Andrew Tridgell b6ecce8329 AP_TECS: removed create() method for objects
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

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

Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers
Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

Andrew Tridgell d3d2ce3e0d AP_TECS: use full throttle in initial takeoff
during the first part of a takeoff when we have not yet reached the
target airspeed this forces the throttle to maximum. This fixes a case
where the throttle may drop too low during the first part of takeoff
and lead to a stall.

Tom Pittenger 595badce3e AP_TECS: rely on single flag for all land stage differences
recent fixes in Plane have made the stage more accurate so exceptions/hacks are no longer needed to differentiate between knowing if executing NAV_LAND vs being in stage_approach.

Andrew Tridgell 8ff932b61c AP_TECS: allow underspeed to end faster
we now can exit an underspeed condition if we stay above min speed for
3 seconds and also reach 15% above min speed. This prevents a problem
with the thrust line causing downpitch leading to a crash due to too
much throttle

Tom Pittenger 67e2db7975 AP_TECS: add TECS_LAND_PDAMP
// @Description: This is the damping gain for the pitch demand loop. Increase to add damping  to correct for oscillations in speed and height. If set to 0 then TECS_PTCH_DAMP will be used instead.

Tom Pittenger a139789693 AP_TECS: add TECS_LAND_TDAMP for land damp
+     // @Description: This is the damping gain for the throttle demand loop during and auto-landing. Same as TECS_THR_DAMP but only in effect during an auto-land. Increase to add damping to correct for oscillations in speed and height. When set to 0 landing throttle damp is controlled by TECS_THR_DAMP.

Tom Pittenger 67ce22660e AP_TECS: 1/3 new param TECS_LAND_SRC for Land Sink Rate Change
// @Description: When zero, the flare sink rate (TECS_LAND_SINK) is a fixed sink demand. With this enabled the flare sinkrate will increase/decrease the flare sink demand as you get further beyond the LAND waypoint. Has no effect before the waypoint. This value is added to TECS_LAND_SINK proportional to distance traveled after wp. With an increasing sink rate you can still land in a given distance if you're traveling too fast and cruise passed the land point. A positive value will force the plane to land sooner proportional to distance passed land point. A negative number will tell the plane to slowly climb allowing for a pitched-up stall landing. Recommend 0.2 as initial value.

Tom Pittenger e40bba3d13 AP_TECS: removing mission_cmd in TECS and making it bool is_landing

Tom Pittenger 5ba2bff85f AP_TECS: Reverse Thrust
Reverse thrust for controlled landings, even with much steeper approach slopes. This is achieved by allowing throttle demand to go negative to maintain a target airspeed. A Pre-Flare stage was added, triggered by an altitude, to allow for a slower airspeed just before land. That lower airspeed can be near stall.

Andrew Tridgell 36432e6515 AP_TECS: use climb rate filter consistently between DCM and EKF
we should use baro height not hgt_afe for the climb rate filter. This
makes the climb rate consistent with the one from the EKF. The lidar
correction comes in with the demanded height, not the observed height

Gustavo Jose de Sousa 1fbbe3ed81 AP_TECS: standardize inclusion of libaries headers
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

Andrew Tridgell 5a4ed85588 AP_TECS: added TECS_LAND_PMAX
this limits maximum pitch during the flare, which both reduces
integrator windup and prevents too high pitch which can cause a stall

Andrew Tridgell 060f553097 AP_TECS: provide a much smoother transition before flare
this moves the pitch constraint smoothly between unconstrained and
fully constrained over two time constants before the flare. This
greatly reduces the sudden pitch changes at flare
