bluetooth: Add state to transport objects

Browse source 
Transport objects have an associated state even though it's not
explicitly exposed in BlueZ's D-Bus API (prior to 5.0). Instead, the
state is implicitly represented in the profile-specific D-Bus interface
(i.e. org.bluez.Headset, org.bluez.AudioSink, etc.) but it can be
convenient that bluetooth-util would abstract this separation.
