The overloading necessary to preserve the new signature as well as
the old causes ambiguities leading to deprecation warnings in some
caller scenarios.

Issue: SPR-7901

Introduced to support checking return types on @Bean methods but never
actually used.  May be reintroduced as necessary in the future.

Reflecting signature changes in getProperty() methods

- Removed AbstractGenericContextLoader's createGenericApplicationContext() method.
- AnnotationConfigContextLoader now uses an AnnotatedBeanDefinitionReader instead of working with an AnnotationConfigApplicationContext.
- AnnotationConfigContextLoader now uses the supplied GenericApplicationContext to load configuration classes.

Resolve custom args after annotated args, set PATH_WITHIN_HANDLER_MAPPING attribute, and rename resolver for @ExceptionHandler methods

SessionFactory objects created by
SessionFactoryBuilderSupport#buildSessionFactory are now DisposableBean
proxies that call SessionFactory#close and release any threadlocal
DataSource object.

This is the same behavior that has always occurred during LSFBean and
ASFBean destruction lifecycles (and still does). This destruction logic
has now been factored out into
SessionFactoryBuilderSupport#closeHibernateSessionFactory such that all
SFB types can reuse it easily.

Note that LSFBean and ASFBean are subclasses, respectively, of SFBuilder
and ASFBuilder and they each must disable the DisposableBean proxying in
order to avoid duplicate attempts at closing the SessionFactory. See
the implementations of wrapSessionFactoryIfNeccesary() for details.
