Reduce dependency on gnulib by requiring C99 and POSIX 2008

- Remove gnulib modules c99, getopt-posix, strdup-posix, ssize_t
- Also remove obsolete gnulib module snippet/unused-parameter, use
  _GL_UNUSED instead of older _GL_UNUSED_PARAMETER, and instead of
  [[maybe_unused]].

Thanks to @dimztimz for providing the patch on which this commit is based.
