Update "enableMatrixVariables" and "ignoreDefaultModelOnRedirect" to
use the more conventional XML form "enable-matrix-variables" and
"ignore-default-model-on-redirect".

Both forms are now supported by `AnnotationDrivenBeanDefinitionParser`,
with newer names being defined in the 4.0 XSD and the older names
remaining in the 3.2 XSD.

Issue: SPR-11136

Update code to have a consistent number of new-line characters after
import statements.

Apply consistent styling to new classes introduced in Spring 4.0.

- Javadoc line wrapping, whitespace and formatting
- General code whitespace
- Consistent Assert.notNull messages

Fix a variety of typos throughout the project, primarily in
comments (javadoc or otherwise) but also in a handful of log messages
and a couple exception messages.

ISSUE: SPR-11123

Fix remaining Java compiler warnings, mainly around missing
generics or deprecated code.

Also add the `-Werror` compiler option to ensure that any future
warnings will fail the build.

This change avoid use of AntPathMatcher to extract URI template
variables when the lookup path is used as the best matching pattern.

Remove Javadoc linkplain to ExceptionHandler#value() from
AnnotationMethodHandlerExceptionResolver to work around JDK

Introduce base class AbstractMethodMessageHandler for
HandlerMethod-based message handling.

Add MessageCondition interface for mapping conditions to messages
with support for combining type- and method-level annotation
conditions, the ability to match conditions to messages, and also
comparing matches to select the best match.

The key contract is MvcUrls. An instance is automatically created with
the Spring MVC namespace and the MVC Java config but can also be easily
created in any configuration.

Some example tests can be found in DefaultMvcUrlsTests.

Issue: SPR-10665, SPR-8826

MvcUriComponentsBuilder allows creating URIs that point to Spring MVC
controller methods annotated with @RequestMapping. It builds them by
exposing a mock method invocation API similar to Mockito, records the
method invocations and thus builds up the URI by inspecting the mapping
annotations and the parameters handed into the method invocations.

Introduced a new SPI UriComponentsContributor that should be implemented 
by HandlerMethodArgumentResolvers that actually contribute path segments 
or query parameters to a URI. While the newly introduced 
MvcUriComponentsBuilder looks up those UriComponentsContributor instances 
from the MVC configuration.

The MvcUriComponentsBuilderFactory (name to be discussed - MvcUris maybe?) 
prevents the multiple lookups by keeping the UriComponentsBuilder 
instances in an instance variable. So an instance of the factory could 
be exposed as Spring bean or through a HandlerMethodArgumentResolver to 
be injected into Controller methods.

Prior to this commit, @ControllerAdvice annotated beans would
assist all known Controllers, by applying @ExceptionHandler,
@InitBinder, and @ModelAttribute.

This commit updates the @ControllerAdvice annotation,
which accepts now base package names, assignableTypes,
annotations and basePackageClasses.

If attributes are set, only Controllers that match those
selectors will be assisted by the annotated class.
This commit does not change the default behavior when
no value is set, i.e. @ControllerAdvice().

Issue: SPR-10222

Before this change, async result handling on controller methods failed
to observe type-level annotations annotations. The issue was never
noticed until we started supporting type-level @ResponseBody and the
@RestController meta annotation.

Issue: SPR-10905

Includes revisions of MethodParameter and DependencyDescriptor (in particular towards a reference to the containing class). Also refines several ResolvableType method signatures.

Issue: SPR-9965

Prior to this commit, the template method createDataBinderFactory
would only allow ServletRequestDataBinderFactory as a return type.

This commit updates the method signature and allows
InitBinderDataBinderFactory, a superclass of the previous one.
Then other implementations can override this method and return
other InitBinderDataBinderFactory types.

Issue: SPR-10920

Refactor AbstractMessageConverterMethodArgumentResolver and
BridgeMethodResolver to use ResolvableType in preference to deprecated
GenericTypeResolver calls.

Comprehensive update to the framework's TimeZone handling, including a new TimeZoneAwareLocaleContext and a LocaleContextResolver for Spring MVC

A few noteworthy minor changes: LocaleContext.getLocale() may return null in special cases (not by default), which our own accessing classes are able to handle now. If there is a non-null TimeZone user setting, we're exposing it to all collaborating libraries, in particular to JSTL, Velocity and JasperReports. Our JSR-310 and Joda-Time support falls back to checking the general LocaleContext TimeZone now, adapting it to their time zone types, if no more specific setting has been provided. Our DefaultConversionService has TimeZone<->ZoneId converters registered. And finally, we're using a custom parseTimeZoneString method now that doesn't accept the TimeZone.getTimeZone(String) GMT fallback for an invalid time zone id anymore.

Renamed ResourceUrlMapper to ResourceUrlGenerator and refactored it
to be configured with Resource-serving HandlerMappings as opposed to
having them detected in the ApplicationContext through the
BeanPostProcessor contact.

Renamed and polished ResourceUrlEncodingFilter to ResourceUrlFilter
and added tests.
