This patch adds initial support for BAP broadcast source.

The current implementation allows BAP source endpoint registration,
media transport creation, transport acquiring and sending broadcast ISO data.

Currently, one BIG containing one BIS is supported.

To test the current implementation use bluetoothctl with the following commands:
# endpoint.register 00001852-0000-1000-8000-00805f9b34fb 0x06
# transport.acquire /org/bluez/hci0/dev_00_00_00_00_00_00/pac_broadcast0/fd0
# transport.send /org/bluez/hci0/dev_00_00_00_00_00_00/pac_broadcast0/fd0 <file.wav>

The curent implementation checks that ISO_BROADCASTER is suported on the board so
"Check for ISO support in controller" patch is required

Silviu Florian Barbulescu (4):
  Split bt_bap_qos structure into unicast and broadcast structures
  Update bluetoothctl with support for broadcast source
  This adds the initial code for BAP broadcast source
  Update BAP plugin with broadcast source support

  To: linux-bluetooth; +Cc: Silviu Florian Barbulescu

This adds bluetoothctl support for broadcast source.

To test the current implementation use bluetoothctl with the following commands:
  endpoint.register 00001852-0000-1000-8000-00805f9b34fb 0x06
  transport.acquire /org/bluez/hci0/dev_00_00_00_00_00_00/pac_broadcast0/fd0
  transport.send /org/bluez/hci0/dev_00_00_00_00_00_00/pac_broadcast0/fd0 <file.wav>

I was trying to test this but it doesn't work for me:

transport.acquire /org/bluez/hci0/dev_00_00_00_00_00_00/pac_broadcast0/fd0
Transport /org/bluez/hci0/dev_00_00_00_00_00_00/pac_broadcast0/fd0 not found

Anyway I would suggest not to create the endpoint at
device_00_00_00_00_00_00 as that is sort of overkill just to be able
to broadcast, instead we can probably expose it at adapter level e.g:
/org/bluez/hci0/pac_bcast0, and we configure it like:

endpoint.config /org/bluez/hci0/pac_bcast0 /local/endpoint/ep3 [preset]

Btw, please use proper prefix e.g. shared/bap, client/player, etc, and
there are still some lines that are over 80 columns that need fixing.

Are you planning to continue working on this set? Or are you waiting
for some more feedback?
