This commit changes all methods that return `Supplier<Stream<T>` to
return `List<T>` instead. This includes the HandlerStrategies, but also
BodyInserter.Context, BodyExtractor.Context, and ServerResponse.Context.
The reason for this change is that most of the strategies have some sort
of order, where more specific message readers - for instance - come
before generic ones. Such an ordering can only be enforced through a
List.

This commit removes the RouterFunctions.toHandlerMapping method, in
favor of native support for RouterFunctions in @EnableWebFlux
configuration classes.
In order to accomplish this, the HandlerStrategies components has been
repurposed to only be used for the "bare-bones" HttpHandler, while the
(newly introduced) RouterFunctionMapping uses the strategies as exposed
through WebFluxConfigurationSupport.
Furthermore, this commit also introduces support for testing
RouterFunctions without resorting to an application context.
Issue: SPR-15536
This commit adds support for configuring `WebFilter` and
`WebExceptionHandler` instances in HandlerStrategies. It also drops the
"native" support for `ResponseStatusException`s, in favor of the
`ResponseStatusExceptionHandler`, which is registered by default.

The ResourceHandlerFunction now returns an `EntityResponse<Resource>`
(instead of a `ServerResponse`), so that filters can inspect/change the
returned Resource.
Starting with removing a package cycle on the use of
ResponseStatusException in the codec package, this commit generally
refines codec exception handling.
The new [Encoding|Decoding]Exception mirror the existing
HttpMessageNot[Readable|Writable]Exception and are used similarly
especially to differentiate betwen 400 and 500 errors when parsing
server request body content.
The commit also aligns some of the exception handling of JSON and XML
on the WebFlux side with that on the Spring MVC side.

This commit turns the Synchronoss NIO Multipart HttpMessageReader into
a reader of Flux<Part> and creates a separate reader that aggregates
the parts into a MultiValueMap<String, Part>.

With this commit, ServerCodecConfigurer is now exposed as a bean in
order to be provided to DefaultServerWebExchange via
WebHttpHandlerBuilder and HttpWebHandlerAdapter. This allows
DefaultServerWebExchange to get configured codecs for reading form or
multipart requests.

This commit changes the handling of 4xx/5xx status codes in the
WebClient to the following simple rule: if there is no way for the user
to get the response status code, then a WebClientException is returned.
If there is a way to get to the status code, then we do not return an
exception.
Issue: SPR-15486
This commit renames `WebClient.ResponseSpec.bodyToEntity` to `toEntity`
and similarly renames `WebClient.ResponseSpec.bodyToEntityList` to
`toEntityList`. In both cases, the `body` prefix was dropped because the
return value contains more than the body.
Issue: SPR-15486
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.
Issue: SPR-15461
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.
