This function calls do_diff_cache() which eventually needs to set this
"istate" to unpack_options->src_index (*). This is an unfortunate fact
that unpack_trees() _will_ destroy src_index so we can't really pass a
const index_state there. Just remove 'const'.

(*) Right now diff_cache() in diff-lib.c assigns the_index to
    src_index. But the plan is to get rid of the_index, so it should
    be 'istate' from here that gets assigned to src_index.
