[PATCH v3 00/10] update-index: migrate to parse-options API

This adapts "git update-index" to use the parse-options API (with resulting perks like nice "-h" output). Doing so reveals some potential improvements to parse-options infrastructure, too.

See [1] for the previous version. This version incorporates the last few suggestions by Stephen. The iffiest bit is still handling of the --cacheinfo option.

Thanks to Stephen and Junio for advice. Patches applies to maint, for no particular reason.
