parseopt: move definition of enum parse_opt_result up

Define enum parse_opt_result before using it in a typedef.  This avoids
the following compiler warning:

./parse-options.h:53:14: error: ISO C forbids forward references to 'enum' types [-Werror,-Wpedantic]
typedef enum parse_opt_result parse_opt_ll_cb(struct parse_opt_ctx_t *ctx,
^

While GCC and Clang both accept such a forward reference by default,
other compilers might be less forgiving.
