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

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

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

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

The function returns the amount of time (in microseconds)
since the last call to Ch6().
ADC: added an enable_channel() API enable_channel() must be used before the Ch6() method is called to enable gathering of data on the required channels
