This updates the input prompts for broadcast endpoint register and
config.
To register a broadcast endpoint, the user will be asked to enter
the supported stream locations and context types.
At broadcast source endpoint config, the user will provide stream
config options: The BIG that the new stream will be part of, the
stream Channel Allocation, and the metadata of the subgroup to
include the stream. These options will be used to configure the
BASE and the BIG.
The flow to create a Broadcast Source is the following:
[bluetooth]# endpoint.register 00001852-0000-1000-8000-
00805f9b34fb 0x06
[/local/endpoint/ep0] Auto Accept (yes/no): y

[/local/endpoint/ep0] Locations: 3
[/local/endpoint/ep0] Supported Context (value): 15

Endpoint /local/endpoint/ep0 registered
[bluetooth]# endpoint.config /org/bluez/hci0/pac_bcast0

[/local/endpoint/ep0] BIG (auto/value): 1
[/local/endpoint/ep0] Enter channel location (value/no): 3
[/local/endpoint/ep0] Enter Metadata (value/no): 0x03 0x02
0x04 0x00
To create a Broadcast Sink, enter the following:
[bluetooth]# endpoint.register 00001851-0000-1000-8000-
00805f9b34fb 0x06
[/local/endpoint/ep0] Auto Accept (yes/no): y
[/local/endpoint/ep0] Max Transports (auto/value): a
[/local/endpoint/ep0] Locations: 3
[/local/endpoint/ep0] Supported Context (value): 15
[bluetooth]# scan on
[NEW] Endpoint /org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/
pac_bcast0
[bluetooth]# endpoint.config
/org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/pac_bcast0
/local/endpoint/ep0 16_2_1
This adds .name field to struct capabilities which is then used to form
the endpoint object path so it is easier to identify the endpoint
capabilities:
[bluetooth]# endpoint.list local
/local/endpoint/pac_snk/lc3
/local/endpoint/pac_src/lc3
/local/endpoint/bcaa/lc3
endpoint.config where taking different arguments for broadcast which is
not recommended with shell as it doesn't support such a thing.
So instead of taking different arguments for broadcast both remote and
local endpoints shall be passed but in case of broadcast source both the
remote and the local endpoint actually refer to the same endpoint
registered by bluetoothctl:
endpoint.config /org/bluez/hci0/pac_bcast0 /local/endpoint/ep2 16_2_1
If there are multiple locations, aka. multiplexing, being selected then
that should be accounted properly on the SDU size since the presets only
account for just 1 channel.

This makes use of ChannelAllocation when present on SelectProperties
dictionary which is then passed on to bluetoothd and send over as part
of Codec Configuration:

Added support for broadcast sink registration using the 0x1851 UUID.
Added support for remote endpoint creation when a broadcast source
is discovered.
Added support for creating a local endpoint when the broadcast sink
endpoint was registered from an external application (Pipewire).
To test this feature use the following commands:
[bluetooth]# endpoint.register 00001851-0000-1000-8000-00805f9b34fb 0x06
[bluetooth]# scan on
[NEW] Endpoint /org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/pac_bcast0
[bluetooth]# endpoint.config
/org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/pac_bcast0
/local/endpoint/ep0 16_2_1
Linked (bi-directional) transports can be acquired on single D-Bus
method call which was not being handled properly by the current code
causing unexpected errors.
This adds bluetoothctl support for broadcast source.
To test the current implementation use bluetoothctl with the commands:
endpoint.register 00001852-0000-1000-8000-00805f9b34fb 0x06
endpoint.config <created endpoint> <local endpoint> 16_2_1
transport.acquire <created transport>
transport.send <created transport> <file.wav>

This adds support for Metadata in BAP profile.
In order to register zero Metadata, 0 shall be
entered when prompted.

This adds support for Company ID and Vendor Codec ID in BAP profile.
This also adds handling of Vendor Specific Coding format for BAP
Profile.
Now it allows to enter zero codec capabilities for vendor codec.
In order to register zero codec capabilities, 0 shall be
entered when prompted.
Commands transport.send/receive were not settings any completion
callback so this makes sure it uses transport_generator to generate the
list of transport that could be used to send.
This adds support for a custom preset which asks the user to enter its
configuration:
[bluetooth]# endpoint.presets 00002bc9-0000-1000-8000-00805f9b34fb custom
[Codec] Enter frequency (Khz): 48
[Codec] Enter frame duration (ms): 10

This fixes the following warning:
