C99 is now required.  Therefore HAVE_STDINT_H is no longer necessary.

encode_accessors.h: include "config.h" to allow header to stand alone

Minor cleanup of fuzz_target.cc

codespell: dependance  ==> dependence

Some compilers do header precompilation and this requires that each
header can stand alone.  Including config.h sets HAVE_STDINT_H.

- Include What You Use (IWYU) - add cstddef
- Convert to C++ includes of C headers
- Localize vars
- Combine definition and initialization of dest
- Convert C cast to C++ cast
- Remove unused source var

Use Cmake for fuzzing.
