Introduce @EnableMBeanExport

Add support for @EnableMBeanExport annotation allowing @Configuration
classes to easily export all MBeans and @ManagedResources from the
Spring application context. The annotation is functionally equivalent
to the XML <context:mbean-export/> element.

Allow setting WSDL document as a Resource

Prior to this change, LocalJaxWsServiceFactory allowed specifying a WSDL
document URL. Now users may also specify a WSDL document represented as
a Spring Resource object for convenience.

Fix split package introduced by @EnableSpringConfigured

Commit 5327a7a37d25b67ee2ae7d1ead2a3db6847767c0 moved
@EnableSpringConfigured from beans.factory.aspectj =>
context.annotation within the spring-aspects module. This resolved a
package cycle but had the side-effect of causing a "split package" [1]
problem between spring-context and spring-aspects in OSGi-based
classloader environments because the context.annotation package now
exists in both modules.

The simplest and best solution from an OSGi perspective is to relocate
@EnableSpringConfigured and its supporting SpringConfiguredConfiguration
class into a new package. This commit moves both these types into
context.annotation.aspectj, following convention with other such
"aspectj"-qualified packages in the spring-aspects module.

As with the previous move, it is presumed this change will be low-impact
as the "spring-configured" approach to domain object injection is a
niche feature to begin with, and @EnableSpringConfigured has existed in
its current location only since 3.1.2 and this change is being made in
time for 3.1.3.

Fix package cycle in @EnableMBeanExport

Prior to this commit, @EnableMBeanExport was declared in the
jmx.export.annotation package. This makes logical sense, but
nevertheless creates a package cycle, because @EnableMBeanExport depends
on MBeanExportConfiguration which in turn depends on context.annotation
types like @Configuration, @Bean, and @Role.

context.annotation.config.MBeanExportBeanDefinitionParser, on the other
hand already has dependencies on types in jmx.support. Together, this
means that a package cycle was introduced.

The solution to this is simple: move @EnableMBeanExport and friends from
jmx.export.annotation => context.annotation. This has been the strategy
for other @Enable annotations and for the same reasons. It also makes a
kind of logical sense: just like you find <context:mbean-export> and
<context:load-time-weaver> under the context: XML namespace, so too do
you find their @Enable* counterparts under the context.annotation
namespace.

Filter @Configuration classes out of LTW test

Moving @EnableMBeanExport and its MBeanExportConfiguration
@Configuration class into context.annotation caused a side effect with
ComponentScanningWithLTWTests, which component scans context.annotation
in order to test LTW behavior. Picking up MBeanExportConfiguration
without proper MBean configuration resulted in a NullPointerException
during test execution.

This commit simply filters out all @Configuration classes from the LTW
test's component-scanning directive.
