This commit adds support for single-value reactive types in
@MessageMapping by converting them using ReactiveAdapterRegistry
and MonoToListenableFutureAdapter.
MonoToListenableFutureAdapter previously package private and used only
in org.springframework.messaging.tcp.reactor has been moved to
org.springframework.messaging.support and made public in order to be
used by ReactiveReturnValueHandler as well.

As of 4.3.13 MappingJackson2MessageConverter uses the MethodParameter
hint to obtain generic type information but it needs to be careful, and
nest one level, if the target parameter type has a Message wrapper.

After this commit DefaultUserDestinationResolves no longer looks at
whether AntPathMatcher is configured with "." as separator and rather
expects to be explicitly told whether to keep the leading slash in
translated destinations which actually depends on what the message
broker supports (e.g. RabbitMQ "/", Artemis ".") or how it is
configured (simple broker could be either way).
There is also a minor improvement in SimpMessagingTemplate to ensure
user destinations are correctly formed based on what the
DefaultUserDestinationResolver expects. When using "." as separtor it
allows sending messages to "queue.q1" rather than "/queue.q1".

SimpMessageTypeMessageCondition was lenient in matching the message
type, essentially matching on any non-null message type with an exact
match given a preference only in comparing mulitple matches.
This commit modifies matching logic to look for an exact match.

Also, ChannelRegistration.setInterceptors is deprecated now: in favor of a fluently named interceptors(...) method which is documented to add the given interceptors to the channel's current list.

Includes general streamlining of dependency declarations with reduced version variables, direct use of EclipseLink 2.7 and its implicit JPA 2.2 dependency in spring-orm, mixed use of Hibernate 5.2.10 and 5.1.10 for integration tests, as well as an upgrade to Jetty 9.4.7 RC0 and a downgrade to Groovy 2.4.12 (since Groovy 2.5 won't be final in time for Spring Framework 5.0).

Beyond just formally declaring the current behavior, this revision actually enforces non-null behavior in selected signatures now, not tolerating null values anymore when not explicitly documented. It also changes some utility methods with historic null-in/null-out tolerance towards enforced non-null return values, making them a proper citizen in non-null assignments.
Some issues are left as to-do: in particular a thorough revision of spring-test, and a few tests with unclear failures (ignored as "TODO: NULLABLE") to be sorted out in a follow-up commit.

Provide a mechanism to override the configured send and receive
timeouts in the GenericMessagingTemplate.
- overload `doReceive()` to take a receive timeout argument
- for `sendAndReceive()` methods examine message headers for these
timeout values
- remove headers to avoid propagation
- avoid the unconditional rebuild of the reply message if the
original headers weren't present
- also remove headers from simple `send()` operations
- change javadocs for the setters to indicate they are now defaults
- add properties to allow the user to override the header names used
- change `TemporaryReplyChannel` to use `send` arg and change to static
- add package-protected ctor to avoid the compiler creating a
synthetic constructor for access

This commit polishes Kotlin nullable support by reusing
MethodParameter#isOptional() instead of adding a new
MethodParameter#isNullable() method, adds
Kotlin tests and introduces Spring Web Reactive
support.
