This commit introduces a new AbstractReactiveWebInitializer in
spring-web that relies on WebHttpHandlerBuilder to detect request
processing infrastructure beans from an ApplicationContext.
This eliminates the need to create a DispatcherHandler, since it is
expected to be a Spring bean, and as a result the initializers in
spring-webflux have been deprecated.

The RFCs around basic authentication don't explicitly disallow empty
usernames. On the other hand usernames containing colons are, as colons
are used to separate the username from the password.
FromHttpMessageWriter and MultipartHttpMessageWriter both support
MultiValueMap except the former supports String values only. This
presents an issue since either full generic type information must be
provided, which is cumbersome on the client side, or if left out there
is no good way to order the writers to make a proper decision.
This commit:
- refines the canWrite behavior of to not a
accept MultiValueMap without proper generic information unless the
MediaType is explicitly set providing a strong hint.
- modifies MultipartHttpMessageWriter to be configured with a
FormHttpMessageWriter so it can write both plan and multipart data with
the ability to properly differentiate based on actual map values.

This commit changes the way Undertow's PooledByteBuffers are dealt with.
Previously, these buffers where closed as soon as all data was read. As
of this commit, the UndertowServerHttpRequest returns PooledDataBuffers
from getBody(), so that the buffers are released when release() is
called.
This commit introduces various improvements in DataBuffer:
- DataBuffer now exposes its read and write position, as well as its
capacity and writable byte count.
- Added DataBuffer.asByteBuffer(int, int)
- DataBufferUtils.read now reads directly into a DataBuffer, rather than
copying a ByteBuffer into a DataBuffer
- TomcatHttpHandler now reads directly into a DataBuffer

Includes redeclaration of CodecConfigurer.DefaultCodecs without concrete Jackson decoder/encoder references in order to avoid hard Jackson dependency.
Issue: SPR-16064
Concrete server and client, reactive request and response
implementations should not have to be accessed outside their package.
They could be seen as private to their HttpHandler adapters and
ClientHttpConnector's respectively.
The one exception, WebSocket upgrades in spring-webflux, is an internal
framework use case, accommodated via downcast + accessors in the
abstract base classes.
Prior to this commit, asking for a `Void` type using any of the
`ClientResponse#bodyTo*` methods would immediately return an empty
`Publisher` without consuming the response body.
Not doing so can lead to HTTP connection pool inconsistencies and/or
memory leaks, since:
* a connection that still has a response body being written to it cannot
be properly recycled in the connection pool
* incoming `DataBuffer` might not be released
This commit detects when `Void` types are asked as body types and in
those cases does the following:
1. Subscribe to the response body `Publisher` to allow the connection to
be returned to the connection pool
2. `cancel()` the body `Publisher` if the response body is not empty; in
that case, we choose to close the connection vs. consume the whole
response body
Those changes imply that `ClientHttpResponse` and other related
contracts don't need a `close()` method anymore.

Includes unified detection of Kotlin's optional parameters in MethodParameter.isOptional(), reduces BeanUtils.findPrimaryConstructor to Kotlin semantics (for reuse in AutowiredAnnotationBeanPostProcessor), and finally introduces a common KotlinDetector delegate with an isKotlinType(Class) check.

Issue: SPR-16020
Prior to this issue, SPR-15920 added this new `close()` method which was
supposed to be called to clean resources after response processing.
This commit changes the meaning of that method: calling `close()` will
close the underlying HTTP connection. This has to be called if the
response body is not consumed by the application, since at that point
the underlying connection might be in an inconsistent state if shared in
a connection pool.

Now that WebSessionStore is in charge of expiration checks on retrieve
it makes sense to also update the lastAccessTime on retrieve at the
same time, saving the need to call it after a retrieve.
Issue: SPR-15963
It is no longer adequate to list supported arguments and return values
-- between Web MVC and WebFlux, directly on the annotation.
Instead we have tables in the respective chapters in the reference with
cross references to each other.
Issue: SPR-15149
This commit makes Reactor Netty `WebClient` instances
support zero-copy requests by implementing `ZeroCopyHttpOutputMessage`.
The implementation leverages the optimized `sendFile` mechanism if
available.
