Adds support for bluetooth audio through bluez-alsaguppy_6.99.4guppy_6.99.3guppy/6.99.4guppy/6.99.36.99.46.99.3
Implements a new bluealsa plugin to the HAL manager, reacting to the changes of the available transports. This plugin is linked with the new bluealsa.so shared library. New transports (SCO & A2DP) result in softmixer invocations of the "attach" verb, that creates the new capture (eg, A2DP capture from bluealsa ioplug PCM, SCO microphone capture), playbacks (SCO playback to a softmixer zone, and SCO output to bluealsa iogplug PCM). When a transport disappears, the hal manager calls the transaction deletion verb that will tell the softmixer to remove the created streams and associated objects.
