Andrew Tridgell 4a181ede62 AP_TECS: fixed descent or lack of climb bug 
this fixes a state where we either cannot climb or descend in an
uncontrolled manner in a TECS controlled mode

the conditions under which this happened were:

- _use_synthetic_airspeed_once was true due to quadplane takeoff
- we left _thr_clip_status as MAX from previous use of synthetic airspeed
- then run without airspeed

note that this can also impact users with an airspeed sensor if they
disable it or it fails in flight, particularly during a climb

Peter Barker 99012bd525 AP_TECS: ensure good TECS state before running update_pitch_throttle 
update_pitch_throttle can be called when update_50hz hasn't run in a very long time, or ever.  This requires a main loop rate >50Hz, and for the mode change to occur in the same loop that update_50Hz doesn't run but update_pitch_throttle does.

Andrew Tridgell 4f243aca02 AP_TECS: prevent rapid changing of pitch limits on landing approach 
when on landing approach we estimate time to flare based on two noisy
numbers, the vertical speed and height above ground. With noisy
rangefinders this can change rapidly, which resulted in the pitch
limit changing rapidly, leading to a porpoising movement

this limits the rate of change, and also prevents it coming down once
it has nosed up due to pending flare on approach
