WebSocketHandler implementations:
- methods must deal with exceptions locally
- uncaught runtime exceptions are handled by ending the session
- transport errors (websocket engine) are passed into handleError
WebSocketSession methods may raise IOException
SockJS implementation of WebSocketHandler:
- delegate SockJS transport errors into handleError
- stop runtime exceptions from user WebSocketHandler and end session
SockJsServce and TransportHandlers:
- raise IOException or TransportErrorException
HandshakeHandler:
- raise IOException
HandlerProvider is now an interface that can be used to plug in
WebSocket handlers with per-connection scope semantics. There are two
implementations, of the interface, one simple and a second that creates
handler instances through AutowireCapableBeanFactory.
HandlerProvider also provides a destroy method that is used to
apply a destroy callback whenever a client connection closes.
ASM has been patched to accept 1.8 bytecode simply through removing an assertion. As a consequence, we have an embedded copy of the ASM sources now instead of jarjar'ing the original ASM jar. The sources originate from ASM 4.1; for CGLIB 3.0 compatibility, a further assertion has been removed.

Use LinkedHashMaps/Sets wherever exposed to users, and code tests defensively in terms of expected Map/Set ordering. Otherwise, there'll be runtime order differences between JDK 7 and JDK 8 due to internal HashMap/Set implementation differences.

In particular, avoid accidental usage of ASM for core JDK types - which will fail in case of a new bytecode version in the JDK, even if the application itself has been compiled with an earlier bytecode target.

There is now a WebSocketMessage type with TextMessage and BinaryMessage
sub-types. WebSocketHandler is also sub-divided into TextMessageHandler
and BinaryMessageHandler, so that applications can choose to handle
text, binary, or both.
Also in this commit, the SockJsHandler and SockJsSession interfaces
have been removed. SockJsService now accepts WebSocketHandler.
As opposed to close(), which actively closes the session, the
onClosed method is called when the underlying connection has been
closed or disconnected.
