Quaternion: fix the gyro bias in centripetal and remove smoothing

The asin() in the pitch calculation can only take values between -1
and 1. This change ensures that the value is in range, and if it isn't
then we force a normalization. If that fails we reset the matrix

DCM: remove the taylor expansion optimisation for renormalisation
...
The sqrt() costs about 44usec on a 2560, which is small enough for us
not to worry about the speed.
This also changes the range of values where we declare a blowup to
much less likely, which means we can cope with larger delta_t glitches

Found free extra 256 bytes of RAM eliminate _clz use from libgcc
...
Believe it or not, changing / 2^31 to >>31 saved 256 bytes in the "d" segment.
The reason is that GCC version prior to 4.3.5 does not have a count_leading_zeros (clz) assembler macro, so it uses a 256 byte lookup table called _clz
The _clz table gets pulled in if you do 64 bit division.
This tiny change is the only place that we do long long division.
Changing to a shift saves 256 bytes of ram.

Add a CLI setup action to reset the magnetometer offsets
...
Since the magnetometer offsets are not available through the MAVLink parameter interface (since they are an AP_Var vector) this little feature allows them to be reset from the CLI. Useful if you somehow get bad offsets or if you change magnetometer. If you have a bad set of large offset values I have seen issues with the nulling algorithm have trouble converging to the proper values. I have never seen it have trouble converging from 0/0/0, so this could be a useful feature from time to time.
