the context
may know when it is safe to reset it.

Re-arrange the order of the arguments when creating a stream
so that the context always comes first.

704aec434e audio: Add optional 'DriverInterface::getPosition' method.
This is a method which can be optionally implemented
by a stream in case it can provide more exact position,
for example by taking into account data in intermediate
buffers.

Implemented this method for StreamAlsa and StreamRemoteSubmix.

c337a8799b audio: Move tinyALSA-specific code to Module/StreamAlsa
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.
