After this change, annotated message handling methods configured to use
a destination prefix (e.g. "/app") no longer have to include the prefix
in their mapping. For example if a client sends a message to "/app/foo"
the annotated methods should be mapped with @MessageMapping("/foo").

Added "target-package" to the jibx-marshaller element. Also fixed "context-path" and "binding-name" to follow Spring's usual attribute naming convention.

Also exposing "getPoolSize()" and "getActiveCount()" from ThreadPoolTaskScheduler now, analogous to ThreadPoolTaskExecutor.

Issue: SPR-10883

Also internally renaming SimpleNonIndexedPropertyDescriptor to SimplePropertyDescriptor and preferring direct field access wherever possible.

Changed return values of Future<Void> to Future<?> in AsyncRestTemplate
and AsyncRestOperations.

Ensure configuration provided for WebSocketHandler's (eg interceptors,
or HandshakeHandler) are passed on to the SockJsService if congiured.

Better separate Servlet-specific parts of the configuration to make it
more obvious where non-Servlet alternatives could fit in.

Add more tests.

Improve WebSocket integration tests.

Previously, the negotiated version was included in the CONNECTED frame
using the accept-version header. This is incorrect. The version
header should be used.

* pull304:
  Assign lowest priority to `/**` pattern

Update AntPathMatcher Comparator to treat `/**` in the same way as
`null` paths.

Prior to this commit the pattern `/**` would be picked in preference
to patterns with 3 or more PathVariable (e.g. `/matches/{matchId}/
periods/{periodId}/teams/{teamId}/results`).

Issue: SPR-10550

Refine AntPathMatcher.combine rules to allow direct concatenation of
patterns when pattern1 does not contain '*.'. Prior to this commit
direct concatenation was allowed when pattern1 did not contain '.',
this prevented calls of the form:

	pathMatcher.combine("/1.0", "/foo/test")

from working as expected.

This commit also applies some general cleanup to the `combine` method.

@Bean methods are allowed to override existing bean definitions with a role other than ROLE_APPLICATION now (e.g. framework-generated default beans)

Also, DefaultListableBeanFactory logs a warning when overriding an application definition with a framework-generated definition now, which is expected to be an accident.
