This turned into a rather huge affair since it led to the introduction of a new AutowireCandidateResolver implementation in the spring-context module. That ACR impl is now being set through AnnotationConfigUtils; GenericApplicationContext and co do not set a default QualifierAnnotationAutowireCandidateResolver anymore (which has always been a smell anyway). At the same time, dependency ordering has moved from AutowiredAnnotationBeanPostProcessor to DefaultListableBeanFactory itself through a "dependencyComparator" strategy, applying to constructor dependencies and lazy resolution proxies as well.

Previously the method signatures for includes and isCompatibleWith were
incompatible with Spring 3.2.x since the argument was now MimeType.
This caused NoSuchMethodError to be thrown when a class was compiled
against MediaType from Spring 3.2.x and ran against MediaType
from Spring 4.x.
This commit restores the signatures and implements each method by
invoking the super class method.

Added AsyncRestTemplate, the asynchronous counterpart to the
RestTemplate that was introduced in Spring 3. All methods on the
AsyncRestTemplate are similar to those found on the synchronous
RestTemplatem, except that they return Future wrappers instead of
concrete results.
To enable this, this commit introduces the AsyncClientHttpRequest and
AsyncClientHttpRequestFactory, similar to the ClientHttpRequest and
ClientHttpRequestFactory, except that ClientHttpRequest returns a
Future<ClientHttpResponse> for the execute method. Two implementations
of these interfaces are provided, one based on the HttpURLConnection
incombination with a Spring AsyncTaskExecutor and one based on Apache
HttpComponents HttpAsyncClient.

ResourceHttpMessageConverter tries to use the filename to determine the
media type, but for Resource implementations such as ByteArrayResource
it is null, which causes NullPointerException. The fix checks whether
getFilename returns null before attempting to determine the media type
by it.

Although ServletHttpRequest provides access to Cookies, other
implementations may not. At the moment this was only needed
for SockJS to check the value of the JSESSIONID cookie. This
is now down by parsing the raw cookie values locally.
If comprehensive cookie support is to be added, we should
probably consider HttpHeaders as a potential candidate.
Also, StandardReflectionParameterNameDiscoverer calls "Parameter.isNamePresent()" now to return null (and pass on to the next discoverer) if no JDK 8 parameters are available. Note that this requires OpenJDK 8 b100 or higher to compile now.

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.
Issue: SPR-8032
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.
Issue: SPR-10485
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.
