This allows for reusing the function in convert.c later.
Also, move it from attr.c to read-cache.c and add a use_index parameter
to specify a custom index_state since we are no longer enable to access
the static use_index variable from attr.c.

I am not totally sure whether read-cache.c is the best place for this...
