Prior to this commit, the ShallowEtagHeaderFilter did not use the
content length given by the content generator to set the
ByteArrayOutputStream's buffer size.
This can lead to performance issues for large content since the buffer
grows as the content is being written.
This commit adds a new ByteArrayOutputStream variant called
ResizableByteArrayOutputStream. This implementation has public methods
for modifying the internal buffer size and does not synchronize on
buffer access.
This commit also make use of this new variant in
ShallowEtagHeaderFilter.

Since HttpClient 4.3, custom configuration such as the connection
timeout and the socket timeout are set in a RequestConfig object
stored in the HttpContext.
Unfortunately, older HttpClients are not supporting this
infrastructure and new clients throw an exception when the
deprecated API is used.
This commit detects if the client is an "old" implementation and
set the configuration through the deprecated means to restore
full backward compatibility with these features.

After this change, AbstractSockJsService does not add CORS headers if
the response already contains an "Access-Control-Allow-Origin" header.
Essentially it backs off assuming CORS headers are handled centrally
e.g. through a Filter.
In order to support this, the ServletServerHttpResponse now returns an
instance of HttpHeaders that also provides access to headers already
present in the HttpServletResponse.

Allow Jaxb2RootElementHttpMessageConverter subclasses to customize
the {@link Marshaller} and the {@link Unmarshaller} created by the
message converter.

Prior to this commit, all 2xx HTTP responses were eligible for ETag
generation in ShallowEtagHeaderFilter. In some cases, this would use
CPU resources for no reason since HTTP clients would not use ETags.
This commit is an optimization and restricts ETags generation in cases
where (all conditions must be met):
- response has a 2xx status
- request is a GET
- response does not contain "no-store" in its "Cache-Control" header

Before this change, issues surrounding the use of @Controller's in
combination with AOP proxying, resulted in an IllegalArgumentException
when trying to invoke the controller method.
This change detects such cases proactively and reports them with a
clear recommendation to use class-based proxying when it comes to
@Controller's. This is the most optimcal approach for controllers
in many respects, also allows @MVC annotations to remain on the
class.
The documentation has also been updated to have a specific section
on @Controller's and AOP proxying providing the same advice.

Before this change the getPathWithinServletMapping method of
UrlPathHelper could not work properly when a default servlet mapping
(i.e. "/") was used in combination with urlDecode=false. The fact that
the getServletPath() method of HttpServletRequest always returns a
decoded path was getting in the way.
Although there is no way to check Servlet mappings through the Servlet
API, this change aims to detect the given scenario and returns the full
path following the context path thus avoiding URL decoding.
Note that the same can be achieved by setting urlDecode=false and
alwaysUseFullPath=true. However this change ensures that urlDecode
works properly without having to know that.
Issue: SPR-11101
Before this change MvcUriComponentsBuilder could not create a
UriComponentsBuilder for methods where the mapping has a URI variable
and no matching method argument for it.
For example a URI variable may be in the type-level mapping but not
all methods may have an @PathVariable argument for it.
This fix addresses the shortcoming such that MvcUriComponentsBuilder
expands the method argument values available to it and leaves remaining
URI variables to be further expanded via UriComponents.expand().

Prior to this commit, RestTemplate's constructors were all initializing
default HTTPMessageConverters. Its API provides a way to replace
those converters with custom ones, but default converters are already
defined and initialized at that point, which can be an issue in some
cases (performance, classpath...).
This commits adds a new constructor for RestTemplate with a list
of message converters as argument. With this new constructor,
default message converters are never initialized.
Issue: SPR-11351
Prior to this commit, parts of a multipart HTTP request could be
injected in @RequestPart and @RequestParam annotated arguments, when
using types:
* MultipartFile, Collection<MultiPartFile>
* javax.servlet.Part, Collection<Part>
This commits updates @RequestParam and @RequestPart argument resolvers
and now allows the array versions of those types:
* Part[]
* MultiPartFile[]
Note that the MockHtpServletRequest backing tests for standard
Servlets implementations now uses a MultiValueMap to store parts
(versus a simple hashmap).
Issue: SPR-11353
Stereotype annotations should support a 'value' attribute for
specifying the name of the Spring-managed component; however,
@RestController currently does not provide such an attribute.
This commit introduces a 'value' attribute in @RestController so that
developers can provide custom names for components annotated with
@RestController.
