Make cookies use universal time instead of local time

Includes:
  * cowboy_clock:rfc2109/1 now expects UTC datetime
  * Rewrite of the cookie code to cowboy_http
  * Removal of cowboy_cookies
  * Add type cowboy_req:cookie_opts/0

Cookies should now be set using cowboy_req:set_resp_cookie/3.
Code calling cowboy_cookies directly will need to be updated.
