This commit adds support for reactive library types to be returned
directly from controller methods adapting them either to a
ResponseBodyEmitter (streaming) or DeferredResult (non-streaming).
The reactive libraries supported are the ones that can adapted to a
Reactive Streams Publisher through the ReactiveAdapterRegistry.

Revise Javadoc on AsyncHandlerMethodReturnValueHandler to clarify its
main purpose is to prioritze custom async return value handlers ahead
of built-in ones. Also replace the interface from built-in handlers
which are prioritized already.
Remove DeferredResultAdapter and ResponseBodyEmitterAdapter --
introduced in 4.3 for custom async return value handling, since for
5.0 we will add built-in support for reactive types and the value of
these contracts becomes very marginal.

This change allows the functional WebFlux API to support natively
reactive types and also makes it possible for View implementations to
disable async attributes resolution if they want for example take
advantage of stream rendering.
It also makes AbstractView#getModelAttributes() asynchronous.

Replace the overloaded "retrieve" methods with a single retrieve() +
ResponseSpec exposing shortcut methods (bodyToMono, bodyToFlux)
mirroring the ClientResponse shortcuts it delegates to.
Unlike exchange() however with retrieve() there is no access to other
parts of ClientResponse so ResponseSpec exposes additional shortcuts
for obtain ResponseEntity<T> or ResponseEntity<List<T>>.

This commit makes a change to WebClient in oder to facilitate getting
the response body as a `Mono<Object>` or `Flux<Object>` without having
to deal with `ClientResponse`.
Specifically, this commit:
- Adds `RequestHeaderSpec.retrieve` methods, next to `exchange`, that
return the response body (and not a `ClientResponse`). Two convenience
methods return the response body as `Mono` or `Flux`.
- Adds ClientResponse.toRequestEntity to convert the ClientResponse
into a RequestEntity.

The ServerCodecConfigurer is now passed all the way into the
RequestMappingHandlerAdapter which automatically enables the same
defaults even without the Java config and provides extra flexibility
in passing message codec configuration for the future.
Restore the correct client-side default for whether StringDecoder
should split on new lines. It is true forthe server and false for the
client by default.
The regression was introduced in the recent refactoring:

This commit makes changes to WebClient and WebTestClient in oder to
limit setting the body according to HTTP method and also to facilitate
providing the request body as Object.
Specifically, this commit:
- Moves methods that operate on the request body to a RequestBodySpec
in both WebClient and WebTestClient, and rename them to `body`.
These methods now just *set* the body, without performing
an exchange (which now requires an explicit exchange call).
- Parameterizes UriSpec in both WebClient and WebTestClient, so that
it returns either a RequestHeadersSpec or a RequestBodySpec.

This commit deprecates `AsyncRestTemplate` and related types
(`AsyncClientHttpRequestFactory` etc.) in favor of the Spring 5.0
`WebClient`.

This commit removes docbook from the documentation toolchain and
instead makes use of asciidoctor to render the reference documentation
in HTML and PDF formats.
The main Gradle build has been refactored with the documentation tasks
and sniffer tasks extracted to their own gradle file in the "gradle"
folder.
A new asciidoctor Spring theme is also used to render the HTML5 backend.

Extract controller method caches including associated code and
discovery of @ControllerAdvice components into a separate, package
private helper class (ControllerMethodResolver).
