This commit moves JmsHandlerMethodFactory and its default
implementation to the messaging abstraction. Working on a similar
support for AMQP revealed that this factory has nothing that is JMS
specific and is exactly identical in the case of AMQP.

Prior to this commit, customizing the concurrency to use fo a given JMS
listener involved to define it in a specific listener-container. As
this is quite restrictive, users may stop using the XML namespace
support altogether to fallback on regular abstract bean definition for
the container.
This commit adds a concurrency attribute to the jms and jca listener
element as well as on the @JmsListener annotation. If the value is set,
it takes precedence; otherwise the value provided by the factory is
used.

This commit separates the BackOff configuration from an actual
execution. BackOffExecution now contains all the state of a
particular execution and BackOff is only meant to start (i.e.
create) a new execution.
The method "reset" has been removed as its no longer necessary:
when an execution does not need to be used for a given operation
anymore it can be simply discarded.
Issue: SPR-11746
This commit adds a "back-off" attribute to the jms:listener-container
element so that a BackOff instance can be provided for users of the
XML namespace.

Prior to this commit, the default JmsListenerContainerFactory to use
must be explicitly set. Since having a single container factory is a
fairly common use case, we look up the default one automatically
using the bean name "jmsListenerContainerFactory".
It is still possible to provide an explicit default but since it refers
more to "the" container factory to use, the parameter has been
renamed to "containerFactory" which is shorter and more explicit.
The lookup strategy is lazy: if all endpoints are providing an
explicit container factory and no container factory with the
"jmsListenerContainerFactory" bean name exists, no exception
will be thrown.

This commit adds the support of JMS annotated endpoint. Can be
activated both by @EnableJms or <jms:annotation-driven/> and
detects methods of managed beans annotated with @JmsListener,
either directly or through a meta-annotation.
Containers are created and managed under the cover by a registry
at application startup time. Container creation is delegated to a
JmsListenerContainerFactory that is identified by the containerFactory
attribute of the JmsListener annotation. Containers can be
retrieved from the registry using a custom id that can be specified
directly on the annotation.
A "factory-id" attribute is available on the container element of
the XML namespace. When it is present, the configuration defined at
the namespace level is used to build a JmsListenerContainerFactory
that is exposed with the value of the "factory-id" attribute. This can
be used as a smooth migration path for users having listener containers
defined at the namespace level. It is also possible to migrate all
listeners to annotated endpoints and yet keep the
<jms:listener-container> or <jms:jca-listener-container> element to
share the container configuration.
The configuration can be fine-tuned by implementing the
JmsListenerConfigurer interface which gives access to the registrar
used to register endpoints. This includes a programmatic registration
of endpoints in complement to the declarative approach. A default
JmsListenerContainerFactory can also be specified to be used if no
containerFactory has been set on the annotation.
Annotated methods can have flexible method arguments that are similar
to what @MessageMapping provides. In particular, jms listener endpoint
methods can fully use the messaging abstraction, including convenient
header accessors. It is also possible to inject the raw
javax.jms.Message and the Session for more advanced use cases. The
payload can be injected as long as the conversion service is able to
convert it from the original type of the JMS payload. By
default, a DefaultJmsHandlerMethodFactory is used but it can be
configured further to support additional method arguments or to
customize conversion and validation support.
The return type of an annotated method can also be an instance of
Spring's Message abstraction. Instead of just converting the payload,
such response type allows to communicate standard and custom headers.
The JmsHeaderMapper infrastructure from Spring integration has also
been migrated to the Spring framework. SimpleJmsHeaderMapper is based
on SI's DefaultJmsHeaderMapper. The simple implementation maps all
JMS headers so that the generated Message abstraction has all the
information stored in the protocol specific message.

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).
Issue: SPR-10437
Copy spring-*-3.1.xsd => spring-*-3.2.xsd; this commit introduces no
substantive changes, but rather prepares for them by creating a clean
baseline. All internal references to 3.1 schemas (e.g. spring-tool) have
also been updated.
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.
