* add optical flow arming check
* removed deprecated mavlink_log_critical
* change SYS_HAS_NUM_OF description, keep max sensor at 1 since multiple instances are currently not support.
* restructure if/else blocks
* remove temp field from airspeed.msg, adjust temp selection
* temp-sensor hirarchy: airspeed, ext. baro, default value
* directly use diff-press or baro temp in true-airspeed calc
* improve clarity
* add enum for temperature source in VehicleAirData.msg
* fix max-hagl restriction to position/altitude control
* max hagl vel restriction in ManAcc position mode
* use interpolate func, change naming
* simplyfied vertical vel limitation
* move velocity-constraint adjustment to StickAccelXY
* estimator gps check fail flag for spoofing
* warn whenever spoofing state changes to true, use default hysteresis to completely stop fusion
* dont introduce more GPS namings, GNSS instead
* flash: exclude mantis for cuav_x7pro
* reset position by fusion
* handle local_pos_valid for fixed wing in gnss denied
* [WIP] ekf2: setEkfGlobalOrigin respect current height reference and vertical position aiding
* global origin, also reset vertical pos without gps as ref
* fix wo gnss, that bitcraze ci passes
* revert some changes as requested
* remove duplicate reset messages
* undo unrelated whitespace changes, I'll fix it everywhere in a followup
* [SQUASH] ekf2: add vehicle_command_ack
* resetGlobalPosToExternalObservation consolidate logic
* remove gnss check from local_pos validation check
* reset when 0<accuracy<1, otherwise fuse
* replace gps param with flag
* ekf2: dead reckon time exceeded, respect ZUPT preflight if air data or optical flow expected
* subtract timeout from last inertial dead-reck, change fake pos conditions, save flash
