ADC: change adc.Ch() to return a float
...
this gives us a bit more precision in airspeed measurement, and costs
us virtually nothing as we are converting to float immediately after
getting the value

AP_ADC: rework ADC library to use PeriodicProcess and ISR_Register

this makes it possible to build the ADC library when another driver
may also want that interrupt

Heavy Accel Filter + mild Gyro Filter. To use, filter_result must be set to true on ADC. Off by default.

ADC: randomise the sampling rate

this is based on suggestions from Kari and Mike, and should reduce the
aliasing effects we get from the simple averaging

change ADC sample rate to 1kHz
...
this costs us about 9% of our CPU, but should make aliasing much less
of a problem.

ADC: re-work for ADC code for full resolution and accurate timing
...
this changes the ADC code to return the full resolution of the
sensors. It also adds a new Ch6() interface that returns 6 channels at
once, so the IMU can read 3 accelerometers and 3 gyros at once, and
get the exact time that the values were accumulated over
