Add default ViewResolver to MVC Java config

Since the MVC Java config always registers a ViewResolver (composite)
bean, at a very minimum we must add an InternalResourceViewResolver
consistent with default DispatcherServlet configuration and by
extension with the MVC namespace which falls back on DispatcherServlet
implicity if no <view-resolvers> element is present.

Enhance ParameterizableViewController

This change two new capabilities to ParameterizableViewController:

 - configure a View instance (in addition to view name)
 - configure response status code

The status code may be useful to send a 404 while also writing to the
body using a view.

The status code may also be used to override the redirect status code
of RedirectView. Even today it's possible to configure a "redirect:"
prefixed view name but the status code could not be selected. When a
3xx status is set, the code is passed on to the RedirectView while the
view name is automatically prefixed with "redirect:" (if not already).

For full control over RedirectView it is now also possible to
parameterize the controller with a View instance.

As one more possible resulting variation, given status 204 and no view
the request is considered handled (controller returns null).

This change is preparation for SPR-11543.
Add propagateQueryParams property to RedirectView

This change makes it possible to configure RedirectView such that the
query string of the current request is added to the target URL.

This change is preparation for SPR-11543.
Enhance view controller MVC config

This change adds support for configuring redirect view controllers and
also status controllers to the MVC Java config and the MVC namespace.
