This commit adds the missing 4.1 XSDs for the following components:
* spring-aop
* spring-context
* spring-jee
* spring-lang
* spring-tx
* spring-util
These are strictly identical to the definition of the 4.0 XSDs.
Issue: SPR-11990
Prior to this commit, an exception thrown by an @Async void method
was not further processed as there is no way to transmit that
exception to the caller.
The AsyncUncaughtExceptionHandler is a new strategy interface that
can be implemented to handle unexpected exception thrown during the
invocation of such asynchronous method.
The handler can be specified using either the XML namespace or by
implementing the AsyncConfigurer interface with the EnableAsync
annotation.

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).

This commit refactors the BeanInfoFactory so that:
- supports() and getBeanInfo() are folded into one, so that getBeanInfo()
returns null if a given class is not supported.
- CachedIntrospectionResults now uses SpringFactoriesLoader
Prior to this change, CachedIntrospectionResults delegated to
ExtendedBeanInfo by default in order to inspect JavaBean
PropertyDescriptor information for bean classes.
Originally introduced with SPR-8079, ExtendedBeanInfo was designed to
go beyond the capabilities of the default JavaBeans Introspector in
order to support non-void returning setter methods, principally to
support use of builder-style APIs within Spring XML. This is a complex
affair, and the non-trivial logic in ExtendedBeanInfo has led to various
bugs including regressions for bean classes that do not declare
non-void returning setters.
This commit takes advantage of the new BeanInfoFactory mechanism
introduced in SPR-9677 to take ExtendedBeanInfo out of the default code
path for CachedIntrospectionResults. Now, the new
ExtendedBeanInfoFactory class will be detected and instantiated (per its
entry in the META-INF/spring.beanInfoFactories properties file shipped
with the spring-beans jar). ExtendedBeanInfoFactory#supports is invoked
for all bean classes in order to determine whether they are candidates
for ExtendedBeanInfo introspection, i.e. whether they declare non-void
returning setter methods.
If a class does not declare any such non-standard setter methods (the
99% case), then CachedIntrospectionResults will fall back to the
default JavaBeans Introspector. While efforts have been made to fix any
bugs with ExtendedBeanInfo, this change means that EBI will not pose
any future risk for bean classes that do not declare non-standard
setter methods, and also means greater efficiency in general.

The following syntax is now supported
<beans profile="p1,!p2">
@Profile("p1", "!p2")
indicating that the <beans> element or annotated component should
be processed only if profile 'p1' is active or profile 'p2' is not
active.
Issue: SPR-8728
Previously, the <value> subelement of a map <entry> allowed one to
specify the type of a specific map entry value. This patch allows a
value-type attribute as well, such that instead of the following
syntax
<entry key="x-message-ttl">
<value type="java.lang.Long">100</value>
</entry>
<entry key="x-ha-policy" value="all" />
one can now use the more concise form
<entry key="x-message-ttl" value="100" value-type="java.lang.Long"/>
<entry key="x-ha-policy" value="all"/>
The new value-type attribute may be used at the <map> level as well,
indicating that all elements are of the same type.
Appropriate tests have been added exercising value-type at the <map> and
<entry> levels.

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.
