Bluetooth: ISO: Add broadcast support
This adds broadcast support for BTPROTO_ISO by extending the
sockaddr_iso with a new struct sockaddr_iso_bc where the socket user
can set the broadcast address when receiving, the SID and the BIS
indexes it wants to synchronize.
When using BTPROTO_ISO for broadcast the roles are:
Broadcaster -> uses connect with address set to BDADDR_ANY:
> tools/isotest -s 00:00:00:00:00:00
Broadcast Receiver -> uses listen with address set to broadcaster:
> tools/isotest -d 00:AA:01:00:00:00
