+ If a user provided config is supplied, then that config should
be used for init(EndpointConfig) and other various accesses to
the configuration object. This refactor stops using an internal
EndpointConfig object always and moves the internal config
fields into the JsrSession object instead.
+ Refactored websocket-commons Session creation to be factory based
+ Introduced new org.eclipse.jetty.websocket.common.SessionFactory
+ Made websocket-client and websocket-server use new SessionFactory
+ Introduced JsrSessionFactory to allow for consistent Session creation
even in the Jsr (no more duplciate Session creation)
+ Using JsrSessionFactory in javax-websocket-client-impl
+ Introducing PathMappings to hopefully replace jetty-util's PathMap
+ Using standard ClientEndpointConfig when appropriate.
+ Introducing JettyClientEndpointConfig for annotation based
configurations
+ Renaming EchoSocket used in javax.websocket client testing to
JettyEchoSocket to better indicate that its the Jetty server side
implementation and not the javax.websocket client side socket.
+ Changed IncomingFrames.incomingError() parameter from
WebSocketException to Throwable to match behavior on the JSR
