Before this commit the DefaultUserDestinationResolver did not support
well broker destinations that use dot as separator with a built in
assumptions that the destinations it resolves must start with slash.
This change adds PathMatcher property that is used to determine if
an alternative path separator is in use and if so the leading slash is
left out.

The MultiServerUserRegistry now supports scenarios where the same user
is connected to multiple servers. For such cases the SimpUser returned
from the registry exposes all sessions across all servers.
Issue: SPR-13800
The MessageMethodArgumentResolver now also supports applying a
MessageConverter to the payload.
This is effectively a shortcut for declaring a method with an @Payload
argument + MessageHeaders and then creating a new message from the two.

When the cacheLimit is reached and there is an eviction from the
updateCache, the accessCache is now also updated.
This change also ensures that adding a destination to the cache is
protected with synchronization on the updateCache.
Issue: SPR-13555
AbstractMessageConverter provides overloaded methods with a conversion hint, MappingJackson2MessageConverter takes that hint into account, and SimpMessagingTemplate transformes such a hint in the given headers map into an explicit argument invocation argument.

After SPR-12884 (4.2 RC1) introduced support for a selector header
expression on SUBSCRIBE frames, messages from the destination cache
are further filtered based on the selector expression. While adding a
test to find subscriptions at the same time as unsubscribing, a
potential NPE was exposed. This commit fixes the NPE.

This split avoids a package tangle (between core and core.annotation) and also allows for selective use of raw annotation exposure versus synthesized annotations, with the latter primarily applicable to web and message handler processing at this point.

This commit introduces support for asynchronous return values thanks
to the new AsyncHandlerMethodReturnValueHandler interface. Out of
the box support for ListenableFuture is also provided.
Issue: SPR-12168
This change introduces SimpUserRegistry exposing an API to access
information about connected users, their sessions, and subscriptions
with STOMP/WebSocket messaging. Provides are methods to access users
as well as a method to find subscriptions given a Matcher strategy.
The DefaultSimpUserRegistry implementation is also a
SmartApplicationListener which listesn for ApplicationContext events
when users connect, disconnect, subscribe, and unsubscribe to
destinations.
The MultiServerUserRegistry implementation is a composite that
aggregates user information from the local SimpUserRegistry as well
as snapshots of user on remote application servers.
UserRegistryMessageHandler is used with MultiServerUserRegistry. It
broadcats user registry information through the broker and listens
for similar broadcasts from other servers. This must be enabled
explicitly when configuring the STOMP broker relay.
The existing UserSessionRegistry which was primiarly used internally
to resolve a user name to session id's has been deprecated and is no
longer used. If an application configures a custom UserSessionRegistr
still, it will be adapted accordingly to SimpUserRegistry but the
effect is rather limited (comparable to pre-existing functionality)
and will not work in multi-server scenarios.

This commit introduces a messaging.converter.MessageConverter that
marshals to/from XML using the abstractions provided in the OXM module.
Issue: SPR-12726
This change adds support for broadcasting messages with unresolved
user destinations so that other servers can try to resolve it.
That enables sending messages to users who may be connected to a
different server.
