ADSB mavlink packets

[geofrancis]

ardupilot can now send adsb packets down via the pixhawks telemetry connection to mission planner on the ground, as far as i know the pingRX is the only system to use it, if your SoftRF uav edition could send down adsb packet like the ping rx then you could get the FLARM data on mission planner.

SoftRF has support for MAVLINK 1.0's MAVLINK_MSG_ID_ADSB_VEHICLE message
for a long time ago, since this commit .

An example on how to use it with the Mission Planner had been given here: https://github.com/lyusupov/SoftRF/wiki/UAV-Edition
