core: Prepare argparse.c to track additional info for options.
* src/argparse.c (opttable_t): New. (struct _gpgrt_argparse_internal_s): Use this instead of a ppointer to gpgrt_opt_t. (initialize): Copy options to the new tableand keep an original ordinal. (_gpgrt_argparse): Adjust for changes. (any_opt_conffile): Ditto. (find_long_option): Ditto. (arg_parse): Ditto. (long_opt_strlen): Adjust args. (cmp_ordtbl): New. (show_help): Print using the ordinal numbers.
We will need to keep extra information along with the options. This
changes prepares this by using a copy of the user provided option
table. The only new info is the original ordinal number which will
allow us to eventually do a binary search on the options but still be
able to print the help in the user defined way.
