Introduce annotation to execute SQL scripts in the TCF

Prior to this commit, it was possible to execute SQL scripts
programmatically via ResourceDatabasePopulator, JdbcTestUtils, and
ScriptUtils. Furthermore, it was also possible to execute SQL scripts
declaratively via the <jdbc> XML namespace. However, it was not
possible to execute SQL scripts declaratively on a per test class or
per test method basis.

This commit makes it possible to declaratively configure SQL scripts
for execution in integration tests via annotations that can be declared
at the class or method level. Details follow.

 - Introduced a repeatable @DatabaseInitializer annotation that can be
   used to configure SQL scripts at the class or method level with
   method-level overrides. @DatabaseInitializers serves as a container
   for @DatabaseInitializer.

 - Introduced a new DatabaseInitializerTestExecutionListener that is
   responsible for parsing @DatabaseInitializer and
   @DatabaseInitializers and executing SQL scripts.

 - DatabaseInitializerTestExecutionListener is registered by default in
   abstract base test classes as well as in TestContextBootstrapper
   implementations.

 - @DatabaseInitializer and @DatabaseInitializers may be used as
   meta-annotations; however, attribute overrides are not currently
   supported for repeatable annotations used as meta-annotations. This
   is a known limitation of Spring's AnnotationUtils.

 - The semantics for locating SQL script resources is consistent with
   @ContextConfiguration's semantics for locating XML configuration
   files. In addition, a default SQL script can be detected based
   either on the name of the annotated class or on the name of the
   annotated test method.

 - @DatabaseInitializer allows for specifying which DataSource and
   PlatformTransactionManager to use from the test's
   ApplicationContext, including default conventions consistent with
   TransactionalTestExecutionListener and @TransactionConfiguration.

 - @DatabaseInitializer supports all of the script configuration options
   currently supported by ResourceDatabasePopulator.

 - @DatabaseInitializer and DatabaseInitializerTestExecutionListener
   support execution phases for scripts that dictate when SQL scripts
   are executed (i.e., before or after a test method).

 - SQL scripts can be executed within the current test's transaction if
   present, outside of the current test's transaction if present, or
   always in a new transaction, depending on the value of the boolean
   requireNewTransaction flag in @DatabaseInitializer.

 - DatabaseInitializerTestExecutionListener delegates to
   ResourceDatabasePopulator#execute to actually execute the scripts.

  Fix a typo

This commit introduces OrderProvider and OrderProviderComparator, two
interfaces designed to externalize how a collection of element is sorted
according to their order value.

FactoryAwareOrderProvider is an OrderProvider implementation that knows
about the objects to order and the corresponding BeanFactory instance.
This allows to retrieve additional metadata about the actual instances
to sort, such as its factory method.

A @Bean method can now holds an additional @order to define the order
value that this bean should have when injected as part of a collection
or array.

Prior to this commit, the ordering of classpath entries in the
generated Eclipse .classpath files did not align with the intended
dependency management configured in the Gradle build. Specifically,
project dependencies often came before dependencies on third-party
libraries required for the given project, causing the project not to
compile in Eclipse.

This commit fixes this issue by introducing new functionality in the
ide.gradle script that moves all project dependencies to the end of the
generated classpath.

Eclipse 4.4 early release versions have issues with generics.

This commit slightly tweaks the use of generics in
JmsMessagingTemplateTests so that the class compiles in the latest
builds of Eclipse 4.4

This change adds a ResourceTransformer that can be invoked in a chain
after resource resolution. The CssLinkResourceTransformer modifies a
CSS file being served in order to update its @import and url() links
(e.g. to images or other CSS files) to match the resource resolution
strategy (e.g. adding MD5 content-based hashes).
