Derrick Stolee c8dba310d7 path-walk: allow consumer to specify object types
We add the ability to filter the object types in the path-walk API so
the callback function is called fewer times.

This adds the ability to ask for the commits in a list, as well. We
re-use the empty string for this set of objects because these are passed
directly to the callback function instead of being part of the
'path_stack'.

Future changes will add the ability to visit annotated tags.
