Using sha1_object_info() is too heavy-weight; it starts from the sha1 and has to find the pack again (so not only does it waste time, it might not even find the same instance). In some cases, this problem is solved by helpers like get_size_from_delta(), which is used by pack-objects to take a shortcut for objects whose packed representation has already been found. But there's no similar function for getting the object type, for instance. Rather than introduce one, let's just make the whole packed_object_info() available. It is smart enough to spend effort only on the items the caller wants.
