Randy Mackay 06bef6e3b8 Parachute: clear release time when enabled
This resolves an issue in which the parachute could be suddenly released
when the user enabled the parachute.  The sequence that could have
caused this bad behaviour were (1) the parachute is triggered (2) the
user disables the parachute in the 0.5sec between the trigger and the
actual release, (3) the user re-enables the parachute and the old
release time from (1) is used.

Randy Mackay 19f1e7fec4 Copter: disable Parachute by default
This saves 1k of flash and we are desperately low on the APM1/APM2.
Hopefully we can find savings somewhere and re-enable it by default.

Randy Mackay ea64438ef9 Copter: RTL ensures heading is back to initial heading
This fixes the issue in which a short RTL_LOIT_TIME could cause the
vehicle's heading to be caught between it's heading when it arrived at
home and the initial armed heading.  With this fix it now waits above
home until the timer has run out AND the heading is within 2degrees of
the initial armed heading.

Randy Mackay e23115516d Copter: disarm after completing RTL
Note that an RTL command executed in AUTO mode will also disarm when it
lands and pilot's throttle is put to zero and no further commands will
be executed.  This is normally not an issue because missions generally
end with an RTL (instead of having the RTL in the middle) and a work
around is available in that the LAND command could be used instead of
RTL.

Randy Mackay ad99918fee AC_WPNav: recalc leash lengths if set_horizontal_velocity is called
Resolves bug in which do-set-speed allowed reducing the speed during the
mission but not increasing it.
Slow down distance is also recalculated.
Unnecessary call to calc_wp_leash_length removed from
set_spline_origin_and_destination.

Ju1ien 78a3e0f5a2 Copter: Hybrid removed Wind_comp_estimate filter
Removed useless call of function

hybrid.wind_comp_pitch);
Removed 10Hz filter for hybrid_update_wind_comp_estimate()

Andrew Tridgell 08412391f5 Plane: fixed a bug when switching to another mode from auto takeoff
when you exit auto and a takeoff is still in progress the flight stage
was not updated, which led to the throttle staying at maximum

Many thanks to Marco for finding this!

Randy Mackay 287af8f66e Copter: disable optical flow by default
We have run out of flash on the APM2, it was a choice between Hybrid
flight mode and OF_Loiter

Randy Mackay 55e7e1eb3e Copter: allow HYBRID to be disabled to save flash
Hybrid flight mode costs 4.5k of flash which currently puts us over the
limit for APM1 and APM2 unless optical flow or other features are
disabled

Ju1ien ff532a06ec Copter: Hybrid fixes to wind_comp, brake pitch timer, thr peaks
There was an error in the velocity axis used to update
brake_timeout_pitch (vel_right instead of vel_fw)

The wind_comp was not enough filtered for the Pixhawk (400Hz), so I
added a specific time constant (TC_WIND_COMP) to have the expected
filter with 400Hz controllers.

About throttle peaks, after some tests and from logs, they happen when
hybrid switches to loiter.
There is always a difference between Alt and DesiredAlt (DAlt), but,
when loiter engages, it initializes DAlt = Alt and the copter tries
immediatelly to reach that new setpoint. So the solution would be to
init_loiter_target() just as it was in pre-onion code : only x/y and not
z. and to be able to pass parameters like that
wp_nav.init_loiter_target(inertial_nav.get_position(), Vector3f(0,0,0));

Well, from this new code structure, it seems not possible with current
functions so I've used set_loiter_target that init position passed as
parameter and velocity to 0 (as expected).
BTW, I think there was something wrong with set_loiter_target function,
the "Vector3f& position" parameter was not used at all...
I moved the reset flag from init_loiter_target to set_loiter_target.

Ju1ien b3e8112d24 Copter: Hybrid fix wind_comp time constant
Corrected timer init values and wind_comp time constant to get the best
behaviour

Check if wider deadband required (current is 30).
We were using a comparison to a 70-100 cdeg deadband in our initial
code. The deadband was there to avoid unwanted switches in case of
inaccurate fingers/radio

Adjusted timers to 100/400Hz

I_term does not init when in hybrid loiter

(it prevents the text to speech announcing "65 thousand 6 hundred and
thirty five", which is quite annoying!)
