After this change, java.util.Optional is supported with @RequestParam,
@RequestHeader, and @MatrixVariable arguments in Java 8. When Optional
is used the required flag is effectively ignored.

Before this change @ModelAttribute methods were not invoked in any
particular order other than ensuring global @ControllerAdvice methods
are called first and local @Controller methods second.
This change introduces a simple algorithm that selects the next
@ModelAttribute method to invoke by making a pass over all methods and
looking for one that has no dependencies (i.e. @ModelAttribute
input arguments) or has all dependencies resolved (i.e. available in
the model). The process is repeated until no more @ModelAttribute
methods remain.
If the next @ModelAttribute method cannot be determined because all
remaining methods have unresolved dependencies, the first available
method is picked anyway just as before, i.e. with required
dependencies created through the default constructor.
Examples in ModelFactoryOrderingTests.

This commit adds support to read and write JSON using the Google Gson
library. GsonHttpMessageConverter offers default Gson configuration, but
can be customized by using GsonFactoryBean. GsonFactoryBean includes
several convenience properties for configuring the internal GsonBuilder
and the resulting Gson object.
By default Gson converts byte arrays to JSON arrays instead of a Base64
encoded string. GsonBase64ByteArrayJsonTypeAdapter provides support to
read and write Base64 encoded byte arrays, and can be enabled in
GsonFactoryBean.
RestTemplate will enable GsonHttpMessageConverter only if Jackson 2 is
not found on the class path, because by default GsonHttpMessageConverter
supports the same media types as Jackson.

The newly added support for ResponseBodyInterceptor is a good fit for
the (also recently added) support for the Jackson @JsonView annotation.
This change refactors the original implementation of @JsonView support
for @ResponseBody and ResponseEntity controller methods this time
implemented as an ResponseBodyInterceptor.

This commit also includes lazy resolution support for StandardServletMultipartResolver, along the lines of existing lazy mode in CommonsMultipartResolver.
Issue: SPR-11074
Issue: SPR-11730
This feature required support for response exposure on Servlet/PortletRequestAttributes, instead of just in the Servlet/PortletWebRequest subclasses.

Spring MVC now supports Jackon's serialization views for rendering
different subsets of the same POJO from different controller
methods (e.g. detailed page vs summary view).
Issue: SPR-7156
This change adds a strategy for assigning a default name to an
@RequestMapping controller method. The @RequestMapping annotation
itself now has a name attribute allowing the explicit assignment
of a mapping name.
This is mainly intended for use in EL expressions in views. The
RequestContext class now provides a getMvcUrl method that internally
delegates to MvcUriComponents to look up the handler method.
See the Javadoc of MvcUriComponents.fromMappingName.
Issue: SPR-5779
This change refines the logic of "mapping" content negotiation
strategies with regards to how to handle cases where no mapping is
found.
The request parameter strategy now treats request parameter values that
do not match any mapped media type as 406 errors.
The path extension strategy provides a new flag called
"ignoreUnknownExtensions" (true by default) that when set to false also
results in a 406. The same flag is also exposed through the
ContentNegotiationManagerFactoryBean and the MVC Java config.

Animal sniffer provides tools to assist verifying that classes
compiled with a newer JDK are compatible with an older JDK.
This integratesthe latest version of the tool (1.11) that
permits the use of custom annotations. Added @UsesJava7,
@UsesJava8 and @UsesSunHttpServer and annotated the few places
where we rely on a specific environment.
The verification process can be invoked by running the 'sniff'
task.

polishing
Clean up compiler warnings in the tests of spring-web. This commit
adds type parameters to all the types (mostly `List` and `Map`).
After this commit the only warnings in spring-web left are in
* `MockExpressionEvaluator` this can't be fixed until JSP-EL is fixed
* `Jackson2ObjectMapperFactoryBeanTests#testSetModules` that code
would never compile with generics.
