AP_Baro: improved barometer averaging
...
this changes the barometer calculations to floating point. On a MS5611
this is actually about twice as fast as the previous 64 bit
calculations, but gains us more accuracy as we are able to take
advantage of sub-bit precision when we average over 8 samples.

AHRS: make DCM drift correction not rely on accurate yaw
...
this uses a new formulation of the GPS based drift correction from
Bill Premerlani that rotates the error vector to avoid relying on
accurate yaw. This means we should get accurate roll/pitch correction
even with lots of magnetometer interference
It also makes it possible to fly a multicopter with no compass. It can
even navigate and correct yaw (slowly!)

Baro: average over all pressure/temperature samples on MS5611
...
this allows us to use the MS5611 barometer at its full 100Hz sample
rate (80Hz for pressure, 20Hz for temperature). The pressure and
temperature values are averaged between reads without adding any
latency. Previously the driver would throw away values between
readings
This also fixes a race condition in reading from the SPI bus that
could lead to bad values from the barometer

this fixes several problems with reading analog sources:
- we were getting poor values because we didn't wait long enough for

- we wasted a lot of CPU cycles waiting for conversions
- we were not taking averages over many samples, which we did with
the old AP_ADC driver on the APM1
