Security fixes

  - A difference in cookie parsing between Tornado and web
    browsers (especially when combined with Google
    Analytics) could allow an attacker to set arbitrary
    cookies and bypass XSRF protection. The cookie parser
    has been rewritten to fix this attack.

Backwards-compatibility notes

  - Cookies containing certain special characters (in
    particular semicolon and square brackets) are now parsed
    differently.

  - If the cookie header contains a combination of valid and
    invalid cookies, the valid ones will be returned (older
    versions of Tornado would reject the entire header for a
    single invalid cookie).
