[RFC v8 0/9] Add org.bluez.Telephony interface

Hello,

This set of patches replaces telephony drivers for HeadSet/HandsFree
Profiles by a new DBus interface (org.bluez.Telephony).

This will simplify BlueZ code by focusing on the Bluetooth
communication part and by letting the external application (i.e. oFono)
take charge of the Telephony tasks (AT parsing and modem specific code,
which can be removed from BlueZ code). So, it becomes simpler, easier
to maintain and debug.

External applications, which should implement AT parsing and telephony
part of HeadSet or HandsFree Profiles, will have to register a telephony
agent using this new interface.

Any comments appreciated.

Regards

PS: Since latest RFC :
  - update telephony.c to support multiple roles (headset.c and gateway.c)
Patch 1:
  - remove experimental flag for org.bluez.Telephony interface
  - fix Device property type of TelephonyAgent and send it upon connection
  - remove HS roles, will be integrated in patch 9
  - add watcher on agent disconnection in telephony.c
Patch 2:
  - remove deprecated APIs (IsConnected, IsPlaying and Play) of org.bluez.Headset interface
  - remove useless methods from org.bluez.HeadsetGateway
New patch 9:
  - move HFP HF server from audio/manager.c to audio/telephony.c
  - update audio/gateway.c to reflect this change and use new interface
