1. Use special category prefix "spring-web.reactivestreams" for logging
of reactive streams signals in spring-web, since those are quite
verbose would fill the logs at TRACE.
2. Add and use loggers in request and websocket session implementations
separate from reactive streams bridge for regular TRACE logging.
3. Improve log messages and add where missing (e.g. for Reactor)

This commit introduces RouterFunctions.Builder, a new way to build
router functions that does not require static imports, thus being more
discoverable and convenient.

Polish a few issue identified when adding checkstyle to the
build. Although checkstyle is not enforcing rules on tests,
these are a few minor changes that are still worth making.

In SPR-16892, the `EncoderHttpMessageWriter` has been improved to write
`"Content-Length"` HTTP response headers if the response body is of type
`Mono` (i.e. the actual content length is easily accessible without
buffering a possibly large response body). That change was relying on
the fact that the server side is using a `ChannelSendOperator` to delay
the writing of the body until the first signal is received.
This strategy is not effective on the client side, since no such channel
operator is used for `WebClient`. This commit improves
`EncoderHttpMessageWriter` and delays, for `Mono` HTTP message bodies
only, the writing of the body so that we can write the
`"Content-Length"` header information once we've got the body resolved.

The key in CachingResourceResolver now includes the "Accept-Encoding"
request header cleaned to exclude "*", "identity", and parameters, and
also sorted alphabetically.
For encoded resources the response now includes a response header with
"Vary: Accept-Encoding".

The new EncodedResourceResolver is a generalized version of
GzipResourceResolver that can be configured to support different
content codings, by "br" and "gzip".
GzipResourceResolver is now deprecated.

This commit makes it possible to pass attributes from the WebSession of
a handshake request to the WebSocketSession, by configuring a
Predicate<String> on HandshakeWebSocketService.
Issue: SPR-16212
This commit removes all places where forwarded headers are checked
implicitly, on an ad-hoc basis.
ForwardedHeaderFilter is expected to be used instead providing
centralized control over using or discarding such headers.
Issue: SPR-16668
This commit exposes the resource lookup function used by
`RouterFunctions.resources(String, Resource)`, so that it can be
composed upon.
Issue: SPR-16788
This commit introduces support for creating a new `ServerRequest` from
an existing instance. This is especially useful when filtering requests
in a HandlerFilterFunction.
