This commit also removes nullability from two common spots: ResolvableType.getType() and TargetSource.getTarget(), both of which are never effectively null with any regular implementation. For such scenarios, a non-null empty type/target is the cleaner contract.

Beyond just formally declaring the current behavior, this revision actually enforces non-null behavior in selected signatures now, not tolerating null values anymore when not explicitly documented. It also changes some utility methods with historic null-in/null-out tolerance towards enforced non-null return values, making them a proper citizen in non-null assignments.
Some issues are left as to-do: in particular a thorough revision of spring-test, and a few tests with unclear failures (ignored as "TODO: NULLABLE") to be sorted out in a follow-up commit.

This commit introduces a `writableChannel()` method to
`WritableResource`, defaulting to `Channels.newChannel`, but with
overrides for file-based resources.
- Fixed AnnotationUtils.getValue() operation to ensure it re-throws AnnotationConfigurationException instead of swallowing it (as it is done in few other operations in AnnotationUtils)
- Added test
- Removed unnecessary '@SuppressWarnings("unchecked")'

StringDecoder can be created in text-only vs "*/*" mode which in turn
allows a more intuitive order of client side decoders, e.g. SSE does
not have to be ahead of StringDecoder.
The commit also explicitly disables String from the supported types in
Jackson2Decoder leaving it to the StringDecoder in "*/*" mode which
comes after. This does not change the current arrangement since the
the StringDecoder ahead having "*/*" picks up JSON content just the
same.
From a broader perspective this change allows any decoder to deal with
String if it wants to after examining the content type be it the SSE
or another, custom decoder. For Jackson there is very little value in
decoding to String which works only if the output contains a single
JSON string but will fail to parse anything else (JSON object/array)
while StringDecoder in "*/*" mode will not fail.

CharSequenceEncoder now supports all MIME types, however since encoding
Flux<String> can overlap with other encoders (e.g. SSE) there are now
two ways to create a CharSequenceEncoder -- with support for text/plain
only or with support for any MIME type.
In WebFlux configuration we insert one CharSequenceEncoder for
text/plain (as we have so far) and a second instance with support for
any MIME type at the very end.

Currently the BOM versions are:
* reactor-core 3.0.6.BUILD-SNAPSHOT
* reactor-netty 0.6.2.BUILD-SNAPSHOT
This commit fixes as well a few deprecations in reactor-core.
This commit adds an overloaded DataBufferUtils.read method that operates
on a AsynchronousFileChannel (as opposed to a ReadableByteChannel, which
already existed). This commit also uses said method in the Resource
encoders, if the Resource is a file.
This commit *adds* the "intercepted" headers to the ClientHttpRequest,
as opposed to replacing them, which is what happened before this commit.

Prior to this commit, the org.springframework.tests.Assume class could
fail to load resulting in a NoClassDefFoundError if parsing of the
'testGroups' system property failed. This is because the parsing took
place while initializing a static field.
This commit addresses this issue by moving the 'testGroups' system
property lookup to a dedicated method that is lazily invoked upon
demand instead of eagerly when loading the Assume class itself.
In addition, when an error occurs, TestGroup.parse() now logs the
complete original value of the supplied test groups string instead of
potentially omitting the "all-" prefix. This results in more
informative error messages similar to the following.
java.lang.IllegalStateException: Failed to parse 'testGroups' system
property: Unable to find test group 'bogus' when parsing testGroups
value: 'all-bogus'. Available groups include:
[LONG_RUNNING,PERFORMANCE,JMXMP,CI]

This commit adds a DataBuffer Encoder and Decoder, and uses it in
the annotation-based processing model.
Note that these codecs are not used in the functional processing model,
since the BodyInserter/BodyExtractor already have methods for
writing/reading DataBuffers.
Issue: SPR-15148
Simplify getAdapterFrom/To into a single getAdapter method that looks
for an exact match by type first and then isAssignableFrom.
Also expose shortcut methods in ReactiveAdapter to minimize the need
for access to the ReactiveTypeDescriptor.
