[PATCH 28/56] bluetooth: Check if any transport is connected

[jprvita@xxxxxxxxx (jprvita@xxxxxxxxx)]

From: Jo?o Paulo Rechi Vita <jprvita@xxxxxxxxxxxxx>

Create a new function pa_bluetooth_device_any_transport_connected() to
check if there is any audio connection between the host and a remote
device.
