we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach
Thanks to assistance from Lucas, Peter and Francisco
- added lowest/highest_threat tracking. This is currently defined as 2D distance. Room for improvement to make it 3D and be flight vector based instead of distance
- when trying to add a vehicle but the buffer is full, overwrite the lowest_threat/furthest
- added basic THREAT enum of high/low which means in or our of the 200m radius. Room for improvement here.
- contains a list of ADS-B vehicles
- does threat analysis and sets a flag when threat is found
- dynamically allocated database, consumes 40*25 =1kB of RAM when param ADSB_ENABLE = 1
