An server message id counter is included in every client to server message and an
expected id is included in every server to client message. This makes it safe to
re-send any message when the client is not 100% sure the server has received the
message, without having to worry about double handling on the server side.

Used with TrackMessageSizeInterceptor and with client-to-server Websocket message splitting (see #11648)

The original issue that the delimiter can not appear in the message (unescaped) is apparently fixed in Atmosphere 1.0.13

Also ensure the max size of a websocket fragment in bytes does not exceed the buffer size (#11842)

Change-Id: I768524bb54a5b8b9479dc7bda821256bd843dc52

* First part of a fragmented message prefixed by total message length plus '|'
* Atmosphere websocket buffer size set to 65536
* Fragment size is 65535 characters (Jetty requires less than buffer size)

Change-Id: I8bf872bbb03b86386070fdc99c14ea805dd2ef3a

* Can't open push connection during client-side init because CSRF token
is not available at that point. This allows simplifying the
initialization because the push state will not be checked until the
first response has been processed.
* Add helper for checking the CSRF token

For optimal performance, the script will still be included in the host
HTML if push is enabled when the UI is bootstrapped.

Change-Id: I2245b45434f3097c32fd3580267f692dce3b7649

* Asynchronous bidirectional communication
* Use Atmosphere as a backend
* Use websockets if available, fallback to HTTP streaming
* Push mode (disabled, manual, automatic)
  * Configurable via servlet parameter pushMode
  * Disabled: The default; regular AJAX communication
  * Manual: Need explicit UI.push() call
  * Automatic: push all UIs in session when lock released
* UI.push()
  * Push pending state and RPC to client asynchronously
  * Must hold session lock when invoking
