Change ContextHierarchyDirtiesContextTests to obtain beans whilst the
ApplicationContext is still open, rather than trying to obtain them
after the context has been closed.

* SPR-10534:
  Add support for DeferredImportSelector
  Support for @Conditional configuration
  Extend AnnotationMetadata and MethodMetadata

Add DeferredImportSelector interface that can be used to select imports
after all @Configuration beans have been processed.

Introduce new @Conditional annotation that can be used to filter
which @Configuration classes or methods are loaded. @Conditional
can be used directly or as a meta-annotation. Condition implementations
are provided via the 'Condition' interface and are free to filter based
on any criteria available at the time that they run. The
ConditionalContext provides access to the BeanDefinitionRegistry,
Environment and ConfigurableListableBeanFactory along with a
ResourceLoader and ClassLoader.

The existing @Profile annotation has been refactored as a @Conditional
with the added benefit that it can now be used as a method level
annotation.

Update AnnotationMetadata and MethodMetadata to extend from a new
AnnotatedTypeMetadata base interface containing the methods that are
common to both. Also introduce new getAllAnnotationAttributes methods
providing MultiValueMap access to both annotation and meta-annotation
attributes.

Existing classreading and standard implementations have been
refactored to support the new interface.

Add PropertySourcesPlaceholderConfigurer.getAppliedPropertySources() to
allow access to the PropertySources that were actually applied.

Allow ClassPathContextResource to be accessed by subclasses of
DefaultResourceLoader.

Issue: SPR-10544

Update ServletContextAwareProcessor to allow subclasses to support late
binding of the ServletConfig and/or ServletContext. Allows for the
post-processor to be registered before the servlet environment has been
initialized.

Issue: SPR-10381

Change FrameworkServlet so that it can also be used as a bean within an
existing ApplicationContext. Primarily added to support use with
embedded servlet containers where Spring bootstraps the servlet
container, rather than the servlet container bootstrapping Spring.

Following the introduction of spring-beans-4.0.xsd and the corresponding removal of the pre-2.0 spring-beans.dtd.

Issue: SPR-10437

Removed spring-beans.dtd (the 1.x variant) and spring-oxm-1.5.xsd (pre-Spring-Framework variant), in order to raise the backwards compatibility limit a little bit at least. We'll keep supporting the 2.0 and 2.5 xsd versions for the time being, as well as spring-beans-2.0.dtd.

Removed the ref 'local' attribute in spring-beans-4.0.xsd since 'local' lost its differentiating role to a regular bean ref back in the 3.1 days when we started allowing for the same bean id to reappear in a different beans section of the same configuration file (with a different profile).

Issue: SPR-10437

Add temporary Assume.canLoadNativeDirFonts() method allowing failing
jasper report tests to be bypassed on OSX.

This should be revisited when JDK 8 is released.

Issue: SPR-10537

Allow classes that are annotated with @Import to be considered as 'lite'
@Configuration candidates. Allows the AnnotationConfigApplicationContext
to directly register @Import beans even if they are not @Components.

Issue: SPR-10533

Exclude self @Component when parsing @ComponentScan annotations.

Issue: SPR-10531

Implementations of Spring's ImportSelector interface may
now implement any of the following *Aware interfaces and have their
respective methods called prior to #registerBeanDefinitions:

 - BeanFactoryAware
 - BeanClassLoaderAware
 - ResourceLoaderAware

Issue: SPR-10530

Add AnnotationConfigApplicationContext constructor allow use of a
custom DefaultListableBeanFactory.

Issue: SPR-10529

Update the SpringFactoriesLoader static loadFactoryNames method from
private to public.

Specifically set the source level in generated eclipse projects to 1.7
rather than 1.8. Allows the current eclipse milestone (4.3 M6) in
combination with JDK 8.0 to be used for Spring 4.0 development.

This commit removes the use of @SuppressWarnings("deprecation") for
code in the spring-test module that no longer references deprecated code.

This commit adds an explicit version to the updated XML configuration
file in order to avoid build errors in IntelliJ IDEA 12.

 - JdkVersion#JAVA_19 is now properly set to 6 instead of 5.
 - Javadoc for getMajorJavaVersion() now references currently supported
   Java versions.

Specifically, we need to avoid "... ? this.method : this.constructor" expressions since those potentially select java.lang.reflect.Executable (which is only available on JDK 8) as common type and hardcode this into the generated bytecode (which therefore becomes JDK 8 dependent).
