Make @Configuration classes thread-safe

Browse Source 
Refactor ConfigurationClassEnhancer so that BeanFactory instances are
not held against CGLIB Callback objects. Enhanced @Configuration classes
now use the BeanFactoryAware interface in order to obtain a BeanFactory.

This change has the additional benefit that a static final field can
now be used to hold all Callback instances.
