Transition from DEMAND->NO_DEMAND:
Two concurrent threads enter DEMAND.request and DEMAND.onDataAvailable.
And DEMAND.onDataAvailable finishes before DEMAND.request to be able to
update the demand field then a request for reading will be lost.
Transition from READING->NO_DEMAND:
readAndPublish() returns false because there is no demand but before
switching the states READING.request is invoked again a request for
reading will be lost.
Changing READING->DEMAND/NO_DEMAND is made conditional so that the
operations will be executed only if changing states succeeds.
When in READING state detect completion before each next item in order
to exit sooner, if completed.

- Ensure completion signal (normal/exception) will be delivered to
the subscriber when transition from UNSUBSCRIBED->COMPLETED
- According to the specification "Publisher.subscribe MUST call onSubscribe
on the provided Subscriber prior to any other signals to that Subscriber" so
ensure onComplete/onError signals will be called AFTER onSubscribe signal.

This commit changes the implementation of the PathPattern
extractPathWithinPattern method that used an old AntPathMatcher
derivative to a new version that integrates more closely with
PathContainer.
It also introduces consistency in a couple of areas. The javadoc
is updated to specify this but basically:
- the response from the extra method will have all leading
and trailing separators removed.
- the response will have multiple adjacent separators within the
reponse reduced to just one. (For example response would be
aaa/bb/cc and not aaa///bbb//cc)
If your response would start or finish with multiple separators, they
are all removed.

- When there is no demand for reading, the implementation
should suspend reading otherwise useless events will be
send by Undertow to the registered read listener.
- There is not need to wait for an event for reading/writing after calling
resumeReads/resumeWrites
Practically no changes to RxNetty for a year and efforts underway to
rebuild 0.6.x based on a current Reactor Netty base.
Aside from the extra time to run integration tests having two
Netty-based servers can also cause false alarms such as ByteBuf leaks
related to RxNetty.
Also remove ErrorDeferredResultProcessingInterceptor which was meant
to be package private to begin with as its peer
ErrorCallableProcessingInterceptor (also removed).
Includes fixes for invalid exception declarations in Mockito-based unit tests. Also includes FreeMarker 2.3.27, Commons Pool 2.4.3, JSON-P 1.1.2.

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
