The sampling rate, for both SCO and A2DP, had been harcoded
for convenience. But this is not a constant, because it
depends on the connected handset.
This commit retrieves the sampling rate for each new transport
and uses that information as a parameter for the stream creation
in the softmixer.

By monitoring the changes of names on dbus, and
by asking dbus for the list of available names at startup,
the bluealsa plugin can now be started at whatever time,
and is also robust to bluealsa restarts.
Moreover, since the bluealsa name has the HCI interface
has a suffix (org.bluez-alsa.hci0, for instance), there
is not need to hardcode the hci name.
Even better, the plugin supports several instances of bluealsa
(since the daemon needs one instace per hci device), and will
add a watch for added transports for every instance it detects.
Complete cleanup of the created streams in softmixer is done
when one watched instance disappears.
Finnaly, there is a new cmd line '-DWITHOUT_BLUEALSA' option to CMake,
for developpers that want to use 4A on host, without the bluealsa
library. Default build (SDK, bitbake) consider that the bluealsa
shared library is always available.
Notice that in the future, the bluealsa library might disappeared,
to be replaced by a full dbus interface to bluealsa.

The binder does not accept that synchronous calls are performed
in the context of a systemd event, it makes is abort.
To solve that, synchronous calls for creating/deleting bluetooth
streams in the softmixer are simply here replaced by asynchronous
calls.

Migrate from 'afb_api_call_sync_legacy' function to 'afb_api_call_sync'
function, therefore, handle function return and response json
differently from before.

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.
