[BlueZ,v5,5/8] transport: Broadcast sink: wait for user to select transport

Commit Message

Vlad Pruteanu July 31, 2024, 6:17 a.m. UTC

This changes the flow for transports created on broadcast sink side.
Transports are not automatically changed to pending anymore, instead
the user must first run transport.select on them which updates the
state to 'broadcasting'. This allows for the selection of the desired
stream when running the setup with PipeWire, which acquires any transport
that is broadcasting.
