- Delete all old map code

Plus lots of other cleanup

- MultiVehicleManager is a Qml friendly replacement for UASManager
- Vehicle is a replacement for both UAS and AutoPilotPlugin

- FirmwarePlugin is the new place for code which is specific to
firmware flight stack
- FirmwarePlugin currently supports flight mode apis
- Modify code to use new FirmwarePlugin support

Also:
- Prompts to reset trims to zero prior to calibrate
- Turned of radio check for now since it prevents spectrum bind

QGCUASParamManager and friends are replaced by FactSystem

New version using QtQuick along with an experimental Map Background

Also removed partially implemented an incorrect getCommunicationStatus
api

This signal passes the parameter type as well as param info

Plus a large number of other changes to allow for orderly shutdown of
objects without crashes or asserts. This is need for unit tests to
create/delete global state around every test.

This removes confusion as to whether you call UAS::requestParameters
(incorrect) or QGCUASParamManager::requestParameterList (correct) from
client code.

also adds AMSL output in ft
