merge-ort: add a special minimal index just for renormalization
renormalize_buffer() requires an index_state, which is something that
merge-ort does not operate with. However, all the renormalization code
needs is an index with a .gitattributes file...plus a little bit of
setup. Create such an index, along with the deallocation and
attr_direction handling.
A subsequent commit will add a function to finish the initialization
of this index.
