This patch introduce new modular API for bluetooth A2DP codecs. Its benefits are: * bluez5-util and module-bluez5-device does not contain any codec specific code, they are codec independent. * For adding new A2DP codec it is needed just to adjust one table in a2dp-codec-util.c file. All codec specific functions are in separate codec file. * Support for backchannel (microphone voice). Some A2DP codecs (like FastStream or aptX Low Latency) are bi-directional and can be used for both music playback and audio call. * Support for more configurations per codec. This allows to implement low quality mode of some codec together with high quality. Current SBC codec implementation was moved from bluez5-util and module-bluez5-device to its own file and converted to this new A2DP API.
