Andrew Tridgell 49cc0965c0 AP_InertialSensor: separate handling of FIFO and non-FIFO sensors
FIFO sensors produce data at a well known rate, but samples come in
bunches, so we can't use the system clock to calculate deltaT.

non-FIFO sensors produce data when we sample them, but that rate is
less regular due to timing jitter.

For FIFO sensors this changes makes us use a learned sample rate,
which allows for different clock speeds on sensor and system board.

For non-FIFO sensors we use the system clock to measure deltaT

the overall effect is a fix for sensors that produce samples at other
than the claimed datasheet rate.

Andrew Tridgell 624178f3be AP_InertialSensor: added INS_FAST_SAMPLE parameter
this allows enable/disable of fast sampling per IMU, making
experimentation easier.

It also fixes the fast sampling to always average over 8 samples, and
fixes the 9250 to use the correct accumulator when not doing fast
sampling

Lucas De Marchi f81dba2100 AP_InertialSensor: add doc to get_id() of backend
This is different from get_id() of Device and ultimately from each
sensor this this is identifying the backend, not the sensor.

Lucas De Marchi ace61087a1 AP_InertialSensor: remove product_id
We only leave the parameter there for backward-compatibility. However
product id on the inertial sensor is not much useful since it's only
kept for the first instance.

A better implementation per-gyro and per-accel is needed in order to
avoid problems with sensors taking the offsets configured for another
sensor.

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.

Lucas De Marchi 9c6bd38e91 AP_InertialSensor: sanitize includes
Due to the way the headers are organized changing a single change in an
inertial sensor driver would trigger a rebuild for most of the files in
the project. Time could be saved by using ccache (since most of the
things didn't change) but we can do better, i.e. re-organize the headers
so we don't have to re-build everything.

With this patch only AP_InertialSensor/AP_InertialSensor.h is exposed to
most users. There are some corner cases to integrate with some example
code, but most of the places now depend only on this header and this
header doesn't depend on the specific backends.

Now changing a single header, e.g. AP_InertialSensor_L3G4200D.h triggers
a rebuild only of these files:

Gustavo Jose de Sousa 25a499a41f AP_InertialSensor: use raw sample rate terminology
In order to avoid confusion between sample rate from sensor and sample rate
from the frontend class (AP_InertialSensor), use "raw sample rate" to refer to
the former.

The changes in the code were basically done with the following commands:

git grep -wl _accel_sample_rates | xargs sed -i "s,\<_accel_sample_rates\>,_accel_raw_sample_rates,g"
git grep -wl _set_accel_sample_rate | xargs sed -i "s,\<_set_accel_sample_rate\>,_set_accel_raw_sample_rate,g"
git grep -wl _accel_sample_rate | xargs sed -i "s,\<_accel_sample_rate\>,_accel_raw_sample_rate,g"

git grep -wl _gyro_sample_rates | xargs sed -i "s,\<_gyro_sample_rates\>,_gyro_raw_sample_rates,g"
git grep -wl _set_gyro_sample_rate | xargs sed -i "s,\<_set_gyro_sample_rate\>,_set_gyro_raw_sample_rate,g"
git grep -wl _gyro_sample_rate | xargs sed -i "s,\<_gyro_sample_rate\>,_gyro_raw_sample_rate,g"

And also with minor changes on indentation and comments.

Gustavo Jose de Sousa 6feea5f64f AP_InertialSensor: Backend: remove function _publish_delta_angle()
Delta angle calculation is now unified, so there is no need for such a method.
That also avoids developers thinking they need that method being called
somewhere in their new drivers.

Gustavo Jose de Sousa a3e2c82491 AP_InertialSensor: Backend: remove function _publish_delta_velocity()

somewhere in their new drivers.

Lucas De Marchi d3e8e8fd43 AP_InertialSensor: disable backend's copy constructor

Gustavo Jose de Sousa e06627dfcb AP_InertialSensor: Backend: add hook for new raw accel samples
