Subject: [PATCH] David Megginson: here are the generic protocols I implemented
 for ForeFlight's sim integration (also supported by Garmin Pilot).  The XATT
 one isn't fully working in Garmin Pilot (I've checked that the output is
 correct by sending it to a file), so I'd be grateful if anyone with an iOS
 device could try it in ForeFlight. The XGPS one is working flawlessly in
 Garmin Pilot on Android.
