Prior to this commit, configuring a custom handshakeHandler when setting
up a stomp-endpoint with SockJS would not be taken into account:
<websocket:stomp-endpoint path="/foo">
<websocket:handshake-handler ref="customHandler"/>
<websocket:sockjs/>
</websocket:stomp-endpoint>
This commit fixes this by creating and registering a
WebsocketTransportHandler (with this handshakeHandler) as a
transportHandler override for the SockJSService.

Prior to this commit, the codebase was using a mix of log4j.xml
and log4j.properties for test-related logging configuration. This
can be an issue as log4j takes the xml variant first when looking
for a default bootstrap configuration.
In practice, some modules declaring the properties variant were
taking the xml variant configuration from another module.
The general structure of the configuration has also been
harmonized to provide a standard console output as well as an
easy way to enable trace logs for the current module.
This commit adds an XML namespace equivalent of @EnableWebSocket and
@EnableWebSocketMessageBroker. Those are <websocket:handlers> and
<websocket:message-broker> respectively.
Examples can be found in the test suite.
This commit also alters the way MessageHandler's subscribe to their
respective MessageChannel's of interest. Rather than performing the
subscriptions in configuration code, the message channels are now
passed into MessageHandler's so they can subscribe themselves on
startup.

The method WsServerContainer.getServerContainer() was removed from
JSR-356 but remained in Tomcat a little while longer. Instead the
ServerContainer is obtained through a ServletContext attribute.
Tomcat has now removed this method, hence the need for this fix.
