@Configuration classes may implement ImportAware in order to be injected
with the AnnotationMetadata of their @Import'ing class.

Includes the introduction of a new PriorityOrdered
ImportAwareBeanPostProcessor that handles injection of the
importing class metadata.

@Primary/@Lazy/@DependsOn supported as meta-annotations; @Bean supported as meta-annotation on factory methods as well

custom stereotype annotations can be meta-annotated with @Service, @Controller etc as well; @Scope and @Transactional are now supported as meta-annotations on custom annotations

revised support for annotated factory methods (merged @FactoryMethod functionality into JavaConfig facility)

+ Added tests for @Aspect support in @Configuration classes
+ Added tests for @Inherited @Configuration behavior

+ Consolidated all remaining supporting classes into .support package, eliminating .internal.*
+ 7 public types remain

+ Eliminated @ScopedProxy in favor of @Scope(proxyMode=NO|INTERFACES|TARGET_CLASS)

+ Eliminated UsageError/Validatable/MalformedConfigurationException in favor of existing Problem/ProblemReporter types
+ Pruned a number of attributes from the @Bean and @Configuration annotations
