git-name-rev: add a --(no-)undefined option.

Rework get_rev_name to return NULL rather than "undefined" when a
reference is undefined. If --undefined is passed (default), git-name-rev
prints "undefined" for the name, else it die()s.

Make git-describe use --no-undefined when calling git-name-rev so
that --contains behavior matches the standard git-describe one.
