Create traverse_commit_list_filtered() and add filtering interface to allow certain objects to be omitted from the traversal. Update traverse_commit_list() to be a wrapper for the above with a null filter to minimize the number of callers that needed to be changed. Object filtering will be used in a future commit by rev-list and pack-objects for partial clone and fetch to omit unwanted objects from the result. traverse_bitmap_commit_list() does not work with filtering. If a packfile bitmap is present, it will not be used. It should be possible to extend such support in the future (at least to simple filters that do not require object pathnames), but that is beyond the scope of this patch series.
