This commit adds a "spring-context-indexer" module that can be added to
any project in order to generate an index of candidate components defined
in the project.
`CandidateComponentsIndexer` is a standard annotation processor that
looks for source files with target annotations (typically `@Component`)
and references them in a `META-INF/spring.components` generated file.
Each entry in the index is the fully qualified name of a candidate
component and the comma-separated list of stereotypes that apply to that
candidate. A typical example of a stereotype is `@Component`. If a
project has a `com.example.FooService` annotated with `@Component` the
following `META-INF/spring.components` file is generated at compile time:
```
com.example.FooService=org.springframework.stereotype.Component
```
A new `@Indexed` annotation can be added on any annotation to instructs
the scanner to include a source file that contains that annotation. For
instance, `@Component` is meta-annotated with `@Indexed` now and adding
`@Indexed` to more annotation types will transparently improve the index
with additional information. This also works for interaces or parent
classes: adding `@Indexed` on a `Repository` base interface means that
the indexed can be queried for its implementation by using the fully
qualified name of the `Repository` interface.
The indexer also adds any class or interface that has a type-level
annotation from the `javax` package. This includes obviously JPA
(`@Entity` and related) but also CDI (`@Named`, `@ManagedBean`) and
servlet annotations (i.e. `@WebFilter`). These are meant to handle
cases where a component needs to identify candidates and use classpath
scanning currently.
If a `package-info.java` file exists, the package is registered using
a "package-info" stereotype.
Such files can later be reused by the `ApplicationContext` to avoid
using component scan. A global `CandidateComponentsIndex` can be easily
loaded from the current classpath using `CandidateComponentsIndexLoader`.
The core framework uses such infrastructure in two areas: to retrieve
the candidate `@Component`s and to build a default `PersistenceUnitInfo`.
Rather than scanning the classpath and using ASM to identify candidates,
the index is used if present.
As long as the include filters refer to an annotation that is directly
annotated with `@Indexed` or an assignable type that is directly
annotated with `@Indexed`, the index can be used since a dedicated entry
wil be present for that type. If any other unsupported include filter is
specified, we fallback on classpath scanning.
In case the index is incomplete or cannot be used, The
`spring.index.ignore` system property can be set to `true` or,
alternatively, in a "spring.properties" at the root of the classpath.

Move spring-webmvc-tiles3 content to spring-webmvc, and
create a spring-webmvc-tiles2 module with Tiles 2 support.
Its allows View Resolution to configure Tiles 3 instead of Tiles 2.

Move code from spring-build-junit into spring-core/src/test along with
several other test utility classes. This commit removes the temporary
spring-build-junit project introduced in commit
b083bbdec7.
Introduce new 'spring-build-junit' subproject containing shared
JUnit utilities and classes to be used by other test cases. This
project is for internal use within the framework, and therefore
creates no artifacts to be published to any repository.
The initial code includes support for JUnit Assumptions that can
be used to determine when a test should run. Tests can be skipped
based on the running JDK version, logging level or based on specific
'groups' that have activated via a Gradle property.
It is intended that sources within the spring-build-junit project be
folded into spring-core/src/test/java, pending some Gradle work that
will facilitate sharing test output across subprojects; therefore this
commit should be seen as a temporary solution.

Previously reflection was required when interacting with Hibernate 4 in
order to support both Hibernate 3 and Hibernate 4 since there were
non-passive changes in the APIs. Now that the Spring build uses Gradle
it is trivial to support multiple Hibernate versions.
This commit removes the reflection usage in orm.hibernate4.* by
creating a spring-orm-hibernate4 module that uses
gradle/merge-artifacts.gradle to build a single artifact but keep
distinct classpaths.

Tiles 3 has modified packages and classes as well as additional
dependencies, notably "tiles-request-api", which is a request/response
abstraction independent of Servlet and JSP APIs.
In order to have both Tiles 2 and Tiles 3 integrations, the source for
the Tiles 3 integration is in a separate project spring-webmvc-tiles3.
The build process merges the compiled Tiles 3 integration classes into
the spring-webmvc module so in effect it contains both the Tiles 2 and
the Tiles 3 integrations.
This change originated as a pull request at spring-framework-issues:
https://github.com/SpringSource/spring-framework-issues/pull/30

This commit adds the spring-test-mvc project [1] to the Spring
Framework as part of the spring-test module.
The sources are added as a root-level project called "spring-test-mvc"
instead of under "spring-test" because the new sources need to be
compiled with Servlet 3 while the current "spring-test" sources require
Servlet 2.5 and the Eclipse IDE does not support having different
classpaths for the same project.
The Gradle build produces a single spring-test jar that contains
sources from both "spring-test" and "spring-test-mvc". This merge is
made possible through merge-dist.gradle as follows:
- jar tasks of the "from" project execute tasks of the "to" project
- "to" project is added to the classpath of the "from" project
- "to" project pom is updated with entries from the "from" project
For further details see documentation in merge-dist.gradle.

Issue: SPR-9859, SPR-7951
ASM 4.0 is generally compatibile with Java 7 classfiles, particularly
including 'invokedynamic' instructions. This is important when
considering that Spring's component-scanning support is internally
ASM-based and it is increasingly likely that component classes having
invokedynamic instructions may be encountered and read by ASM.
This upgrade, then, is primarily preventive in nature.
Changes include:
- upgrade from ASM 2.2.3 to ASM 4.0
- adapt to ASM API changes as necessary throughout spring-core,
resulting in no impact to the public Spring API.
- remove dedicated spring-asm module
- use new :spring-core:asmRepackJar task to repackage
org.objectweb.asm => org.springframework.asm as per usual and write
repackaged classes directly into spring-core jar
The choice to eliminate the spring-asm module altogether and instead
inline the repackaged classes directly into spring-core is first to
eliminate an otherwise unnecessary second jar. spring-core has a
non-optional dependency on spring-asm meaning it is always on the
application classpath. This change simplifies that situation by
consoliding two jars into one. The second reason for this choice is in
anticipation of upgrading CGLIB to version 3 and inlining it into
spring-core as well. See subsequent commit for details.

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.

This commit eliminates the 'integration-tests' subproject in favor of
managing these sources under the root project's own 'src' directory.
This helps to avoid special-case handling for integration-tests in the
Gradle build, e.g. avoiding publication of jars to Artifactory /
Maven Central.
It is also semantically more correct. This is not a Spring Framework
subproject so much as it is a collection of integration tests that
span functionality across many subprojects. In this way, it makes
sense to place them directly under the root project.
