Forwarded headers are now processed before ServerWebExchange is created
through ForwardedHeaderTransformer which has the same logic as the
ForwardedHeaderFilter but works on the request only.
ForwardedHeaderFilter is deprecated as of 5.1 but if registered it is
removed from the list of filters and ForwardedHeaderTransformer is used
instead.

Empty Maps are preferably initialized without capacity (not initializing them at all or lazily initializing with default capacity when needed).

This commit introduces Protobuf support in WebFlux via dedicated
codecs.
Flux<Message> are serialized/deserialized using delimited Protobuf
messages with the size of each message specified before the message
itself. In that case, a "delimited=true" parameter is added to the
content type.
Mono<Message> are expected to use regular Protobuf message
format (without the size prepended before the message).
Related HttpMessageReader/Writer are automatically registered when the
"com.google.protobuf:protobuf-java" library is detected in the classpath,
and can be customized easily if needed via CodecConfigurer, for example
to specify protocol extensions via the ExtensionRegistry based
constructors.
Both "application/x-protobuf" and "application/octet-stream" mime types
are supported.
Issue: SPR-15776
In order to be consistent with SPR-15776, and since it does not
provide clear added value, this commit deprecates
ExtensionRegistryInitializer and uses ExtensionRegistry
parameter instead in ProtobufHttpMessageConverter and
ProtobufJsonFormatHttpMessageConverter constructors.
Issue: SPR-17081
This commit ignores errors like TransformerFactoryConfigurationError
that can be thrown when instantiating SourceHttpMessageConverter on
platforms where no TransformerFactory implementation is available,
like when compiling/running as GraalVM native images.
Issue: SPR-17007
Since SPR-15205, the `FormHttpMessageConverter` is adding a `charset`
directive to the `Content-Type` request header in order to help servers
understand which charset is being used to encode headers of each part.
As reported in SPR-17030 and others, some servers are not parsing
properly such header values and assume that `boundary` is the last
directive in the `Content-Type` header.
This commit reorders the charset information right before the boundary
declaration to get around those issues.

See Javadoc on UriComponentsBuilder#uriVariables for details.
This helps to prepare for SPR-17027 where the MvcUriComponentsBuilder
already does a partial expand but was forced to build UriComonents
and then create a new UriComponentsBuilder from it to continue. This
change makes it possible to stay with the same builder instance.
Issue: SPR-17027
After the latest changes, two small fixes in the clone method to copy
the encode flag, and in the encodeUriTemplate method to account for
possible null query params.
Improvements in the URI encoding section.

The HandlerMethodParameter arrangement uses an approach similar to ModelAttributeMethodProcessor's FieldAwareConstructorParameter, merging the local parameter annotations with interface-declared annotations.
