[RFC BlueZ 00/10] New Telephony interface for HSP, HFP and CCP

["Frédéric Danis" <frederic.danis@collabora.com>]

This will introduce a new Telephony interface wich is intended to be
shared by the profiles able to control telephony calls.

The idea is to split the call control interface from the audio streaming,
as it is done for AVRCP and A2DP.
As for A2DP, the audio part will be delegated to the audio daemon (like
PipeWire) by the creation of new endpoints for CVSD and mSBC, LC3 endpoint
already exists.

The interface is mostly based on the one done for PipeWire's native
backend.

This will simplify the qualification of the telephony related profiles as
the qualification will no more depend on external projects, and calls can
be controlled from bluetoothctl.

A first implementation allows to dial or hangup a call using HFP.
