[PATCH 10/10] object-file API: pass an enum to read_object_with_reference()

Change the read_object_with_reference() function to take an "enum object_type". It was not prepared to handle an arbitrary "const char *type", as it was itself calling type_from_string(). Let's change the only caller that passes in user data to use type_from_string(), and convert the rest to use e.g. "OBJ_TREE" instead of "tree_type". The "cat-file" caller is not on the codepath that handles"--allow-unknown", so the type_from_string() there is safe. Its use of type_from_string() doesn't functionally differ from that of the pre-image.
