Andy Piper 6db09c9fdd AP_InertialSensor: keep a queue of gyro samples for use by the rate thread 
decimate the gyro window locally
configure rate loop buffer based on AP_INERTIALSENSOR_FAST_SAMPLE_WINDOW_ENABLED
allow backends to be updated from rate thread
output debug error if rate loop buffer overruns
add support for updating filter parameters independently of propagating samples
add rate loop config abstraction that allows code to be elided on non-copter builds
must be using harmonic notch to use rate thread
mediate fast rate loop buffer using mutex and binary semaphore
ensure gyro samples are used when the rate loop buffer isn't

Andrew Tridgell 0ebf9e7af5 AP_InertialSensor: pre-fetch instances for use in filter setup 
we use the instance numbers during filter configuration to check if
fast sampling is enabled. We need to ensure these instance numbers
have been setup before the filtering functions get called
