Before this commit, there was no way to signal the HTTP client that we
were done consuming the response. Without that, the underlying client
library cannot know when it is safe to release the associated resources
(e.g. the HTTP connection).
This commit adds new `close()` methods on both `ClientHttpResponse`
and `ClientResponse`. This methods is non-blocking and its behavior
depends on the library, its configuration, HTTP version, etc.
At the `WebClient` level, `close()` is called automatically if we
consume the response body through the `ResponseSpec` or the
`ClientResponse` itself.
Note that it is *required* to call `close()` manually otherwise; not
doing so might create resource leaks or connection issues.

The PathPattern compareTo method is now consistent with equals when
two patterns are of the same specificity but otherwise different.
Separately PathPattern now exposes a Comparator by specificity that
offers the current functionality of compareTo. This can be used for
actual sorting where we only care about specificity.
Rename getPathRemaining to matchStartOfPath since the method does
match and to be more clear about what the method and the return value
intuitively follows.
Remove matchStart which matches the start of the pattern (rather than
the start of the path). It is a use case that does not come up in
request mapping.
This commit changes the WebClient so that it now throws a
`WebClientResponseException` for `ResponseSpec.bodyTo`. This newly
introduces exception contains the status code, headers, and body of the
response message.
As a consequence of the above, we had to change `onStatus` so that the
`exceptionFunction` now returns a `Mono<Throwable>` rather than a
`Throwable`, which it was before. The Mono allows for asynchronous
operations, such as reading the contents of the body.

Removed superfluous `fromServerSentEvent` variants from `BodyInserters`,
as their functionality can also be obtained by passing a stream of
strings or POJOs (to be encoded as JSON) to
`fromPublisher(Publisher, Class)}`, and specifying a `text/event-stream`
Content-Type.

This commit also removes WebFlux non-extension functions in favor of
regular Kotlin extensions leveraging ParameterizedTypeReference parameter.

This commit changes the usage of two separate attributes (username and
password) into one: a single `Credentials` object.
Additionally, the attributes key under which the credentials are stored
is changed to be specific to Basic Authentication, in order to allow for
other sorts of authentication later.

This commit changes adds overloaded `ParameterizedTypeReference `
variants to body-related methods in `ServerRequest` and
`ServerResponse`.
It also adds a single PTR variant to ClientRequest, which was missing
before.
Issue: SPR-15817
This commit changes all consumers of CodecConfigurer to consume a `List`
of HttpMessageReaders or HttpMessageWriters instead of consuming the
Server- or ClientCodecConfigurer directly.

Since there is no reason for an exchange to ever complete without a
ClientResponse I've added a switchIfEmpty check at the WebClient level.
Also, temporarily a second check closer to the problem in the
ReactorClientHttpConnector suggesting a workaround and providing a
reference to the Reactor Netty issue #138.
Issue: SPR-15784
Since `PathPattern.combine` now returns another `PathPattern` instance
(it was previously returning a String instance), we can now safely
remove the parser instance included in `PatternsRequestCondition`.
Issue: SPR-15663
Use copy constructor to refresh a session with lastAccessTime and a
save function referencing the current exchange. As a result both fields
are now final and ConfigurableWebSession is no longer needed.
This commit introduces overloaded variants of `bodytoMono`,
`bodyToFlux`, `toEntity`, and `toEntityList` that take a
`ParameterizedTypeReference`. It also adds similar methods to
`WebClient.ResponseSpec`.

This binary format more efficient than JSON should be useful for server
to server communication, for example in micro-services use cases.
Issue: SPR-15424
This commit introduces an apply method to `WebClient.Builder`, allowing
users to make multiple changes to the builder in one consumer.
Issue: SPR-15743
The failures look like older failures possibly exposed by recent
changes in Reactor.
The one in ViewResolutionResultHandler is very old test error.
The one in Jackson2JsonDecoderTests is more recent but went unreported.
This commit moves `toEntity(Class<T>)` and `toEntityList(Class<T>)`
from WebClient.ResponseSpec to ClientResponse. The main reason for doing
so is that the newly introduced `onStatus` method (see
2f9bd6e075) does not apply to these two
methods, and the result would be confusing. Also, `ClientResponse` and
`ResponseEntity` represent the same data: status code, headers, and a
body.
Issue: SPR-15724
This commit introduces a way to customize the WebClientExceptions, as
thrown by WebClient.ResponseSpec.bodyTo[Mono|Flux]. The first
customization will override the defaults, additional customizations are
simply tried in order.
Issue: SPR-15724
This commit changes `ServerRequest.attribute(String)`` to return
`Optional<Object>` instead of `Optional<T>`, where `T` was infered
from a type parameter.
Explicitly pass the client-side JSR-356 WebSocketContainer to the
TomcatWebSocketClient to prevent the ContainerProvider from finding
the one from undertow-websockets-jsr through the ServiceLoader API.
This commit disables the "failOnServerError" feature on the
`HttpClientRequest`, as wrapped by ReactorClientHttpRequest. 5xx errors
are supposed to be dealt with in the WebClient, not in the lower-level
components.
