This commit refines getMergedBeanDefinition's scope adaptation algorithm for inner beans, never leaving a custom scope within a containing bean of a different scope. The inner bean's scope will either be aligned with the containing bean's scope (matching the effective state) or be switched to prototype in case of an outer singleton (indicating that no singleton state management is desired).
Issue: SPR-13739
The Javadoc wrongly referred to a behaviour that is not (and should not
be) implemented. List items are split into indexed keys and the
comma-separated value is not retained.

This commit migrates all remaining tests from JUnit 3 to JUnit 4, with
the exception of Spring's legacy JUnit 3.8 based testing framework that
is still in use in the spring-orm module.

Commit 3d86f15 added a lot of new feature in AbstractPropertyAccessor
shared by both DirectFieldAccessor and BeanWrapperImpl. This makes this
abstract class harder to implement for others having simpler use cases.
It turns that Spring Data has such use case; this commit split these new
features in a dedicated new base class, leaving AbstractPropertyAccessor
untouched.
Issue: SPR-12805
Previously, the binding may have to call the getter first to retrieve the
old value of a property before actually setting it. This was guarded by
a catch block that was accidentally removed in 3d86f15
Restore that catch block and add a test to cover it.

`BeanWrapperImpl` and `DirectFieldAccessor` are two
`ConfigurablePropertyAccessor` implementations with different features
set.
This commit harmonizes the two implementations to use a common base class
that delegates the actual property handling to the sub-classes:
* `BeanWrapperImpl`: `PropertyDescriptor` and introspection utilities
* `DirectFieldAccessor`: reflection on `java.lang.Field`
Issues: SPR-12206 - SPR-12805
Covers ReflectionUtils.doWithMethods as well as affected annotation post-processors.
Includes an extension of MethodMetadata for the detection of @Bean default methods.

Issue: SPR-10919
Previously, only indexed access for collections were supported. When
attempting to access the element of an array that had not the requested
size, the call would fail with an IndexOutOfBoundException
This commit harmonize the binding support so that the array is updated
according to the requested index if necessary.
