The 'ref_update.index' variable is used to store an index for a given
reference update. This index is used to order the updates in a
predetermined order, while the default ordering is alphabetical as per
the refname.
For large repositories with millions of references, it should be safer
to use 'uint64_t'. Let's do that. This also is applied for all other
code sections where we store 'index' and pass it around.
