Make rev-list --objects work together with pathspecs
When traversing commits, the selection of commits would heed the list of pathspecs passed, but subsequent walking of the trees of those commits would not. This resulted in 'rev-list --objects HEAD -- <paths>' displaying objects at unwanted paths. Have process_tree() call tree_entry_interesting() to determine which paths are interesting and should be walked. Naturally, this change can provide a large speedup when paths are specified together with --objects, since many tree entries are now correctly ignored. Interestingly, though, this change also gives me a small (~1%) but repeatable speedup even when no paths are specified with --objects.
