Compass: slightly relax HMC5843 calibration limits
...
Some users have reported Z axis values as high as 1.33. Their compasses
seem otherwise health so extending the limits slightly.

Add AVR compatibility header for missing math.h definitions.
...

on AVR (eg. #define sinf sin).

Compass: added COMPASS_LEARN and COMPASS_USE parameters
...
these allow you to control if the compass should be used for yaw and
if it should learn its offsets. This is useful for locking in compass
offsets once they are confirmed to be good, and for learning offsets
without using them in flights.
The default is to behave the same as previously, which is
COMPASS_LEARN=1 and COMPASS_USE=1

Compass: several fixes to compass calibration code
...
this changes the calibration code to require at least 5 good reads
from the compass during initialisation. The calibration is taken as
the average of the 5 values.
This also fixes the expected values for the 3 axes for the 5883 to
match reality.
We also save a bit of code space by adding a common rotate_for_5883L()
routine.

AP_Compass: fixed calibration of 5883L compass

this fixes a compass initialisation bug where if the first value from
the compass isn't in the right range we would set bad calibration
scaling factors.
This also changes the maximum acceptable calibration values to 2000,
which is needed for the 5883 compass
