Most of the users of the read_tree_fn_t callback do not care about the "mode" per-se, they just care what type it resolves to. Amend this callback mechanism added in 3c5e8468a93 (ls-tree: major rewrite to do pathspec, 2005-11-26) to pass the object_type, and use it whenever possible. In the archive.c code we could go much deeper with this refactoring, after getting the "mode" that code will pass it around itself and into archive-{tar,zip}.c. As far as I can tell we could drop the mode early, and just pass "enum_object_type type, int is_executable". That would be slightly redundant space-wise, but would assure us that we're not writing out raw modes found in trees, but are normalizing them. But that particular refactoring would be larger than what I'm trying to accomplish here, so let's leave it for now.
