Main differences with the Spring MVC original implementation:
- Default redirect HTTP code is 303 See Other since we can assume
all HTTP clients support HTTP 1.1 in 2016
- No more http10Compatible property, use statusCode instead
- By default the redirect is relative to the context path
- A builder allow to set various properties if needed
- In UrlBasedViewResolver, a Function<String, RedirectView>
redirectViewProvider property allows to customize RedirectView
instances in a flexible way

Simplify getAdapterFrom/To into a single getAdapter method that looks
for an exact match by type first and then isAssignableFrom.
Also expose shortcut methods in ReactiveAdapter to minimize the need
for access to the ReactiveTypeDescriptor.
Issue: SPR-14902
The ReactiveAdapterRegistry now detects the presence of Reactor. In
practice Reactor is required for the Spring Framework reactive support
and it is expected to be present.
The registry however is now capable of being neutral if Reactor is not
present on the classpath for example where other Spring projects may
not have the same assumptions about Reactor's presence.

Collapse ReactiveAdapter hierarchy into a single class that simply
delegates to functions for converting to/from a Publisher.
A private ReactorAdapter extension automaticlaly wraps adapted, "raw"
Publisher's as Flux or Mono depending on the semantics of the target
reactive type.

This commit polishes previous one by also accepting
generic types explicitly declared with a class that
extends DataBuffer allowing to write Flux<DefaultDataBuffer>
for example.
Issue: SPR-14952
This modifies the signature of
ReactiveHttpOutputMessage#writeAndFlush(...) in order to
be able to use Flux<Flux<DataBuffer>> objects as arguments of
this method.

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.
Issue: SPR-14165
Where `isOptional` is used, also check for `isNullable` i.e.
values are not considered required if they are Kotlin nullables:
- spring-messaging: named value method arguments
- spring-web: named value method arguments
- spring-webmvc: request parts
This means that Kotlin client code no longer has to explicity specify
"required=false" for Kotlin nullables -- this information is inferred
automatically by the framework.

In case the filter is also registered to the ERROR dispatcher, the
following happens:
* the filter is executed once for the regular execution
* the filter should be executed a second time when dispatched to error
Since the filter is a `OncePerRequestFilter`, the filter is only
executed once and won't be executed when handling the error.
This can lead to situations like spring-projects/spring-boot#7348
This commit makes this filter a simple `GenericFilterBean`.

When processing a "close" notification from the server make an effort
to cancel any outstanding heartbeat but avoid going as far as acquiring
the responseLock since the server itself may already hold a lock of its
own leading to a potential deadlock.
The heartbeat task is now also further protected with an isClosed()
check in case the heartbeat does not get cancelled in a concurrent
scenario.
