This commit introduces the following changes.
1) It adds a new Spring @NonNull annotation which allows to apply
@NonNullApi semantic on a specific element, like @Nullable does.
Combined with @Nullable, it allows partial null-safety support when
package granularity is too broad.
2) @Nullable and @NonNull can apply to ElementType.TYPE_USE in order
to be used on generic type arguments (SPR-15942).
3) Annotations does not apply to ElementType.TYPE_PARAMETER anymore
since it is not supported yet (applicability for such use case is
controversial and need to be discussed).
4) @NonNullApi does not apply to ElementType.FIELD anymore since in a
lot of use cases (private, protected) it is not part for the public API
+ its usage should remain opt-in. A dedicated @NonNullFields annotation
has been added in order to set fields default to non-nullable.
5) Updated Javadoc and reference documentation.

Prior to this commit, HTTP Range requests were only supported by the
ResourceHttpRequestHandler when serving static resources.
This commit improves the `HttpEntityMethodProcessor` and
the `RequestResponseBodyMethodProcessor`. They now extract
`ResourceRegion`s from the `Resource` instance returned by the
Controller and let the Resource-related message converters
handle the writing of the resource (including partial writes).
Controller methods can now handle Range requests for
return types that extend Resource or HttpEntity:
@RequestMapping("/example/video.mp4")
public Resource handler() { }
@RequestMapping("/example/video.mp4")
public HttpEntity<Resource> handler() { }

This commit applies the Dependency Management Plugin to modules that
require it; right now Spring Framework is importing BOMs for Netty and
Reactor dependencies only.
Instead of applying those BOMs to all modules, they're applied only
where they're needed.

The main `build.gradle` file contains now only the common build
infrastructure; all module-specific build configurations have
been moved to their own build file.
Issue: SPR-15885
Includes general streamlining of dependency declarations with reduced version variables, direct use of EclipseLink 2.7 and its implicit JPA 2.2 dependency in spring-orm, mixed use of Hibernate 5.2.10 and 5.1.10 for integration tests, as well as an upgrade to Jetty 9.4.7 RC0 and a downgrade to Groovy 2.4.12 (since Groovy 2.5 won't be final in time for Spring Framework 5.0).

StandardMultipartHttpServletRequest now properly decodes RFC-5987
encoded filenames (i.e. filename*) by delegating to ContentDisposition
and also support RFC-2047 syntax through javax.mail MimeUtility.

This commit updates BeanUtils class in order to add Kotlin optional
parameters with default values support to the immutable data classes
support introduced by SPR-15199.
Issue: SPR-15673
This commit ensure that null-safety is consistent between
getters and setters in order to be able to provide beans
with properties with a common type when type safety is
taken in account like with Kotlin.
It also add a few missing property level @Nullable
annotations.
Issue: SPR-15792
ContentNegotiationManagerFactoryBean now provides an option to
explicitly set the strategies to use vs customizing a fixed
list of default strategies.

This commits extends nullability declarations to the field level, formalizing the interaction between methods and their underlying fields and therefore avoiding any nullability mismatch.
Issue: SPR-15720
Supporting ScriptEngine#eval(String, Bindings) when no render function
is specified allows to support use cases where script templates are
simply evaluating a script expression with an even more simplified
configuration.
This improvement also makes it possible to use script engines that
do not implement Invocable.
