This commits extends nullability declarations to the field level, formalizing the interaction between methods and their underlying fields and therefore avoiding any nullability mismatch.

This commit introduces 2 new public methods in HttpHeaders in order
to leverage Java 8 ZonedDateTime in addition to the existing long
(with GMT time zone implied) variants:
- ZonedDateTime getFirstZonedDateTime(String headerName)
- void setZonedDateTime(String headerName, ZonedDateTime date)
This commit also leverages Java 8 thread-safe DateTimeFormatter for
HttpHeader implementation instead of SimpleDateFormat. As a consequence
of the usage of DateTimeFormatter.RFC_1123_DATE_TIME, HTTP date header
serialization could change slightly for single digit days from for
example "Thu, 01 Jan 1970 00:00:00 GMT" to
"Thu, 1 Jan 1970 00:00:00 GMT".

This commit replaces the WebClient.filter method with
WebClient.Builder.filter. The reason for this change is that filters
added via WebClient.filter would be applied in the opposite order of
their declaration, due to the compositional nature of the method,
combined with the immutable nature of the WebClient.
WebClient.Builder.filter does keep the order of the filters, as
registered.
Furthermore, this commit introduces a WebClient.mutate() method,
returning a WebClient.Builder. This method allow to add/remove filters
and other defaults from a given WebClient.

This commit changes the use of `ResolvableType` to
`ParameterizedTypeReference` in all public-facing WebFlux APIs. This
change removes the necessity for providing the parameterized type
information twice: once for creating the `ResolvableType`, and once for
specifying a `BodyExtractor`.
Issue: SPR-15636
This commit also removes nullability from two common spots: ResolvableType.getType() and TargetSource.getTarget(), both of which are never effectively null with any regular implementation. For such scenarios, a non-null empty type/target is the cleaner contract.
Issue: SPR-15540
Beyond just formally declaring the current behavior, this revision actually enforces non-null behavior in selected signatures now, not tolerating null values anymore when not explicitly documented. It also changes some utility methods with historic null-in/null-out tolerance towards enforced non-null return values, making them a proper citizen in non-null assignments.
Some issues are left as to-do: in particular a thorough revision of spring-test, and a few tests with unclear failures (ignored as "TODO: NULLABLE") to be sorted out in a follow-up commit.
Issue: SPR-15540
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(..).
Issue: SPR-15570
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.
Issue: SPR-15570
According to RFC-6265 that there should be a space between the ; and
the attribute name, i.e. the header should be something like
name=value; Domain=localhost; HttpOnly rather than
name=value;Domain=localhost;HttpOnly
Issue: SPR-15225
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 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.
Issue: SPR-15394
This commit changes the `MockServletContext.getMimeType` method to use
`MediaTypeFactory` instead of JAF. It also adds a `addMimeType(String,
MediaType)` method to customize the mime types returned from said
method.
