Rewrite code, but keeping the exact same semantic and behaviourHEADmain

- remove `#ifndef TWEETNACL_H` guard inside `tweetnacl.h`: as headers
  shouldn't include other headers;
- remove `#define sv static void` golfing alias;
- remove `#define FOR(i,n) for (i = 0;i < n;++i)` golfing alias;
- assert that the generated `tweetnacl.o` code is identical to the
  original code, available at `tests/assert-identical.sh`;
- remove all extra definitions from tweetnacl.h;
- rewrite code with the correct indentation, spacing and formatting;
- use C99 constructs over C89 (for loop variable declarations inside
  the parentheses);
- use smaller types on loop variables, mostly `u8` over `int`,
  `i64`, etc.;
- fix the public API;
- add fuzz targets;
