Added bluez sound playback support

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
