This commit expands the range of whitelisted extensions by checking
if an extension can be resolved to image/*, audo/*, video/*, as well
as any content type that ends with +xml.

Prior to this change, the HttpEntityMethodProcessor would try to process
conditional requests that are undefined by the spec, such as:
* an HTTP GET request with "If-None-Match:*"
* a request with both "If-None-Match" and "If-Match"
* a request with both "If-None-Match" and "If-Unmodified-Since"
This commit skips the processing of those requests as conditional
requests and continues with normal request handling.

Refine the approach of having <mvc:view-resolvers> detect and use the
ContentNegotiationManager instance registered with
<mvc:annotation-driven> introduced in the last commit.
Issue: SPR-13559
The <mvc:annotation-driven> element now adds an alias when a
ContentNegotiationManager bean is registered with a custom name.
This helps <mvc:view-resolvers> to more reliably find such a custom
ContentNegotiationManager.

Prior to this change, serving resources with ResourceHttpRequestHandler
could result in NPE when requesting an existing folder located in a JAR.
This commit swallows those exceptions, as it is not possible to foresee
those cases without reading the actual resource. This result in a HTTP
200 response with a zero Content-Length instead of a HTTP 500 internal
exception.
Issue: SPR-13620
This commit migrates all remaining tests from JUnit 3 to JUnit 4, with
the exception of Spring's legacy JUnit 3.8 based testing framework that
is still in use in the spring-orm module.
Issue: SPR-13514
This commit introduces a new ScriptRenderException in order to:
- Print in the resulting error page the reason of the script failure
- Not print the whole stacktrace in the logs
The ScriptRenderException thrown in ScriptTemplateView#renderMergedOutputModel()
is wrapped into a ServletException in order to avoid printing 2 times the messages in
the logs (throwing directly a ScriptRenderException would make it wrapped in a
NestedServletException that contains a getMessage() override not needed in this
context)

ResponseBodyEmitter now registers by default to receive callbacks
on timeout/completion and sets its internal "complete" flag to true
in order to prevent proactively further use of the emitter.
Issue: SPR-13498
Prior to this commit, HttpEntityMethodProcessor would process
conditional requests even if those aren't GET requests.
This is an issue for POST requests with "If-None-Match: *" headers and
many other use cases, which should not receive an HTTP 304 Not Modified
status in response.
This commit only triggers ETag/Last-Modified conditional requests bits
for GET requests.

Some converters (Jackson, Gson, Protobuf) already do this. It is now
also done in AbstractMessageConverterMethodArgumentResolver which
enforces a consistent behavior across controller method arguments.
Issue: SPR-12745
Also revised StandardScriptFactory for finer-grained template methods, added further configuration variants to StandardScriptEvaluator, and identified thread-local ScriptEngine instances in ScriptTemplateView by appropriate key.
Issue: SPR-13491
Issue: SPR-13487
This commit makes ThreadLocal<ScriptEngine> engineHolder ScriptTemplateView
field static in order to limit the maximum number of ScriptEngine instances
to the number of threads, regardless of the number of view instances.
Issue: SPR-13487
This commit introduces support for attribute overrides for
@ResponseStatus when @ResponseStatus is used as a meta-annotation on
a custom composed annotation.
Specifically, this commit migrates all code that looks up
@ResponseStatus from using AnnotationUtils.findAnnotation() to using
AnnotatedElementUtils.findMergedAnnotation().
