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.

Collapse the base interface VersionPathStrategy into its extension
VersionStrategy and then turn the prefix nad fliename based
implementations into abstract base classes (vs delegate strategies).
It is simpler to have one VersionStrategy hierarchy vs that plus a
separate VersionPathStrategy as a delegate. In practice each
VersionStrategy is suited to be prefix or filename based. Also none
of our code cares about the distinction between those two interfaces.
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`.

Currently ResourceEncoder and ResourceRegionEncoder use DataBufferUtils
to read resource with an AsynchronousFileChannel if it is a file or
otherwise fallback on getting the channel from the resource.
The same is now required in other places where a Resource needs to be
read and is also generally useful.

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 changes the write methods to return `Flux<DataBuffer>`
instead of `Mono<Void>`, giving access to the original buffers,
so that they can decided whether the buffers need to be closed or not.
Issue: SPR-15726
This commit adds an overloaded write method to `DataBufferUtils`. There
are three parameter variants: `OutputStream`, `WritableByteChannel`, and
`AsynchronousFileChannel`.

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
Avoid re-using the WriteBarrier as the Subscription to both the
completionSubscriber and the writeSubscriber.
Instead DownstreamBridge is now called WriteCompletionBarrier and is
both a Subscriber and Subscription, i.e. handles all signals to and
from the completion Subscriber.
This frees the request method implementation in WriteBarrier to assume
it can only be called by the writeSubscriber and hence it's safe to
pass on request signals to the write source outside the synchronized
block.
This commit introduces a boolean `readOnly` flag in `HttpHeaders`,
which is used to check if creating a new `HttpHeaders` instance is
necessary in `readOnlyHttpHeaders`.
