Rewrite code, but keeping the exact same semantic and behaviourHEADmain

- assert that the generated `siphash.o` code is identical to the
  original code, available at `tests/assert-identical.sh`;
- remove unneeded `#define`s;
- rewrite code with the correct indentation, spacing and formatting;
- use C99 constructs over C89 (for loop variable declarations inside
  the parentheses);
- fix the public API.
