AP_InertialSensor: Added INS_MPU6K_FILTER option

AP_InertialSensor: allow specification of sample rate in init() call
...
this lets the caller not need to know the underlying sample rate. They
just ask for what rate updates happen.
This also changes the MPU6k filtering to be less than half the sample
rate

AP_InertialSensor: changes after review with Tridge.
...
sanity checking added to accelerometer calibration routine.
user feedback is sent using gcs_send_text_fmt instead of Serial.printf.

other small changes including renaming of functions and parameters.

AP_InertialSensor: changed read of sensor from MPU6000 to happen immediately
...
This reduces the delay between when data arrives and when it is used
by up to 1ms.
Added num_samples_available method to all InertialSensors to allow
main loop timing to be synced with sensors.

AP_InertialSensor_MPU6000: bug fix. DMP was being enabled by default so although the results were not being used, this caused a delay in the main loop
