Add ResponseBodyInterceptor

This change introduces a new ResponseBodyInterceptor interface that can
be used to modify the response after @ResponseBody or ResponseEntity
methods but before the body is actually written to the response with the
selected HttpMessageConverter.

The RequestMappingHandlerAdapter and ExceptionHandlerExceptionResolver
each have a property to configure such interceptors. In addition both
RequestMappingHandlerAdapter and ExceptionHandlerExceptionResolver
detect if any @ControllerAdvice bean implements ResponseBodyInterceptor
and use it accordingly.

Refactor @JsonView support w/ ResponseBodyInterceptor

The newly added support for ResponseBodyInterceptor is a good fit for
the (also recently added) support for the Jackson @JsonView annotation.

This change refactors the original implementation of @JsonView support
for @ResponseBody and ResponseEntity controller methods this time
implemented as an ResponseBodyInterceptor.
