hgweb: handle "parity" internally in webutil.diffs()
There's apparently no reason to have the "parity" of diff blocks that
webutil.diffs() generates coming from outside the function. So have it
internally managed. We thus now pass a "web" object to webutil.diffs() to get
access to both "repo" and "stripecount" attribute.
