Andrew Tridgell a0cf4e158a AP_Compass: revert change to RM3100 scale factor and increase scale limit
This reverts the change from #13895 and instead resolves the issue by
increasing the scale factor limit to 1.4

There is an open question as to why some RM3100 compasses show a
different scale factor (by about 1.25 times) to other versions of the
same sensor. As we haven't resolved this properly it seems the correct
thing to do is follow the datasheet but allow for a wider range of
scale factors to cope with the variation between sensors

Andrew Tridgell 6fd0ca36aa AP_Compass: added estimation of compass scale factor
this adds new COMPASS_SCALE, COMPASS_SCALE2 and COMPASS_SCALE3
parameters, which give the sensor scaling factor. It is used to
compensate for an incorrect scaling in a compass.

The 3D compass calibration process will set the correct value
automatically, otherwise users can set the value to a known value for
an existing compass

Andrew Tridgell 803f255c73 AP_Compass: fixed handling of duplication rotations
we have some rotations that are duplicated, such as ROLL_180_YAW_90
and PITCH_180_YAW_270. This copes with those in the auto-orientation
code

Andrew Tridgell 196ba0e858 AP_Compass: make COMPASS_ROT_AUTO take 3 values

Andrew Tridgell d15a4ad92a AP_Compass: improved error reporting, check all compasses
this uses extensions to the MAG_CAL_REPORT message to convey failures
of orientation checking.

It also checks all compasses, external or internal. It only tries to
fix the orientation if it is external

Andrew Tridgell 8b0f40b402 AP_Compass: implement automatic compass orientation

compass calibration, if COMPASS_ROT_AUTO is enabled.

Michael du Breuil deec4ec6af Compass: Rework compass calibrator
Summary of significant changes:
  -Autsave doesn't depend on STREAM_EXTRA3
  -Don't risk only saving one compass on copter if CAL_ALWAYS_REBOOT is set
  -Only calibrate compasses that are both health and marked for use (there was a inconsistency in handling the mask)
  -Fix incorrect failure reporting on DO_ACCEPT_MAG_CAL with a mask of 0 if a channel was specifically not started
  -Fix not starting the buzzer if the delay is set to 0 seconds
  -Always send MAG_CAL_REPORT until its acknowledged
  -Correct the field in MAG_CAL_REPORT for autosave to indicate if the compass had actually been saved, rather then being scheduled to be saved
  -Remmove unused public interfaces

Gustavo Jose de Sousa 46774136a6 AP_Compass: 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.

better check for convergence, comparison with initial fitness is a better way to determine if convergence occurs, if fitness has not improved compared to initial fitness it means optimiser has failed.
