Move fixedpoint.h to be accessible in /firmware.

Will need it soon enough.

Combine the contents of all the various fixedpoint.h files.
Not moving fixedpoint.c for now since I'm not sure where it
should be and it causes some dependency issues.

- /** CODECS - FIXED POINT MATH ROUTINES - USAGE
- *
- *  - x and y arguments are fixed point integers
- *  - fracbits is the number of fractional bits in the argument(s)
- *  - functions return long fixed point integers with the specified number
- *    of fractional bits unless otherwise specified
- *
- *  Calculate sin and cos of an angle:
- *      fp_sincos(phase, *cos)
- *          where phase is a 32 bit unsigned integer with 0 representing 0
- *          and 0xFFFFFFFF representing 2*pi, and *cos is the address to
- *          a long signed integer.  Value returned is a long signed integer
- *          from -0x80000000 to 0x7fffffff, representing -1 to 1 respectively.
- *          That is, value is a fixed point integer with 31 fractional bits.
- *
- *  Take square root of a fixed point number:
- *      fp_sqrt(x, fracbits)
