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.
