AP_InertialSensor: always sample at 200Hz in MPU6000
...
this changes the sampling to 200Hz regardless of requested rate, and
it is downsampled inside num_samples_available() using a shift. This
gives better noise resistance in ArduPlane.
This patch also makes it possible to update the filter frequency while
running, which is very useful for bench testing with a vibration
source

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.
moved ins parameters to new eeprom number to avoid conflicts with older parameters.
other small changes including renaming of functions and parameters.

...
Updated ArduCopter, ArduPlane and example sketches in AP_InertialSensor, AP_IMU and AP_AHRS libraries because they no longer need to pass in cs_pin to the constructor

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.
