As we don't know the landing point altitude in non-mission landings, assume
the worst case (abort right before touchdown) and thus always climb
MIS_LND_ABRT_ALT on triggering an abort.

Add method for circular landing, that is used instead of the straight fixed-wing
landings in case the landing is not part of a mission landing.
Use straight landing if previous WP is valid, and the ciruclar otherwise.

_land_start_index is used to to start the mission from this item index, and to
avoid to publish a triplet.current.type=IDLE, we need to fill it with the actual
position setpoint that the vehicle should go to at the start of a mission landing.

* rtl: remove unconditional transition to land after descent
This was a bug, as it renders the above code lines useless.
This would cause a undesired FW landing for VTOL vehicles if
RTL_LAND_DELAY is above 0.
* rtl: head to center after loiter in VTOL FW
To get the same behavior for RTL with and without loiter before land for
VTOL drones.
* rtl: always go to descend state after return
Previously, the state would change directly to land if in MR and
RTL_LAND_DELAY was 0.0, but we will still wish to descent to
RTL_DESCEND_ALT at descent speed, instead of using landing speeds.
* rtl: mark head to center state as part of vtol transition
The next step in the sequence is transition to MC. By setting
vtol_back_transition we ensure that the acceptance radius is adapted to
the expected transition distance.
Do the same as DO_REPOSITION wit only the altitude field populated
and MAV_DO_REPOSITION_FLAGS set, which means:
- switch to Loiter mode if not already in it
- set the current altitude to what is specified in the altitdue field,
keep current altitude setpoint otherwise
- keep current position setpoint
- fall back to current estimated position in case a position setpoint
is not finite

Also applies to Loiters that are started due to the previous mode being over (Takeoff,
VTOL_Takeoff, Mission).

MIS_LTRMIN_ALt was used to limit the go-to altitude of a LOITER_TO_ALT (not the exit altitude,
but the altitude that the vehicle went to to fly to WP), and during landing abort to climb to
at least this altitude. The min entry altitude of LOITER_TO_ALT I remove with this commit, while
for the min alt during abort I added the new parameter MIS_LND_ABRT_ALT.

previously, the next position setpoint in the triplet was left unchanged during an abort, which meant that the abort loiter current point combined with land next point triggered the early landing config logic. this commit is only a hack to make things work temporarily.. this needs to be handled better.
Replace the existing check for the availability of a takeoff mission item with a combined
check for takeoff and landing item (or landing pattern). New param MIS_TKO_LAND_REQ
can be set to require only a takeoff, only a landing, both takeoff and landing, and
both or none. The latter is meant to be set if is e.g. deemed unsafe to start a flight
through a Takeoff WP without though defining a Landing - as then in case of a RTL the
vehicle doesn't follow a pre-defined path but instead only can do default RTL that especially
for FW and VTOL isn't always safe.

This was previously required to reset the flight speed after a VTOL transition,
but is now no longer required as the DO_CHANGE_SPEED commands are handles directly
in the controllers.

This fixes the issue where the init happended in the initializer list, at which point
the params were not yet initialized and thus resulted in random values for the init
values of _mission_item.loiter_radius and .acceptance_radius.

- this is a precaution to eliminate the possibility of getting stuck in
a loop trying to keep up with a high rate publication that could be
coming from a higher priority task
