This commit introduces a test in XmlBeanFactoryTests that verifies that
CGLIB generated subclasses for method injected beans are reused across
bean factories for identical bean definitions. In other words, by
verifying that the same CGLIB generated class is reused for identical
bean definitions, we can be certain that Spring is no longer generating
identical, duplicate classes that consume memory in the VM.

Issue: SPR-10785, SPR-11420

Specifically, if the current factory has Qualifier/ContextAnnotationAutowireCandidateResolver set up, it is important to pass it on to ancestor factories to get consistent qualifier matching results.

Issue: SPR-10966

Fixed inner bean name determination for multi-level nesting scenario, calculating a unique bean name as early as possible now (and for any kind of bean scope)

Our per-bean caching in AutowiredAnnotationBeanPostProcessor and co relies on unique bean names, so this change fixes potential cache mismatch problems occuring there.

Also fixing an old XmlBeanFactory test that relies on "ref local" which is gone in the 4.0 xsd now, redeclaring the affected file to an older xsd version.

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).

Prior to this commit many test utility classes and sample beans were
duplicated across projects. This was previously necessary due to the
fact that dependent test sources were not shared during a gradle
build. Since the introduction of the 'test-source-set-dependencies'
gradle plugin this is no longer the case.

This commit attempts to remove as much duplicate code as possible,
co-locating test utilities and beans in the most suitable project.
For example, test beans are now located in the 'spring-beans'
project.

Some of the duplicated code had started to drift apart when
modifications made in one project where not ported to others. All
changes have now been consolidated and when necessary existing tests
have been refactored to account for the differences.

Fix deprecation compiler warnings by refactoring code or applying
@SuppressWarnings("deprecation") annotations. JUnit tests of
internally deprecated classes are now themselves marked as
@Deprecated.

Numerous EasyMock deprecation warnings will remain until the
migration to mockito can be completed.

Issue: SPR-10129

All warning types other than [deprecation] and [unchecked] are now
fixed in spring-context/src/test

 - Suppress rawtypes warnings for src/main
 - Enable rawtypes warnings for src/test

This commit attempts to to resolve all rawtypes problems across tests as
aggressively as possible, i.e. without regard for binary compatibility,
whereas main sources must be treated much more cautiously with an eye
toward compatibility.

Fix serialization warnings by applying @SuppressWarnings("serial")
when appropriate.

In certain cases and for unknown reasons, a correctly-placed
@SuppressWarnings("serial") annotation will fix the warning at the
javac level (i.e. the Gradle command-line), but will produce an
"unnecessary @SuppressWarnings" warning within Eclipse. In these
cases, a private static final serialVersionUID field has been added
with the default value of 1L.

Issue: SPR-10107

Allow the body of 'arg-type' XML elements to be used as an alternative to
'match' attribute when defining a 'replace-method' in XML configuration.

This change has been introduced primarily to support the samples printed
in the Apress 'Pro Spring' book.

This renaming more intuitively expresses the relationship between
subprojects and the JAR artifacts they produce.

Tracking history across these renames is possible, but it requires
use of the --follow flag to `git log`, for example

    $ git log spring-aop/src/main/java/org/springframework/aop/Advisor.java

will show history up until the renaming event, where

    $ git log --follow spring-aop/src/main/java/org/springframework/aop/Advisor.java

will show history for all changes to the file, before and after the
renaming.
