0aa2fe7a0b AP_Compass_AK8963: fix sem handling
In case of error or zeroed data, the i2c semaphore wasn't given.
It happened at first startup on Bebop and caused a failure:
"PANIC: failed to take _bus->sem 100 times in a row..."

8240e5ae65 AP_Compass: AK8963: reduce bytes read
We are not using INFO and ST1 registers, so there's no need to read
extra 2 bytes for each transaction.

2b9c46e1ff AP_Compass: AK8963: don't oversample AK8963

chance of errors.

6c2ceea165 AP_Compass: AK8963: remove author and connection comment
Authorship and how sensor is connected get outdated (as it already is).
Our code is on git so let it track who wrote each line.

8ab33c46ce AP_Compass: revisited AK8963 code
Reduced duplication a bit and revisited the update method which is now
split into several logical hunks.

fffedae3e0 AP_Compass: AK8963: reduce stack usage and zero out buffers
Since we are not using MPU9250's fifo to get samples from AK8963 we will
always read only 1 sample (+ control registers).

37734886a5 AP_Compass: AK8963: remove repeated comments
No need to repeat the same comments on 3 different places. Instead add a
single comment to explain how start_measurements() and read_raw() are
related.

27d95b67a8 AP_Compass: AK8963: remove state machine
Don't use a state machine in AK8963: the start_measurements() method
should be called only once.  Even if there's a magnetic sensor overflow
the only thing we should do is to discard the new data.

This also moves the _collect_samples() method to be inside _update()
since it's the only place it should be called from, the one running on
the timer thread.

e232543fca AP_Compass: AK8963: change initialization and rename methods
We need to check the AK8963's id before anything else Here we are
reordering the calls to _calibrate() and _check_id(). After that we
don't need to read and write again the AK8963_CNTL1 register.

While at it do some renames as well:
	- _configure() -> _setup_mode(): since now there's a
 	  _bus->configure() it became confusing what actually it's
	  doing.
	- make error messages say what we were actually trying to do but
	  couldn't. Also remove PSTR since this is linux-only.
	- start_conversion() -> start_measurements():  We are instructing the
          bus to start to get the samples, not to tell the chip to start an
          analog->digital conversion like in other sensors.

ae5d9baddb AP_Compass: AK8963: remove defines not used anymore
The MPUREG_PWR_MGMT_1 defines were used when we cared about the MPU9250
initialization code. Now all initialization is done by the MPU9250 class
itself, so remove these defines.

Also remove AK8983_SELFTEST_MAGNETIC_FIELD_ON that is never used and let
the defines always with 2 bytes to improve readability.

cae895bfdf AP_Compass: AK8963: group members together
Besides being semantically related, this removes the hole due to

Uses reimplemented AK8963 driver. There's also no need trying to detect this

Otherwise, get_field() will return NaNs after once every few calls to
read() during compassmot on PX4 platforms, which causes compassmot to fail.

This is a quick hack around the deeper issue, which could be something
like the PX4 mag driver experiencing starvation and skipping mag reports,
buffer overrun or something else that causes mag reports to be dropped.
Or perhaps we should never expect in the first place that we will always
receive at least one mag report between calls to read().

189d635493 AP_Compass: constrain compass offsets to +/- 2000
this is prompted by a user log showing NaN compass offsets, resulting
in a crash. The patch ensures we never end up with NaN offsets, and
also constrains the offsets to a reasonable limit

54562b0b9a AP_Compass: prevent bad initial values from affecting HMC5883 calibration
the first couple of values after we enter strap mode may be low, but
just above our 0.7 threshold. We now discard the first two values to
prevent these affecting the average.

Also added some commented out debug code and a comment on the scaling
of the calibration code

84fdff4cd6 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.
