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.
Issue: SPR-11755
DestinationCache is now used for both plain and pattern
destinations. It stores internally the subscriptions map for each
cached destination. Subscriptions are initially created when there
is no cache for the requested destination, and are updated when
subscriptions change.

The original fix for SPR-11423:
32e5f57e64
was insufficient when using an external broker since the original
destination header has to be in the "native headers" map (i.e. with
STOMP headers) in order to be included in messages broadcast by
the broker.
This change adds support for Reactor 1.1 in spring-messaging in
addition to Reactor 1.0.1 -- whichever is present on the classpath is
used.
Note also the module name change:
reactor-tcp:1.0.1 -> reactor-net:1.1.0

Prior to this commit, @SubscribeMapping mapped methods (backed with
@SendTo* annotations, or not) would send MESSAGEs with the wrong
destination. Instead of using the original SUBSCRIBE destination, it
would use the lookup path computed from the configured prefixes in the
application.
This commit fixes this issue - now @SubscribeMapping MESSAGEs use the
original SUBSCRIBE destination.

This commit validates that the payload type of the message is
assignable to the one declared in the method signature. If that
is not the case, a meaningful exception message is thrown with
the types mismatch.
Prior to this commit, only the Message interface could be defined
in the method signature: it is now possible to define a sub-class
of Message if necessary which will match as long as the Message
parameter is assignable to that type.

BufferingStompDecoder message buffer size limit can now be configured
with JavaConfig MessageBrokerRegistry.setMessageBufferSizeLimit() or
with XML <websocket:message-brocker message-buffer-size="">.
Issue: SPR-11527
Before this change the StompDecoder decoded and returned only the first
Message in the ByteBuffer passed to it. So to obtain all messages from
the buffer, one had to loop passing the same buffer in until no more
complete STOMP frames could be decoded.
This chage modifies StompDecoder to return List<Message> after
exhaustively decoding all available STOMP frames from the input buffer.
Also an overloaded decode method allows passing in Map that will be
populated with any headers successfully parsed, which is useful for
"peeking" at the "content-length" header.
This change also adds a BufferingStompDecoder sub-class which buffers
any content left in the input buffer after parsing one or more STOMP
frames. This sub-class can also deal with fragmented messages,
re-assembling them and parsing as a whole message.
Issue: SPR-11527
If a payload is present but conversion returns null (meaning no
converter knows how to convert), raise a MessageConversionException
that provides information about the type we were trying to convert
to and the message itself whose headers (namely content-type) contain
crucial information required to debug the problem.
