Regarding this JIRA issue:
- http://jira.jboss.com/jira/browse/JBMICROCONT-277

I've added this

 /**
 * Get bean validator bridge.
 *
 * @param context the owner context
 * @return bean validator instance if exists, null otherwise
 */
 static BeanValidatorBridge getBeanValidatorBridge(KernelControllerContext context)
 {
 Controller controller = context.getController();
 ControllerContext validator = controller.getInstalledContext(BeanValidatorBridge.class);
 return validator != null ? BeanValidatorBridge.class.cast(validator.getTarget()) : null;
 }

a way to get the bridge between jsr303 and our MC code.

I've then added hooks into
- InstantiateAction (constructor and instantiation validation)
- PropertyDispatchWrapper (property injection)
- AbstractKernelControllerContext (method invocation)

Once I'm (+ hopefully getting Emmanuel to chip in) done with jsr303, I'll implement a proper bridge, which we can simply drop into Controller.
