Add script to rewrite revlog to workaround lack of parent deltas. Defaults to rewriting the manifest in the current repository. Based on a patch to rewrite-log by Benoit Boissinot that I found here: http://article.gmane.org/gmane.comp.version-control.mercurial.general/11908

inotify: use cmdutil.service instead of local daemonizing code
