this fixes a problem where two different locations could both be
mapped to the same disk block in the terrain/*.DAT files. That meant
that pre-filled terrain on the microSD card would sometimes require a
download in flight. It also means that a RTL with loss of GCS could
sometimes fly through a region with no terrain data available
Other changes in this patch:
- allow for a 2cm discrepancy in the lat/lon of the grid
corners. This is needed to allow for slightly different floating
point rounding in tools that pre-generate terrain data to load on
the microSD
- added TERRAIN_OPTIONS parameter to allow the user to disable
attempts to download new terrain data. This is mostly useful for
testing to validate a terrain generator
this prevents a condition where the GCS can display the wrong value if
the 2nd PARAM_VALUE is lost
Note that groundstations can tell the set failed due to readonly in
the following ways:
1) look for the statustext: Param write denied (PARAMNAME)
2) see that the value came back with the old value, with index of
65535
3) can repeat the send, looking for (1) and (2)
Michael has proposed we add a PARAM_VALUE mavlink2 flags
extension. That would be nice, but we should still make this change to
fix the issue with mavlink 1.0
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

AC_WPNav: fixup max speed acceleration
AC_WPNav: simplify the initialisation of poscontrol's max speed
Changed at Leonard's request to keep things simpler
when GPS primary switches we were using a position which had not been
corrected for antenna offset. This was used for calculating the reset
for sensor change.
This fixes that (trivial fix) and also fixes a similar issue on
position reset
