In this patch series was dropped all patches which are already applied
in git master branch.

There are 2 new patches: "Fix A2DP codec API to provide information about
data buffer" and "policy: Set initial A2DP profile which bluez already
activated".

So with profile/codec switching we can relay on bluez functionality of
remembering the last used codec.

Changes in v9:
 * Fix parsing uuids of remote SEP endpoints
 * Remove wrong assert in FastStream codec
 * Fix logic in SBC codec for checking if two config/capabilities are
   compatible
 * Split SBC UHQ into two sub-codecs - it is needed to ensure that
   remote endpoint does not choose bitpool for dualchannel configuration
   (38) and channel mode for stereo configuration -- which is SBC middle
   quality configuration
 * Simplify encode and decode functions for aptX codec
 * Change FastStream codec code which handles bugs in firmware
 * Fix A2DP codec API to provide information about data buffer
 * Ensure that module-bluez5-discover does not unload
   module-bluez5-device when codec switching operation is in progress
 * Set initial A2DP profile which bluez already activated
