Reviewers: shindig.remailer, awiner, plindner, Description: Continuation of 27117.
* New UriTests added for "." and ".." cases. Sussed out a bug. * StringTokenizer used rather than String.split(...) - yielded additional ~20% performance improvement. * LinkedList used over Stack. * ArrayList not used in place of LinkedList due to slight (almost 0 though) performance decrease measured.
