This patch adds support for multiple BISes in broadcast sources.

Example commands:
Create a local endpoint and an endpoint for BIS1:
endpoint.register 00001852-0000-1000-8000-00805f9b34fb 0x06
[/local/endpoint/ep0] Auto Accept (yes/no): y
[/local/endpoint/ep0] Max Transports (auto/value): a
[/local/endpoint/ep0] Locations: 0x03
[/local/endpoint/ep0] Supported Context (value): 0

Configure BIS1, create BIS1 transport and endpoint for BIS2:
endpoint.config /org/bluez/hci0/pac_bcast0 /local/endpoint/ep0 48_4_1
[/local/endpoint/ep0] BIG (auto/value): 0x01
[/local/endpoint/ep0] Enter channel location (value/no): 0x01
[/local/endpoint/ep0] Enter Metadata (value/no): n

Configure BIS2, create BIS2 transport and endpoint for BIS3:
endpoint.config /org/bluez/hci0/pac_bcast1 /local/endpoint/ep0 48_4_1
[/local/endpoint/ep0] BIG (auto/value): 0x01
[/local/endpoint/ep0] Enter channel location (value/no): 0x02
[/local/endpoint/ep0] Enter Metadata (value/no): n

For multiple BISes acquire must be called on all transports
before the BIG is created:
transport.acquire /org/bluez/hci0/pac_bcast0/fd0 
transport.acquire /org/bluez/hci0/pac_bcast1/fd1
.....
transport.release /org/bluez/hci0/pac_bcast0/fd0
transport.release /org/bluez/hci0/pac_bcast1/fd1

Silviu Florian Barbulescu (7):
  bap: Remove set lpac user data at bcast ep register
  shared/bap: Add support to create multiple streams for the same pac
  bap: Create a new endpoint available for the next BIS configuration
  bap: Split bap_state and bap_connecting in two functions
  shared/bap: Check the state of all the streams with the same BIG ID
  bap: Set the generated BASE on all setups from the same BIG
  shared/bap: Generate single BIS BASE for a config with BIG ID 0xFF
