Andrew Tridgell 11975223dd AP_Motors: added H_RSC_POWER_NEGC and H_RSC_SLEWRATE
this gives more control over throttle for petrol
helis. H_RSC_POWER_NEGC allows for a asymmetric V-curve, which allows
for less power being put into the head when landing or when sitting on
the ground. That can lead to significantly less vibration and chance
of ground oscillation. A heli not being flown with aerobatics does not
need to use high throttle at negative collective pitch.

The H_RSC_SLEWRATE allows for a maximum throttle slew rate to be
set. Some petrol motors can cut if the throttle is moved too
quickly. We had this happen at a height of 6m when switching from
ALT_HOLD to STABILIZE mode. It also lowers the chance of the blades
skewing in their holders with the sudden change of power when the heli
is disarmed. In general it is a bad idea to do instantaneous large
movements of a IC engine throttle.

Leonard Hall 4f0db2bc36 AP_Motors: learned THST_HOVER replace THR_MID
This holds the estimated thrust required for the vehicle to hover
expressed as a number from 0 to 1.  0 will be equivalent to outputting
SPIN_MIN (which is a number from 0~1 but in the full output range) and 1 is equivalent to SPIN_MAX (also 0~1 but in the full output range)

Leonard Hall 5a8fc6283e AP_Motors: replace throttle_rpy_mix with throttle_avg

prioritisation and simply provides overall maximum throttle (aka
throttle_avg) to the motors library

These parameters allow the motor PWM output range to be different from receiver's throttle input range
Also renamed throttle_pass_through to set_throttle_passthrough_for_esc_calibration and change the method's input to the 0 to 1 range instead of direct PWM value

Andrew Tridgell 60b3625950 AP_Motors: added hook for vehicle based thrust compensation
allow vehicle code to compensate for thrust effectiveness changes due
to properties outside the scope of AP_Motors. This allows for
compensation in tiltrotors and tiltwings.
