There is a race with the cleanup thread. While thin, it only has to
happen once. After this patch the race would have to happen... a lot.

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.
In the case that you:
- have previously done a successful SmartRTL flight
- get a mid-air gcs failsafe and enter SmartRTL
- recover from that gcs failsafe but remain in SmartRTL
- get another mid-air failsafe
then without this patch you will enter LAND mode.
When determining our failsafe action, we were looking at whether we
should just continue landing. To do that, we ask the current mode if we
are landing. Problem is that SmartRTL was handing back the wrong answer
- it was handing back ModeRTL's answer rather than its own, and
ModeRTL's answer was "yes, I'm landing", as that's the last state that
step 1 in the above list leaves that mode in.
This patch simply hands back the correct answer for, "am I landing"
also guided mode now retracts landing gear after takeoff
previously landing gear deployment was "level based" meaning the pilot could not override the gear's position
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

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.
