This commit renames the `body(Object)` on ServerResponse to
`syncBody(Object)`. The reason for this is that the original method
name clashed with the `body(Publisher)` method in the Kotlin extension.
The new name nicely reflects the synchronous nature of the method,
making it less appealing than the `Publisher`-based `body` method.
Issue: SPR-15467
This method introduces a new body(Object) to ServerResponse, a shortcut
to body(BodyInserters.fromObject(Object)).
Note that in the implementation of the method, an `instanceof` check is
performed to make sure that the passed argument is not a `Publisher`,
as users should call `body(Publisher, Class)` for sending a reactive
type.
This Publisher-check is also done in the `WebClient`, for the same
reasons.

Without this change it was necessary to call getPathRemaining and
then chop up the path and make a call to matchAndExtract to get the
bound variables for the path part that matched. With this change
this is all done in the call to getPathRemaining which returns
an object holding the remaining path and the bound variables.

This commit changes the `HandlerStrategies` and `ExchangeStrategies`
builders to use the `CodecConfigurer` for configuring Decoder|Encoder
and HttpMessage[Reader|Writer]. Other classes that use `CodecConfigurer`
have also been changed to reflect the refactoring to interfaces.
This commit also removes the ExchangeStrategies methods that take an
application context, as it was too naive approach to simply look up
every message reader and writer in the context.
Issue: SPR-15415, SPR-15435
This commit changes the `HandlerStrategies` builder to use
`ServerCodecConfigurer` for configuring Decoder|Encoder and
HttpMessage[Reader|Writer]. Note that the configurer is not exposed
directly, but wrapped so that `HandlerStrategies` can keep on returning
`this` for a proper builder pattern.
This commit also removes the HandlerStrategies methods that take an
application context, as it was too naive approach to simply look up
every message reader and writer in the context.

- Renamed `defaultCodec` to `defaultCodecs`, and `customCodec` to
`customCodecs`
- Added `@Override` annotations where necessary
- Fixed non-parameterized usage for parameterized types.
This commit makes CodecException handling consistent between functional
and annotation-based APIs. It now returns by default 4xx status code
for decoding error and 5xx for encoding error + print the error reason
in logs without the full stack trace in both variants.

The java.util.Optional wrapper should not affect the support for
"request param" arguments with or without the annotation as it
works on the Spring MVC side.
This commit uses the newly introduced
`PathPattern.getPathRemaining(String)` in the functional web framework.
With this change, all path predicates can be used for nested router
functions, so the `pathPrefix` predicate is no longer required and has
been removed.
Issue: SPR-15336
This commit introduces support for the server-side methods on
HttpMessageReader and HttpMessageWriter. It does so by introducing an
Optional ServerHttpRequest in BodyInserter.Context, and an Optional
ServerHttpResponse in BodyExtractor.Context. On the client-side, these
optionals return Optional.empty(); on the server-side, they return the
respective server-side messages.

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>>.
Issue: SPR-15294
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.
Issue: SPR-15294
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.
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.

Extract controller method caches including associated code and
discovery of @ControllerAdvice components into a separate, package
private helper class (ControllerMethodResolver).
This commit folds ServerHttpMessage[Reader|Writer] into its parent
HttpMessage[Reader|Writer] with the server methods pre-implemented
by default to be simple pass-through delegates.
