Gustavo Jose de Sousa 5329e63742 AP_InertialSensor: allow publishing sample rate to frontend
That information will be used for a "centralized" vibration calculation.

Lucas De Marchi c66800dfec AP_InertialSensor: add singleton interface
In order to allow other libraries to use the InertialSensor we need a
way to let them to get the only instance of InertialSensor. The
conventional way to do a singleton would be to let the constructor
private and force it to be instantiated from the get_instance() method.

Here however we just call panic() on the constructor if there's already
an instance alive. This allows us to let the vehicles as is. Later we
can change it so they call the get_instance() method instead.

Lucas De Marchi caae933c28 AP_InertialSensor: Add support for auxiliary buses
Add an AuxiliaryBus class that can be derived for specific
implementations in inertial sensor backends. It's an abstract
implementation so other libraries can use the auxiliary bus exported. In
order for this to succeed the backend implementation must split the
initialization of the sensor from the actual sample collecting, like is
done in MPU6000.

When AP_InertialSensor::get_auxiliary_bus() is called it will execute
following steps:
	a) Force the backends to be detected if it's the first time it's
	   being called
	b) Find the backend identified by the id
	c) call get_auxiliary_bus() on the backend so other libraries can
	   that AuxiliaryBus to initialize a slave device

Slave devices can be used by calling AuxiliaryBus::request_next_slave()
and are owned by the caller until AuxiliaryBus::register_periodic_read()
is called. From that time on the AuxiliaryBus object takes its ownership.
This way it's possible to do the necessary cleanup later without
introducing refcounts, that we don't have support to.

Between these 2 functions the caller can configure the slave device by
doing its specific initializations by calling the passthrough_*
functions. After the initial configuration and register_periodic_read()
is called only read() can be called.

Lucas De Marchi 7d9579c5d8 AP_InertialSensor: identify backend with ID
Identify backend with an id, allowing other libraries to connect to
them. This is different from the _product_id member because it
identifies the sensor, not the board the sensor is in, which is
meaningless for our use case.

Lucas De Marchi 22c787058e AP_InertialSensor: allow to split detection and initialization
This allows backends to have a separate detection and initialization
logic. It doesn't change any backend yet and with the current code
there's no change in behavior either. This only allows
AP_InertialSensor::_detect_backend() to be called earlier so
AP_InertialSensor object can be used by other libraries. If it's not
called, later on AP_InertialSensor::init() will detect and start all
backends.

Tom Pittenger 2620a57700 AP_InertialSensor: Added is_still() check
very strict check that all axis are not vibrating much at all
new param: INS_STILL_THRESH used to be a vibration threshold for different platforms
// @Description: Threshold to tolerate vibration to determine if vehicle is motionless. This depends on the frame type and if there is a constant vibration due to motors before launch or after landing. Total motionless is about 0.05. Suggested values: Planes/rover use 0.1, multirotors use 1, tradHeli uses 5

Gustavo Jose de Sousa 7789aec85b AP_InertialSensor: 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.

Lucas De Marchi c3063f0ab2 AP_InertialSensor: MPU6000: be agnostic to I2C bus/address
This decision is better made by the caller rather than polluting the
driver with board-specific details.

Lucas De Marchi 4d4dac867e AP_InertialSensor: pass backend instead of pointer to function
Different detect() function might need different arguments and passing a
pointer to function here is cumbersome. For example, it forces to have a
method like "detect_i2c2" rather than allowing hal.i2c2 to be passed as
parameter.

Gustavo Jose de Sousa 42eb73a1d1 AP_InertialSensor: add LSM9DS0 backend
This adds the backend driver for LSM9DS0. This implementation is based on the
legacy driver coded by Víctor Mayoral Vilches (under folder LSM9DS0) and makes
some necessary adaptations and fixes in order to work properly. The legacy
driver folder was removed.

Gustavo Jose de Sousa c340e072f2 AP_InertialSensor: use accel instance max abs offset instead of a constant value
The calibration on LSM9DS0 was giving offsets between 4.0 and 4.2 on x-axis and
around 3.6 on y-axis. It turned out that those offsets were actually right.

The maximum absolute values of calibration offset should be a sensor
characteristic rather than a constant value for all sensors.

The constant value previously used (3.5 m/s/s for all axes) is set here as a
default maximum absolute calibration offset for every instance to keep it
working.
