Andrew Tridgell 227609eef0 AP_Terrain: allow download of terrain data when no GPS lock
this fixes several issues:

 - allows users to download terrain data at home with no GPS lock

 - allows for a TERRAIN_CHECK without GPS lock

 - retries opening of files every 5 seconds to allow for remount of sd
   card after boot

Andrew Tridgell 7b7bf3ef86 AP_Terrain: fixed bug in disk offset calculation
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

Andrew Tridgell d175fb2f18 AP_Terrain: removed create() method for objects
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach

Thanks to assistance from Lucas, Peter and Francisco

Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers
Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

Tom Pittenger 73c5234633 AP_Terrain: cache status
instead of computing the terrain status on-demand, assign it in update() and cache the result. Then external tasks that check the status won't be doing terrain intensive calculations in their thread. All the calculations needed for the status were being performed in update already so this is an optimization.

Gustavo Jose de Sousa fcd1d4938a AP_Terrain: standardize inclusion of libaries headers
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

preloaded
