This allows you to arm the copter without any extra GCS commands while
in auto, and can be done from both the GCS, or the RC Tx. This is useful
for creating a simpler workflow.
This also allows you to set the auto_armed flag internally, which
bypasses the need to raise the throttle stick for the copter to start a
takeoff.
This exposed a problem where we would start running the controllers
before the EKF was at all initialized, if you switched into auto to
early. This now has a check that prevents us from running the mission
state machine until after the origin has been set. This was a suggestion
from @rmackay9.
When combined these options allow you to have the vehicle on the ground,
disarmed in auto with a takeoff waypoint loaded, then just arm the
aircraft and watch it takeoff. This is a feature we've had on quadplanes
for quite awhile now, and it has proven to be very nice for operators.
includes the following changes
winch_update called at 50hz
removed ability to set winch rate from ch6 tuning
remove wheel encoder
call winch library to log at 10hz
fix winch param prefix
RTL_ALT_TYPE replaces TERRAIN_FOLLOW param
return path built using rangefinder or terrain database
pre-arm checks for RTL_ALT_TYPE parameter
pre-arm checks of terrain data only run if RTL might use it
Fixes this compiler error:

This makes us look like Rover and Plane in terms of namespacing for the
Mode classes, and removes a wart where we #include mode.h in the middle
of the Mode class.
This was done mechanically for the most part.
I've had to remove the convenience reference for ap as part of this.
