client: Add assistant submenu

This adds the initial implementation for the assistant menu in
bluetoothctl, to detect and print MediaAssistant objects.

The current BAP Broadcast Assistant implementation can be tested
by running bluetoothctl, connecting to a BASS Server, scanning
a Broadcast Source that is streaming a number of BISes with
audio capabilities matching the capabilities of the peer device,
and noticing the MediaAssistant objects being created:

bap: Notify scanned BISes to BASS

This updates the BAP implementation to also notify the BASS plugin about
scanned broadcast streams, or when a scanned broadcaster is removed. This
is needed for the BAP Broadcast Assistant role - the BASS plugin registers
MediaAssistant objects for each detected stream that matches the audio
capabilities of peer Scan Delegator devices.

bass: Register MediaAssistant objects

This adds an initial implementation of the BAP Broadcast Assistant role
in the BASS plugin, by introducing the MediaAssistant DBus object.

The BAP plugin implements the callback to probe Broadcast Sources and
parse the BASE. This commit adds 2 BASS APIs, that will be called by the
BAP plugin to notify BISes discovered in the BASE of a broadcaster to
BASS, or to inform the BASS plugin that a broadcaster has been removed.

For each BASS client session, the BASS plugin checks BIS caps against
the peer caps, and registers a MediaAssistant object for each match.

shared/bass: Add API to get GATT client reference

Some use cases require the BASS plugin to differentiate between client and
server BASS sessions - for example, the BAP Broadcast Assistant role only
considers client BASS sessions.

This adds a BASS API to obtain a reference to the bt_gatt_client structure
attached to the bt_bass session.

bap: Add API to get bt_bap matching device

This adds a public BAP API to obtain a reference to the bt_bap session
with a peer device.

shared/bap: Append bcast sink pacs to Sink PAC char

It is mandatory for a BAP Broadcast Sink to support the PACS Server role.
The Sink PAC characteristic should contain PAC records that expose
supported audio capabilities for receiving both unicast and broadcast
streams.

A BAP Broadcast Assistant acting as a GATT Client needs to discover the
Sink PAC characteristic on the BAP Scan Delegator peer (BAP Broadcast
Sink), in order to discover supported capabilities for receiving streams.

This commit updates the callback for handling read requests for the Sink
PAC characteristic, to also append Broadcast Sink pac structures to the
read response.

shared/bap: Allow checking bis caps against peer caps

A BAP Broadcast Assistant needs to match stream capabilities with
capabilities discovered in the Sink PAC characteristic on the peer.

This updates bt_bap_verify_bis to check the provided stream capabilities
against local or remote capabilities, depending on the bap structure
provided:

If the device is acting as a BAP Broadcast Sink and the bap session was
created after scanning a Broadcast Source, the stream caps will be matched
with the local broadcast sink PAC.

If the device is acting as a Broadcast Assistant and the bap session is a
client session with a BAP Scan Delegator, the stream caps will be matched
with the PAC records populated in the rdb at service discovery.

shared/bap: Remove unused param from bt_bap_verify_bis

This removes the codec parameter from bt_bap_verify_bis,
since it is not used.

shared/bap: Update bt_bap_verify_bis to receive caps

This updates bt_bap_verify_bis to receive the already merged L2 and L3
capabilities, instead of computing it internally.

22991. By Iulia Tanasescu <email address hidden> on 2024-07-18

shared/bap: Add separate API to merge caps

This moves the logic to merge L2 and L3 capabilities discovered
inside a BASE structure in a public API.
