this switches ArduPlane over to use the L1 navigation controller, via
a generic nav_controller object pointer.
Note that the nav_controller controls all types of navigation now,
including level flight and heading hold. This provides a cleaner
abstraction than the old method of special case navigation handling

this changes STICK_MIXING from a boolean to a tri-state. With
STICK_MIXING=1 it now uses FBW style mixing. With STICK_MIXING=2 it
uses the old style of direct stick mixing.
- Allows use of hardware floating point on the Cortex-M4.
- Added "f" suffix to floating point literals.
- Call floating point versions of stdlib math functions.
this mode gives manual control when the roll or pitch is within the
set limits (the same limits as FBW mode), and prevents the pilot from
flying beyond those limits, essentially a "attitude limited manual"
mode
this allows direct passthru of throttle in STABILIZE and FBWA, which
is useful for nitro planes wher you have a throttle cut switch that
drops the throttle below normal minimum.
spoiler 1 and 2 are connected to 2 auxiliary channels, functions are
set to 16 on left wing and 17 om right wing respectively. Worked in
FBW + mode (auto etc.). No manual mode supported yet (need more
channels in my case).
this allows a user to setup the OBC failsafe system to forcibly crash
the plane (surfaces at limits, zero throttle) when the failsafe system
triggers. This is to allow APM to be used in the Outback Challenge. In
the OBC an external failsafe board also does this using the heartbeat
control pin, so this is an extra safety mechanism.
To prevent users accidentially triggering a crash, this code only
activates if FS_TERM_ACTION is set to to the magic value 42.
this allows you to select different altitude control algorithms. The
current choices are for the default (automatic based on if airspeed is
available), or to force a non-airspeed algorithm
The idea is to make it possible to use airspeed for some things (like
wind speed, speed scaling) but not for alt control
this removes the throttle suppression when any of the conditions are
met once, as otherwise flying slow below 10m could zero the throttle.
It also removes the use of airspeed for disabling throttle
supression. Otherwise a strong gust of wind can cause ArduPlane to
try to takeoff!
