parse-options.[ch]: revert use of "enum" for parse_options()
Revert the parse_options() prototype change in my recent
352e761388b (parse-options.[ch]: consistently use "enum
parse_opt_result", 2021-10-08) was incorrect. The parse_options()
function returns the number of argc elements that haven't been
processed, not "enum parse_opt_result".
