BufferingMessageSender: Split uncork() and drain().

We actually want to send messages *out of order*; the create_surface reply first,
*then* the buffered messages (which possibly reference that surface).

To do this we need to first uncork(), so that the reply can be sent, *then* drain(),
sending any events that were buffered up.

Examples: Pass the surface-builder function through to generate_decorations_for

Because we do the simplest possible thing and use a full-fat BasicSurface for the example
decorations we should build it correctly; that's what the build function is for.

Ensure correct ordering of surface events.

Ensure that no surface events are sent before the create_surface reply is sent,
instead buffer them up and send them just after the create_surface reply.

Provide a Surface's EventSink directly from SessionMediator on create_surface

Plumb an EventSinkFactory through to SessionMediator.

SessionMediator will use this to create Surface event sinks.

Test that messages sent after uncork() are dispatched.

Add a BufferingMessageSender implementation.

This adapts another MessageSender, queuing up all messages internally until
uncork() is called and then transparently sending to the underlying
MessageSender.
