[PATCH BlueZ v2 1/3] audio: Add ability to force CIS transport Links property

[PATCH BlueZ v2 1/3] audio: Add ability to force CIS transport Links property

[Frédéric Danis]

If bluetoothd is started in testing mode the Links property for CIS
is readwrite and can be used to force transport objects Links.
This can used to unlink transport objects by sending an empty array.

For unlinked transport objects, each transports needs to be acquired
separately.

This allows to pass PTS tests BAP/UCL/STR/BV-543-C and BV-546-C.
---
v1 -> v2:
  - Add testing mode check in bap_connect_io_cb()
  - Replace stream state check by checking that the stream is not linked
    before passing the connect event to all streams belonging to same 
    CIG/CIS.

From the discussion we had Ive assume we wouldn't be checking the
state here, since we don't check on bap_connect_io_cb either.

If the state is not checked this prevents to complete the transport 
acquire, ending with:
- for BV-543-C: profiles/audio/bap.c:setup_connect_io() setup 
0x50f000007a20 stream 0x50e000010dc0 io already up
- for BV-546-C: profiles/audio/bap.c:bap_state() stream 0x50e00000a5a0: 
enabling(3) -> disabling(5)
