[pulseaudio-discuss] [PATCH next v0 06/10] bluetooth: Use transport state to update port availability

From: Mikel Astiz <mikel.astiz at bmw-carit.de>
Use transport state to calculate the corresponding port availability,
and while doing so use bluetooth-util to receive profile state updates
instead of directly parsing D-Bus PropertyChanged signals.
