- removed generics from Cache/CacheManager (they add no value since it's an SPI not API)
+ update docs and tests
+ renamed ConcurrentCacheFactoryBean to ConcurrentMapCacheFactoryBean

Revert signature of
ConfigurationClassPostProcessor#processConfigBeanDefinitions to its form
found in the 3.0.x line. Refactorings made during 3.1 development
caused otherwise package-private types such as
ConfigurationClassBeanDefinitionReader to escape through this public
method, causing issues for STS as well as being a general design issue.
Upon review, the refactorings could easily be backed out in favor of a
simpler approach, and this has been done.
This also means that ConfigurationClassBeanDefinitionReader can return
to package-private visibility, and this change has been made as well.

A subtle issue existed with the way we relied on isCurrentlyInCreation
to determine whether a @Bean method is being called by the container
or by user code. This worked in most cases, but in the particular
scenario laid out by SPR-8080, this approach was no longer sufficient.
This change introduces a ThreadLocal that contains the factory method
currently being invoked by the container, such that enhanced @Bean
methods can check against it to see if they are being called by the
container or not. If so, that is the cue that the user-defined @Bean
method implementation should be invoked in order to actually create
the bean for the first time. If not, then the cached instance of
the already-created bean should be looked up and returned.
See ConfigurationClassPostConstructAndAutowiringTests for
reproduction cases and more detail.

If the enclosing environment does not implement ConfigurableEnvironment,
then @PropertySource annotations are ignored because there is no way to
add them to the Environment. Now checking first to see if there are any
@PropertySource annotations present before issuing the warning.

Users may now call #setRequiredProperties(String...) against the
Environment (via its ConfigurablePropertyResolver interface) in order
to indicate which properties must be present.
Environment#validateRequiredProperties() is invoked by
AbstractApplicationContext during the refresh() lifecycle to perform
the actual check and a MissingRequiredPropertiesException is thrown
if the precondition is not satisfied.

Declaring @Bean methods as 'static' is now permitted, whereas previously
it raised an exception at @Configuration class validation time.
A static @Bean method can be called by the container without requiring
the instantiation of its declaring @Configuration class. This is
particularly useful when dealing with BeanFactoryPostProcessor beans,
as they can interfere with the standard post-processing lifecycle
necessary to handle @Autowired, @Inject, @Value, @PostConstruct and
other annotations.
static @Bean methods cannot recieve CGLIB enhancement for scoping and
AOP concerns. This is acceptable in BFPP cases as they rarely if ever
need it, and should not in typical cases ever be called by another
@Bean method. Once invoked by the container, the resulting bean will
be cached as usual, but multiple invocations of the static @Bean method
will result in creation of multiple instances of the bean.
static @Bean methods may not, for obvious reasons, refer to normal
instance @Bean methods, but again this is not likely a concern for BFPP
types. In the rare case that they do need a bean reference, parameter
injection into the static @Bean method is technically an option, but
should be avoided as it will potentially cause premature instantiation
of more beans that the user may have intended.
Note particularly that a WARN-level log message is now issued for any
non-static @Bean method with a return type assignable to BFPP. This
serves as a strong recommendation to users that they always mark BFPP
@Bean methods as static.
See @Bean Javadoc for complete details.

Prior to this change, @ComponentScan annotations were only processed at
the first level of depth. Now, the set of bean definitions resulting
from each declaration of @ComponentScan is checked for configuration
classes that declare @ComponentScan, and recursion is performed as
necessary.
Cycles between @ComponentScan declarations are detected as well. See
CircularComponentScanException.

Introduce @EnableAsync#order
AsyncAnnotationBeanPostProcessor's 'order' property is now mutable;
@EnableAsync's 'order()' attribute allows for setting it, but must
have a default value, thus uses the new Ordered#NOT_ORDERED
constant - a reserved negative number very unlikely to be otherwise
used that may be interpreted as 'not ordered', useful in annotation
defaulting scenarios where null is not an option.
Introduce first working cut of AsyncConfiguration

This change is in support of certain polymorphism cases in
@Configuration class inheritance hierarchies. Consider the following
scenario:
@Configuration
public abstract class AbstractConfig {
public abstract Object bean();
}
@Configuration
public class ConcreteConfig {
@Override@Bean
public BeanPostProcessor bean() { ... }
}
ConcreteConfig overrides AbstractConfig's #bean() method with a
covariant return type, in this case returning an object of type
BeanPostProcessor. It is critically important that the container
is able to detect the return type of ConcreteConfig#bean() in order
to instantiate the BPP at the right point in the lifecycle.
Prior to this change, the container could not do this.
AbstractAutowireCapableBeanFactory#getTypeForFactoryMethod called
ReflectionUtils#getAllDeclaredMethods, which returned Method objects
for both the Object and BeanPostProcessor signatures of the #bean()
method. This confused the implementation sufficiently as not to
choose a type for the factory method at all. This means that the
BPP never gets detected as a BPP.
The new method being introduced here, #getUniqueDeclaredMethods, takes
covariant return types into account, and filters out duplicates,
favoring the most specific / narrow return type.
Additionally, it filters out any CGLIB 'rewritten' methods, which
is important in the case of @Configuration classes, which are
enhanced by CGLIB. See the implementation for further details.

Consolidating internal bean name and aspect class name constats within
AnnotationConfigUtils to allow access from both the context.config
and context.annotation packages without creating a relationship between
the two of them (they are unrelated leaf nodes in the packaging
currently).
The .transaction module does not have a similar utils class and already
has a relationship from transaction.config -> transaction.annotation,
so placing the constants in .annotation.TransactionManagementCapability
to be referenced by .config.AnnotationDrivenBeanDefinitionParser
