debugobsolete: add formatter support (issue5134)

It appears that computing index isn't cheap if --rev is specified. That's
why "index" field is available only if --index is specified.

I've named marker.flags() as "flag" because "flags" implies a list or dict
in template world.

Thanks to Piotr Listkiewicz for the initial implementation of this patch.
