Teach pack-objects to use the filtering provided by the traverse_commit_list_filtered() interface to omit unwanted objects from the resulting packfile. Filtering requires the use of the "--stdout" option. Add t5317 test. In the future, we will introduce a "partial clone" mechanism wherein an object in a repo, obtained from a remote, may reference a missing object that can be dynamically fetched from that remote once needed. This "partial clone" mechanism will have a way, sometimes slow, of determining if a missing link is one of the links expected to be produced by this mechanism. This patch introduces handling of missing objects to help debugging and development of the "partial clone" mechanism, and once the mechanism is implemented, for a power user to perform operations that are missing-object aware without incurring the cost of checking if a missing link is expected.
