args: Convert nng_opts_parse into a header only library using `nng_args_parse`.

The API is identical, except that some names have changed, and this is now a
header library in `nng/args.h` - so the core library does not need to carry this
code in binaries.  Being a header library also means it is not necessary to
link against NNG, and it does not include any parts of NNG; it only depends on
a standard C99 or C11 environment.
