Modified from floating point version. This includes changes to
vec3, vec4, mat33, mat44, and mag_cal.
Now fixed-point type (fp_*) functions is a function wrapper for both
fixed-point and floating point version operations:
* define CONFIG_FPU to use floating version mag_cal
* undef CONFIG_FPU to use fixed-point version mag_cal
Also, add tests for both float and fp types operations.
TEST=define CONFIG_FPU; flash on reef; See ARC++ magnetmeter app moving.
TEST=undef CONFIG_FPU; flash on reef; See ARC++ magnetmeter app moving.

Naming of many vector types and matrix types are not clear enough.
For example, we have:
vector_3_t, which is a vector of three int.
vec3_t, which is a vector of three float.
size4_t, which is a vector of four size_t.
mat33_t, which is a 3x3 matrix of float.
matrix_3x3_t, which is a 3x3 matrix of fixed point.
Besides, we have types like int8_t, uint16_t types.
To clearly distinguished types, the CL propose to,
For vector types, naming should be `$type + 'v' + $num + '_t'`:
vector_3_t becomes intv3_t
vec3_t becomes floatv3_t
vector 4 of uint16_t becomes uint16v4_t (which doesn't exist yet)
For matrix types, naming should be `mat$N$N_` + $type + '_t', where $N is the
matrix size:
matrix_3x3_t becomes mat33_fp_t # fp: fixed point
mat33_t becomes mat33_float_t

Code for hard iron calibration: Every seconds (or faster if enough
samples), find a sphere that fit the compass data.
Based on Android code.
BRANCH=smaug
