The unsigned long option parsing (including 'k'/'m'/'g' suffix parsing) is more widely applicable. Add support for OPT_MAGNITUDE to parse-options.h and change pack-objects.c use this support. The error behavior on parse errors follows that of OPT_INTEGER. The name of the option that failed to parse is reported with a brief message describing the expect format for the option argument and then the full usage message for the command invoked. This differs from the previous behavior for OPT_ULONG used in pack-objects for --max-pack-size and --window-memory which used to display the value supplied in the error message and did not display the full usage message.
