Add naming strategy for @MVC request mappings.

This change adds a strategy for assigning a default name to an
@RequestMapping controller method. The @RequestMapping annotation
itself now has a name attribute allowing the explicit assignment
of a mapping name.

This is mainly intended for use in EL expressions in views. The
RequestContext class now provides a getMvcUrl method that internally
delegates to MvcUriComponents to look up the handler method.

See the Javadoc of MvcUriComponents.fromMappingName.

Support path segment URI var expansion in UrlTag

Before this change UrlTag expanded URI vars and encoded them using
UriUtils.encodePath.

This change makes it possible to expand using
UriUtils.encodePathSegment, which means a "/" is encoded as "%2F".

To expand with path segment semantics, prefix the URI var name "/":

<spring:url value="/url/path/{/var}">
    <spring:param name="var" value="my/Id" />
</spring:url>

Avoid ConcurrentModificationException

Removal of cached destination is now moved outside the for loop
that removes subscriptions to avoid ConcurrentModificationException.

Also since updateCache is a LinkedHashMap with accessOrder=true,
a simple access with updateCache.get() modify the map.
By iterating over updateCache.entrySet(), we avoid this update.

Allow use of @SendToUser even w/o authenticated user

Before this change, subscribing to a user destination and use of
@SendToUser annotation required an authenticated user.

This change makes it possible to subscribe to a user destination from
WebSocket sessions without an authenticated user. In such cases the
destination is associated with one session only rather than with a
user (and all their sessions).

It is then also possible to send a message to a user destination
via "/user/{sessionId}/.." rather than "/user/{user}/...".

That means @SendToUser works relying on the session id of the input
message, effectively sending a reply to destination private to the
session.

A key use case for this is handling an exception with an
@MessageExceptionHandler method and sending a reply with @SendToUser.

Configurable back off for listener recovery

Prior to this commit, DefaultMessageListenerContainer was recovering
on failure using a fixed time interval, potentially in an infinite way.

This commit adds an extra "backoff" property to the container that
permits to fine tune the recovery interval using a BackOff instance.

FixedBackOff provides a fixed interval between two attempts and a
maximum number of retries. ExponentialBackOff increases an initial
interval until a maximum interval has been reached. A BackOff instance
can return a special "STOP" time value that indicates that no further
attemps should be made. DefaultMessageListenerContainer uses this
value to stop the container.

protected method "sleepInbetweenRecoveryAttempts" has been renamed
to "applyBackOff" and now returns a boolean that indicate if the
back off has been applied and a new attempt should now be made.

Add back-off attribute to JMS namespace

 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.

 Issue: SPR-11746
Add BackOffExecution to isolate state

 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.
