When the plus operator is used between strings in a SpEL
expression and that expression is compiled, it is
important to include a cast if computation of any of
the operands isn't obviously leaving strings on the
stack. Likewise if the stack contents are known to
be strings, a cast should not be included.

Prior to this commit, range requests would be served by
ResourceHttpRequestHandler by partially reading the inputstream of
static resources. In case of resources contained in ZIP/JAR containers,
InputStreams may not fill the entire read buffer when calling
`inputStream.read(byte[])`. This was the case when using Spring Boot's
ZipInflaterInputStream - this would then not read the entire file
content and would close the response without writing the expected body
length indicated in the "Content-Length" header.
This commit makes sure that the whole resource is read.

This is needed in order to be able to use Spring Reactive in standalone
applications. These are temporary classes that will return in
src/test/java when Spring Boot support for Reactive applications will
be implemented.
Prior to this commit, when adding a ShallowEtagHeaderFilter to an
application, the ServletResponse would be wrapped by a
ContentCachingResponseWrapper. When any part of the Spring
infrastructure calls `flushBuffer` on the wrapped response, the call is
delegated to the actual response, which is committed. It's not possible
to alter the response (headers, content) anymore - the ETag filter can't
act.
This change prevents the `flushBuffer` call to be delegated and only
commits the underlying response once the cached content is copied to the
actual response stream.

With this change the MapAccessor now extends CompilablePropertyAccessor
rather than just PropertyAccessor. This means that any expression that
ends up using the MapAccessor is now compilable for fast performance.

reactive.codec -> core.codec
reactive.io -> util
These may very well not be the final locations. For now they simply
express that there are classes that belong somewhere in core, i.e.
they are lower level dependencies than web.
RequestMappingHandlerMapping currently picks the first match and does
have logic to deal with selecting the best match. This caused a
random test failure depending on which controller method was matched
first. This change removes the test.
The web related code is now under org.springframework.web.reactive.
This is parallel to org.springframework.web (the top-level package of
spring-webmvc).
This change allows to be able to check generic type on the return value
at HandlerAdapter and ResultHandler level. For example, it allows to do
a Publisher<Void> check in SimpleHandlerResultHandler.
"Content-Type" is just a single MediaType.
For the response, the MediaType must be fully selected before
selecting and encoder.
The ResponseBodyResultHandler now includes actual content negotiation
with a potential 406 response.
This commit introduces the following changes:
- MessageToByteEncoder/Decoder renamed to Encoder/Decoder
- JsonObjectEncoder/Decoder are now used directly in
JacksonJsonEncoder/Decoder
- Codec uses MimeType instead of MediaType since they
are not specific to HTTP
- Default MimeType are now managed thanks to
Encoder/Decoder#getSupportedMimeTypes()
- AbstractEncoder/Decoder takes care of generic MimeType related behavior
