Add support for bluetooth telephonyguppy_6.99.3guppy/6.99.36.99.3
This adds support for bluetooth telephony.
A big rework in the softmixer internals has been
mandatory, in order to support dynamic streams creation
and deletions.
Bluetooth telephony relies on the recent evolutions
of bluez-alsa, the most important one being the
support of HFP over Ofono. The softmixer opens
PCM ioplugs provided by bluez-alsa.
Bluetooth SCO needs 2 streams, one for listening
and the other for talking. These streams are created
upon requests sent by the hal-manager.
The hal manager subscribes for bluez-alsa events
and request the list of availalble transports.
For each "attach" transaction verb, the softmixer
maintains a list of the all created objects
(sources, sinks, zones, ramps, streams, and more)
Additionnally, it creates a new verb when the attach
succeeds, that verb is typically something like
"sco_XX:XX:XX:XX:XX:XX", and the only supported action
at the present time is {"action":"remove"}, that performs
all the cleanup of the registered objects.
