lower risk of overrun.

Instituting Yaw Differential on Multirotors. Intent is to stop "rise on yaw input".

Since motors with increasing speed due to yaw input seem to generate more thrust that motors that slow lose thrust, thus net thrust goes up, causing copter to climb.
Values are a guesstimate, proven out by test flying. This could probably become a parameter.

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 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

AHRS: disable barometer for vertical acceleration
...
this seems to have been the cause of the 'flips' seen by Marco and
others. Testing by Craig and Alan shows that the flips are gone when
the barometric acceleration is removed.
It looks like a 5 point average filter is not enough to keep the
vertical acceleteration noise low. With high noise in the z axes, the
x and y axes are scaled back when the ge vector is normalised.

Compass: remove the need to call calculate() on the compass object
...
the new AHRS code doesn't use calculate() and the compass.heading
attribute. Instead it works on the raw magnetometer vector. This
change removes the internal calculate state from the compass object
and instead adds calculate_heading() for use by older code that
doesn't go via AHRS.
This significantly reduces the calculation involved in compass updates
The null offsets enable/disable code is also removed, as it is not
needed now that compass offsets are not linked to the AHRS state.

This makes 3 major changes:
1) fixes the scaling of the yaw drift correction term to fix the time

2) don't integrate the mag vector over multiple readings

to prevent omega_I picking up short term responses

GPS: fixed the UBLOX parser to handle unknown messages
...
the parser was broken in several ways:
1) when it received an unknown message it didn't update the ck_a and ck_b fields, so it
thought the message had a bad checksum, which meant it got out of protocol sync
2) the read() method would return false if the last message from the GPS was of an unknown type.
So we relied on the last msg always being one that we understand and want
3) the parser considered any valid UBLOX message to be 'new data', whereas we only actually get
a new fix when we get box a new position and velned message
4) the total message size per update is more than 128 bytes, but the serial port was opened
with only a 128 byte buffer, so we got corruption regularly
