This simplifies the invocation of cleanup, by only using
AlsaMixerTransactionDelete that performs the 3 actions
of cleanup, removal from list, and memory freeing.
Fixes a bug at MixerExit, because the first transaction was not
removed from the list and led to a double free error.
Also added a boolean parameter to AlsaMixerTransactionObjectDelete
(was AlsaMixerTransactionObjectForget before), that decides
wether or not the found object must be destroyed with its destructor
(for most of the cases) or simply freed in memory (which is needed
for loop device).

Leverage the new AVIRT driver for a more secure, more dynamically
configurable loopback sound driver.
To use, replace the file smixer-4a-default.json with
smixer-4a-avirt.json, at /usr/libexec/agl/smixer/etc.
The snd-avirt drivers are installed in AGL by default as of 6.99.2.
The existing snd-aloop configuration is not broken by this change.

- Replace controller binder functions definition with the binder ones.
and remove the last used submodules to use the separated libraries.
- Add liburcu as a project dependency in addition to the others ones.

Fixes most memory leaks in softmixer.
The concept of 'transaction' for dynamic streams has
been generalized to the objects created at startup.
The cleanup is done via a handle set through a atexit()
call.
Also added a missing strdup in alsa-api-loop, that fixes
a double free.
Warning, the bluez-alsa PCM are not closed in this
version. This is intentional due to a BUG in the
bluealsa ioplug PCM, that crashes upon close
(pthread_cancel is used to terminate the io_thread
and things get very bad. I have a pending fix for
that, relying on a cancellation pipe, but deeper
testing must be done).
As an effect, only one phone call can be made,
else 4a needs to be restarted

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.

This adds sound playback for incoming sound from
connected bluetooth devices.
In this version, the softmixer relies on a modified
bluez-alsa version (https://github.com/iotbzh/bluez-alsa),
that provides an ioplug PCM bluezalsa connection proxy.
The softmixer api has a new verb to dynamically set the
device to listen to:
afb-client-demo ws://localhost:1234/api?token=\uuid=123 smixer bluezalsa_dev '{"interface":"hci0", "device":"F6:32:15:2A:80:70", "profile":"a2dp"}'
In this way it is possible to switch from a bluezalsa audio source to
another without any further configuration.
For now, only interface hci0 is supported.
This commit also migrates the softmixer binding to API v3
