In 'Module::setAudioPortConfig' allow subclasses to provide
their own suggested configuration.
In 'Module::populateConnectedDevicePort' provide the ID of
the device port instance that will be created as a result
of connecting an external device.
Also, expose 'ModuleDebug' flags to subclasses so that they
can know when device connections are simulated.

alsa_device_proxy keeps a pointer to alsa_device_proxy,
but does not own it. Thus, the lifetime of the proxy must
be no less than of the proxy. In the legacy USB HAL impl
they were stored together (struct alsa_device_info).
Implement an equivalent class (DeviceProxy) in ALSA utils.

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.
