This commit makes Spring @Nullable annotation leveraging
JSR 305 @TypeQualifierNickname + @Nonnull(when= When.MAYBE)
instead of directly using @javax.annotation.Nullable which
seems not designed to be used as a meta-annotation.
It also removes @TypeQualifierDefault since the purpose of
this annotation when applied at method level is to only
change return value nullability, not parameters one.

This commit replaces the UnaryOperatory<ServerWebExchange> inputs with
Function<ServerWebExchange, ServerWebExchange> instead. Unfortunately
the composability methods inherited from Function don't work in terms
of generics for composing multiple UnaryOperator's.

Provide a mechanism to override the configured send and receive
timeouts in the GenericMessagingTemplate.
- overload `doReceive()` to take a receive timeout argument
- for `sendAndReceive()` methods examine message headers for these
timeout values
- remove headers to avoid propagation
- avoid the unconditional rebuild of the reply message if the
original headers weren't present
- also remove headers from simple `send()` operations
- change javadocs for the setters to indicate they are now defaults
- add properties to allow the user to override the header names used
- change `TemporaryReplyChannel` to use `send` arg and change to static
- add package-protected ctor to avoid the compiler creating a
synthetic constructor for access

This commit introduces ExtractingResponseErrorHandler: an alternative
ResponseErrorHandler that uses `HttpMessageConverter`s to convert HTTP
error responses to `RestClientException`.
Issue: SPR-15544
Simplify the internals of the DefaultCodecs implementation favoring
explicit fields per override vs a generic list of readers and writers
for overrides.
This commit introduces 2 new @Nullable and @NonNullApi
annotations that leverage JSR 305 (dormant but available via
Findbugs jsr305 dependency and already used by libraries
like OkHttp) meta-annotations to specify explicitly
null-safety of Spring Framework parameters and return values.
In order to avoid adding too much annotations, the
default is set at package level with @NonNullApi and
@Nullable annotations are added when needed at parameter or
return value level. These annotations are intended to be used
on Spring Framework itself but also by other Spring projects.
@Nullable annotations have been introduced based on Javadoc
and search of patterns like "return null;". It is expected that
nullability of Spring Framework API will be polished with
complementary commits.
In practice, this will make the whole Spring Framework API
null-safe for Kotlin projects (when KT-10942 will be fixed)
since Kotlin will be able to leverage these annotations to
know if a parameter or a return value is nullable or not. But
this is also useful for Java developers as well since IntelliJ
IDEA, for example, also understands these annotations to
generate warnings when unsafe nullable usages are detected.

As a follow-up to the recent commit 246e72 some slight modifications
to MockServerExchangeMutator (renamed to ExchnageMutatorWebFilter).
Aside from the name change, the main difference is that "per request"
exchange processors are now simply applied via WebTestClient#filter(..).

This commit also changes "hibval5Version" to the more general "hibvalVersion" build variable, and includes dependency updates to Caffeine 2.5.1 and JRuby 9.1.9.
Issue: SPR-13482
This commit replaces the option to bind the WebTestClient to an
HttpHandler to bind to a WebHandler instead.
This allows testing below the WebFlux level such as WebFilter,
WebHandler, or WebSession scenarios, but still a level above
HttpHandler so that WebTestClient is in charge of creating the
ServerWebExchange and expose consistently the
WebTestClient#MockServerSpec setup across all "mock" server bindToXxx
options.
Issue: SPR-15570
This commit factors ServerWebExchange mutator support out of
WebTestClient in favor of an independent public class called
MockServerExchangeMutator which implements WebFilter and can be
applied to the WebTestClient as any other WebFilter.
The MockServerExchangeMutator also exposes a method to apply
a client-side filter for "per request" mutators. See the Javadoc
of the MockServerExchangeMutator.

This commit introduces a new method in HttpRequest:
`String getMethodValue`, which returns the HTTP method as a String.
Furthermore, HttpRequest.getMethod() has been given a default
implementation using this String value in combination with
`HttpMethod.resolve`.
Issue: SPR-15545
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.
Issue: SPR-15578
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
Prior to this commit, resolving resources from webjars using the
`WebJarAssetLocator.getFullPath` could lead to multiple candidates,
since this method is trying to find *any* resource matching that path
under the given webjar location.
This commit replaces that call with
`WebJarAssetLocator.getFullPathExact`, which avoids those multiple
matches and only resolves resources if the given path is exact.
