mag_cal: Support fixed-point calculation.
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.
TEST=make runtests -j
TEST=make buildalltests -j
