This change enables having @ResponseBody on the type-level in which
case it inherited and does not need to be added on the method level.
For added convenience, there is also a new @RestController annotation,
a meta-annotation in turn annotated with @Controller and @ResponseBody.
Classes with the new annotation do not need to have @ResponseBody
declared on the method level as it is inherited.

MimeType is available in core-spring and does not include support
for quality parameters and media used in HTTP content negotiation.
The MediaType sub-class in org.springframework.http adds q-parameters.
The method returning query parameters now returns only query string
parameters as opposed to any Servlet request parameter.
This commit also adds a ReadOnlyMultiValueMap.
ServerHttpAsyncResponseControl wraps a ServetHttpRequest and -Response
pair and allows putting the processing of the request in async mode
so that the response remains open until explicitly closed, either from
the current or from another thread.
ServletServerHttpAsyncResponseControl provides a Serlvet-based
implementation.
A getCookies method is now available on ServerHttpRequest with one
ServletServerCookie implementation that wraps a Servlet cookie.
The SockJS service makes use of this to check for an existing session
cookie in the request.
- Added org.springframework.http.StreamingHttpOutputMessage, which
allows for a settable request body (as opposed to an output stream).
- Added http.client.HttpComponentsStreamingClientHttpRequest, which
implements the above mentioned interface, mapping setBody() to a
setEntity() call on the Apache HttpClient HttpEntityEnclosingRequest.
- Added a 'bufferRequestBody' property to the
HttpComponentsClientHttpRequestFactory. When this property is set to
false (default is true), we return a
HttpComponentsStreamingClientHttpRequest instead of a (request
buffering) HttpComponentsClientHttpRequest.

SPR-10402 in Spring Framework 3.2.3 treated empty request parameter
values as missing values, if the empty value was turned into a null
by a PropertyEditor or Converter. This caused the regression.

Similar to @ExceptionHandler but for message processing. Such a method
can send messages to both the message broker channel and the client
channel provided the client is subscribed to the target destination.
Prior to this commit the Spring Framework did not provide a public means
for scanning for available server ports. However, the Spring Framework
internally used a FreePortScanner in integration tests within its own
test suite. Furthermore, Spring Integration 2.2 provides similar support
in a SocketUtils class in the spring-integration-test module.
This commit introduces SocketUtils in spring-core to replace the
FreePortScanner which was previously only used internally within
Spring's test suite. This new implementation is inspired by both Spring
Framework's FreePortScanner and Spring Integration's SocketUtils and
consequently attempts to merge the best of both previous
implementations.

Previously DeferredResult locked around the setting of the result
including handling up to the part of submitting a dispatch. This
can cause a deadlock if a timeout occurs at the same time since
the Tomcat timeout thread has its own locking that permits only
one thread to do timeout or dispatch processing.
The fix reduces the locking to cover only the attempt to set the
DeferredResult but not the dispatching.

Spring 3.2.2 introduced a change to avoid closing the response stream
in HttpMessageConverters (SPR-10095). However, the InputStream of
resources being written, for example as part of a multi-part request
should be closed. This change ensures that.
Issue: SPR-10460
If type conversion turns an empty request parameter value (i.e. "") to
null, we should treat it as a missing value. By default the
ConversionService doesn't change empty strings and therefore one must
explicitly convert them to null for example by registering a
StringTrimmerEditor with emptyAsNull=true.
Issue: SPR-10402
Previously ContentNegotiationManager continued with the next
ContentNegotiationStrategy only if the current one returned an empty
list. Now it also does that if the current ContentNegotiationStrategy
returns "*/*". Since the absence of an Accept header and "*/*" have
the same meaning, this allows a default content type to be used in
either case.
Issue: SPR-10513
Update ServletContextAwareProcessor to allow subclasses to support late
binding of the ServletConfig and/or ServletContext. Allows for the
post-processor to be registered before the servlet environment has been
initialized.
