The C standard only guarantees the sign of return value. The exact return
value is implementation defined.

- Replace `move_byte_forward()` with `memcpy`. In `memcpy` implementation,
it copies bytes forward from beginning to end. Otherwise, `memmove` unit
tests will break.
- Make `memmove` unit tests work.

Fix edge case where "0x" would be considered a complete hexadecimal
number for purposes of str_end. Now the hexadecimal prefix needs a valid
digit after it, else just the 0 will be counted as the number.

The Fuchsia build compiles the libc and test code with lots
of warnings enabled, including all the integer conversion warnings.
There was some sloppy type usage here that triggered some of those.

This allows others parts of the libc to use the mutex types without
actually pulling in public function implementations.
Along the way, few cleanups have been done, like using a uniform type to
refer the linux futex word.

These functions will be used in a future patch to implement
trigonometric functions. Unit tests have been added but to the
libc-long-running-tests suite. The unit tests long running because we
compare against MPFR computations performed at 1280 bits of precision.
Some cleanups or elimination of repeated patterns can be done as follow
up changes.

This suite is helpful is adding long running tests which take a long
