new param: LAND_ABORT_DEG
@Description: This parameter is used when using a rangefinder during landing for altitude correction from baro drift (RNGFND_LANDING=1) and the altitude correction indicates your altitude is higher than the intended slope path. Steeper slopes can result in crashes so this allows the option to remember the baro offset and self-abort the landing and come around for a another landing with the correct baro offset applied for a perfect slope. An auto-abort go-around will only happen once, next attempt will not auto-abort again. This operation happens entirely automatically in AUTO mode. This value is the delta degrees threshold to trigger the go-around. Example: if set to 5 deg and the mission planned slope is 15 deg then if the new slope is 21 then it will go-around. Set to 0 to disable. Requires LAND_SLOPE_RCALC > 0.
New param: LAND_SLOPE_RCALC
@Description: This parameter is used when using a rangefinder during landing for altitude correction from baro drift (RNGFND_LANDING=1) and the altitude correction indicates your altitude is lower than the intended slope path. This value is the threshold of the correction to re-calculate the landing approach slope. Set to zero to keep the original slope all the way down and any detected baro drift will be corrected by pitching/throttling up to snap back to resume the original slope path. Otherwise, when a rangefinder altitude correction exceeds this threshold it will trigger a slope re-calculate to give a shallower slope. This also smoothes out the approach when flying over objects such as trees. Recommend a value of 2m.
default value is 2 (so, enabled by default)
The path for the "non-board" environment cache file was hard-coded, which was
causing the error below when the build was configured with the --out option
value different from the default path.

That gives the change of storing that data in flash storage in some
architectures. That doesn't happen yet though, some extra changes are required
for that to happen.
We don't actually need all of them, since the second half is for the opposite
triangles. In that case we just need to negate the resulting vector when
changing basis.
That function was only being used by the unit tests and the benchmark. In order
to remove memory usage, the triangles will be removed, since we don't actually
need to keep them in real situations. Thus, this patch removes that function
and copy those triangles to the test and benchmark.
This is the second optimization. With that we don't have to iterate over the
umbrella's components.
The table below summarizes the mean CPU time in ns from the brenchmark results
on an Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz processor:
| Naive implementation | First Optimization | Second Optimization
------------------------------------------------------------------------
Min. | 26.0 | 28.00 | 26.0
1st Qu.| 78.0 | 48.75 | 39.0
Median | 132.0 | 57.00 | 41.0

3rd Qu.| 182.2 | 76.00 | 47.0
Max. | 234.0 | 98.00 | 54.0
If v is the null vector, then alpha * v is still the null vector for any alpha
as a real number. That means that the null vector doesn't cross any section.
This is a first optimization of the algorithm. The struct for the neighbor
umbrella has only one member, but new members will be added in the next
optimization.

This optimization reduces the mean time for the worst case (Max. line) by more
than 50%.
- Change the order of the icosahedron triangles so that there's a uniform way of
finding the opposite triangle. The order visually still makes sense.
- Change test to accommodate the order change.
