[PATCH BlueZ 0/2] Allow endpoint config without local endpoint argument

[PATCH BlueZ 0/2] Allow endpoint config without local endpoint argument

[Silviu Florian Barbulescu]

Update endpoint config command to create a local endpoint for broadcast
endpoint.
This will be used to configure a broadcast source/sink if
register endpoint is done from another application like PipeWire

Sample output from using the endpoint.config with endpoint and preset
to configure a broadcast sink to connect to a BIS.
The register endpoint for the broadcast sink has been done with PipeWire.

Sorry but will not gona fly, we don't have any business with endpoints
from other process in the system, in fact we might actually make it
strictly prohibit for third-party process to use SetConfiguration with
endpoint that do not belong their own D-Bus connection, same for
MediaTransport, they shall only be acquired by the process that
created them.

Also I remember quite clearly stating that we would move away from
using MediaEndpoint for Broadcast Sink, instead what we shall be doing
is enumerating BIS as MediaTransport directly so the likes of pipewire
can Acquire them directly without doing any configuration since they
are already configured over the air. Broadcast source will probably
require a special interface at pipewire side, or perhaps a dedicated
card which gets configured via some configuration file, etc, but we
shall not depend on bluetoothctl to configured it, that will just make
things more complicated than really helping.

We are investigating a solution with the broadcast source configuration
from PipeWire and also removing the MediaEndpoint reliance for the broadcast sink.
