Initial rework to replace app framework usage

Changes:
- Remove "core" code related to WebSocket messaging for the app
  framework.
- Stub out hvac, navigation, network, and weather interfaces.  This
  allows building several of the demo applications without modification
  for now.  The network interface will definitely be reused to plumb
  in a new connman-glib library derived from the previous network
  binding.  The others may potentially be reused to plumb in other
  new backend implementations.
- Update the Network interface object constructor arguments to add a
  agent registration flag.  This prepares for the connman-glib
  switch and means users will not need to be updated twice.
- Update the Bluetooth interface to use a new bluez-glib library that
  is derived from the previous Bluetooth binding.  This has been
  successfully tested with a the Settings application.
- Remove signal-composer and voice API interface code as there are no
  direct replacements planned.  The signal-composer interface was
  effectively exposing the binding events, so has little reuse
  potential with a new backend.  For the voice interface, if some form
  of Alexa support becomes desirable, it can potentially be brought
  back for adaptation if required.
- Disable compilation of the remaining interfaces for now.  Some like
  map, pbap, and mediaplayer are very likely to be used as the basis
  for updating their associated applications, so keeping the code for
  the planned iterative development seems easier.
- Updated copyright lines in all touched files.
