The WebSocketHandler adapters for all runtimes now extend
WebSocketHandlerAdapterSupport, which now also exposes
a shared DataBufferFactory property initialized from the response.
Issue: SPR-14527
suspend/resumeReceiving in the AbstractListenerWebSocketSession are
now abstract methods. In Tomcat/Jetty these methods are no-op
implementations that are then coupled with a buffering strategy via
Flux#onBackpressureBuffer. In Undertow they rely on flow control for
receiving WebSocket messages.
Issue: SPR-14527
- Added suspended flag to indicate whether the ReceivePublisher
is able to process the incoming messages.
- Use buffer strategy for the incoming messages.
Issue: SPR-14527
Dropped "Support" from the name since it not only provides support
methods but actually implements WebSocketSession.
Renamed inner classes:
WebSocketMessagePublisher -> WebSocketReceivePublisher
WebSocketMessageProcessor -> WebSocketSendProcessor
Add protected getter for sendProcessor.
Reduce scoping:
WebSocketReceivePublisher -> private
WebSocketSendProcessor -> protected
WebSocketSendProcessor#setReady -> public (class is still protected)
A few more method name alignments and Javadoc updates.
Issue: SPR-14527
AbstractRequestBodyPublisher and AbstractResponseBodyProcessor are now
used for WebSocket messages too and have been renamed more generally to
AbstractListenerReadPublisher and AbstractListenerWriteProcessor.

When getting the lookup path of a resource, both query params and hashes
should be removed from the request path.
This commit fixes the public path resolution for paths like
`/resources/main.svg#icon-hamburgermenu`.

This commit changes RouterFunctions.toHttpHandler to return
HttpWebHandlerAdapter (instead of HttpHandler), so that WebFilters and
WebExceptionHandler can be applied to it.
Issue: SPR-14979
This commit adds the ability to serve Resources (static files) through a
RouterFunction. Two methods have been added to RouterFunctions: one that
exposes a given directory given a path pattern, and a generic method
that requires a lookup function.

In general, web.util is supposed to remain lowest-level, not depending on any other web.* package. Since web.client also has a support package, a corresponding web.server.support package seemed appropriate for a helper class depending on ServerWebExchange in web.server itself.
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
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 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
Multi-value async attributes like Flux and Observable in the model
are treated with Collection semantics and resolved to Mono<List<?>>
prior to rendering.
When resolved through the `GzipResourceResolver`, CSS files can be
resolved as their pre-gzipped variant, if a ".gz" file is present in the
configured resource locations.
Such resources are gzipped and thus should not be transformed by
`CssLinkResourceTransformer`s, since rewriting those would need to
uncompress/transform/recompress. This would lead to poorer performances
than resolving plain resources and delegating compression to the
container.
This commit checks for `GzippedResource` instances in
`CssLinkResourceTransformer` and avoids processing them.
Issue: SPR-14773
If the body class is not resolvable from the return type and there is
a body instance we now fall back on the class of the body instance.
