This is similar to the WriteListener changes on the ServerHttpResponse
where we are more naturally exposed to a delayed write. Nevertheless
we could also have a delayed read and should be consistent. The early
initialization of the RequestBodyPublisher also simplifies the
internal implementation a bit.
Instead of registering an AsyncListener in ServletHttpHandlerAdapter
we now register an AsyncListener in each of the request and response
where the events need to be handled anyway. This allows removing the
package private delegation methods in the request and response.
This commit makes it possible for handler functions to return
asynchronous status codes and headers, by making HandlerFunction.handle
return a Mono<ServerResponse> instead of a ServerResponse. As a
consequence, all other types that deal with HandlerFunctions
(RouterFunction, HandlerFilterFunction, etc.) had to change as well.
However, when combining the above change with method references (a very
typical use case), resulting signatures would have been something like:
```
public Mono<ServerResponse<Mono<Person>>> getPerson(ServerRequest request)
```
which was too ugly to consider, especially the two uses of Mono. It was
considered to merge ServerResponse with the last Mono, essentialy making
ServerResponse always contain a Publisher, but this had unfortunate
consequences in view rendering.
It was therefore decided to drop the parameterization of ServerResponse,
as the only usage of the extra type information was to manipulate the
response objects in a filter. Even before the above change this was
suggested; it just made the change even more necessary.
As a consequence, `BodyInserter` could be turned into a real
`FunctionalInterface`, which resulted in changes in ClientRequest.
We did, however, make HandlerFunction.handle return a `Mono<? extends
ServerResponse>`, adding little complexity, but allowing for
future `ServerResponse` subtypes that do expose type information, if
it's needed. For instance, a RenderingResponse could expose the view
name and model.

Similar pattern as for ServerWebExchange with a default mutate method
on ServerHttpRequest returning a Builder and eventually creating an
immutable wrapper.
HttpHandlerAdapterSupport uses the builder to set the contextPath.
Now that reactor/reactor-netty#12 is fixed, we can restore the
previously ignored integration tests.
New tests are hanging, so this commit is converting the `StepVerifier`
`verify()` calls to using actual timeouts.

AbstractRequestBodyPublisher and AbstractResponseBodyProcessor are now
used for WebSocket messages too and have been renamed more generally to
AbstractListenerReadPublisher and AbstractListenerWriteProcessor.
Issue: SPR-14527
This commit ensures that POST/PUT requests sent by the Netty client have
a Content-Length header set.
Integration tests have been refactored to use mockwebserver instead of
Jetty and have been parameterized to run on all available supported
clients.

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 adds a HTTP PATCH operation to the RestTemplate:
patchForObject. As with most operations, there are three variants:
varargs, Map, and URI based.
Issue: SPR-14857
This commit introduces a new ContentDisposition class designed
to parse and generate Content-Disposition header value as defined
in RFC 2183. It supports the disposition type and the name,
filename (or filename* when encoded according to RFC 5987) and
size parameters.
This new class is usually used thanks to
HttpHeaders#getContentDisposition() and
HttpHeaders#setContentDisposition(ContentDisposition).

- ScriptedSubscriber has been renamed to Verifier
- The Publisher is passed to create() instead of verify()
- No more need to specify the generic type explicitly
- Version is now sync with reactor-core
Issue: SPR-14800
The ServerWebExchange now has a getFormData() method that delegates to
FormHttpMessageReader for the parsing and then caches the result so
it may be used multiples times during request processing.
Issue: SPR-14541
This commit introduces two new `WebClient` methods: `retrieveMono` and
`retrieveFlux`, both of which offer direct access to the response body.
More importantly, these methods publish a WebClientException if the
response status code is in the 4xx or 5xx series.
Issue: SPR-14852
This commit introduces a couple of changes to BodyInserters:
- Refactored writeWithMessageWriters into BiFunction
- BodyInserters.fromResource now uses ResourceMessagewriter from context
- BodyInserters.fromServerSentEvents now uses SseHttpMessageWriter from context
Reactor recently added the `ScriptedSubscriber` in its new
`reactor-addons` module. This `Subscriber` revissits the previous
`TestSubscriber` with many improvements, including:
* scripting each expectation
* builder API that guides you until the final verification step
* virtual time support
This commit refactor all existing tests to use this new
infrastructure and removed the `TestSubscriber` implementation.
