This commit fixes the write checks for
`ResourceRegionHttpMessageConverter`, which was previously not checking
properly the parameterized type (e.g. in case of a `List<Something>`).

This commit restricts the allowed HTTP methods on HiddenHttpMethodFilter
(Reactive variant) to the following: PUT, DELETE, PATCH.
This filter is meant to be used to simulate those methods from HTML
forms sent by browsers, so no other methods are allowed.

With this commit, WebFlux server uses warning instead of error log level
for request handling, and also just print the message instead of the
stacktrace which is mostly meaningless in reactive world.
Complementary to this change, Reactor Netty removed additional logging
as part of https://github.com/reactor/reactor-netty/issues/339.
Issue: SPR-16688
ServerSentEventHttpMessageReader had logic to split on new lines
and buffer until an empty new line (start of a new event). To account
for random data chunking, it later re-assembled the lines for each
event and split again on new lines. However bufferUntil was still
unreliable a chunk may contain nothing but a newline, which doesn't
necessarily mean an empty newline in the overall SSE stream.
This commit simplifies the above by delegating the splitting of the
stream along newlines to StringDecoder.

Using the simple example shown in the ticket but switching from
Mono<String> to Flux<String> (and 5,000,000 onNext calls) shows that
constant pausing causes significant overhead and is not worth the
trouble vs ignoring the onWritePossible in REQUESTED state.
Issue: SPR-16702
Undertow does not provide a way to check if we can write so with the
current implementation of isWritePossible, deep recursion can occur
when writing slows down. We now use a flag to keep track of write
ChannelListener callbacks.
This commit also addresses a related issue in
AbstractListenerWriteProcessor that went undected since #3c2d186
where after a large (single) buffer that is not written fully, the
completion signal is processed before the all data is written.
Issue: SPR-16702
This breaks the package dependency cycle between web.server/web.method and makes ServerErrorException more generally applicable. Includes deprecation of the plain reason constructor variant, in favor of providing a Method or MethodParameter context (which MatrixVariableMethodArgumentResolver does now).
Consistently return "*/*" if no media types were requested rather than
an empty list. Existing code has to check for both in any case to see
if nothing was requested.
