Allow nullable OffsetScrollPosition and add support for values wrapped within Optional.
Update tests. Reformat code. Add issue tags to tests.

Use ReverseListIterator instead of Stream API to reduce overhead. ListIterator provides means to iterate backwards so we're wrapping the existing iterator.

We now use the merged bean definition to resolve the defined EntityCallback type.
Previously, we used just the bean definition that might have contained no type hints because of ASM-parsed configuration classes.
Closes#2853
When binding values to collection-like paths, we now unwrap potentially double-wrapped collections as QuerydslPredicateBuilder attempts to convert the binding value to the type of the path.
Our default is a contains binding for single elements.
Closes#2834
We now reduce allocations of DefaultMethodInvokingMethodInterceptor by reusing DefaultMethodInvokingMethodInterceptor within a ProxyProjectionFactory. We also reduced allocations during default method discovery and reuse the default methods information within the projection information cache.
Closes#2831
Moved general-purpose factory methods to the common ScrollPosition interface. Introduced a couple of domain specific methods to conveniently work with both Keyset- (to e.g. change direction) and OffsetScrollPosition (to e.g. advance the offset). Consolidated unit tests accordingly.
Moved WindowIterator to ….data.support package. Fixed case of Direction enum values.
Fixes#2824.
We should change the definition of `PersistentPropertyPath` to — in its public API — not allow empty instances anymore. Those violate the concept and bleed into the concept's API by having to make all methods nullable (returning null in exactly that "empty" case). An empty property path doesn't make any actual sense as you cannot reasonably answer the methods declared on the interface except by returning null, which then causes client code having to verify the returned values all the time.
This is now changed into only making `PersistentPropertyPath.getParentPath()` nullable and letting it return null for single segment paths. Adapted client code accordingly. `….getRequiredLeadProperty()` is now deprecated in favour of `….getLeafProperty()` not returning null anymore.
Fixes#2813.
In case an EntityCallback is declared as lambda expression, the JVM does not expose any generics information about the target entity type the callback shall be applied to. This commit changes the callback lookup and processing so that in case the generics information is not detectable on the type, we fall back to the BeanDefinition's resolvable type (fed by the factory method's return type which carries the necessary reflection information). That generics information is then kept in the newly introduce EntityCallbackAdapter and the code inspecting the actual entity type for matches then uses the resolvable type held in that. Also, the actual callback invocation is done on the adapter's delegate.
Removed the ability of the discoverer to register EntityCallbacks by bean name as that was not used in the public API at all and it avoids duplicating the bean definition type detection. A couple of minor additional cleanups (records for cache key, methods static where possible and with lower visibility etc.)
Fixes#2812.
The intend of WindowIterator is to support users who need to iterate multiple windows. It keeps track of the position and loads the next window if needed so that the user does not have to interact with the position at all.
Also remove the Window methods to get the first/last position and enforce the index based variant.
Update the documentation to make use of the newly introduced API.

Imports, Javadoc, ticket references in test cases.
Removed the need for MethodParameterAware… flavors of the ResourceAssemblers by keeping the MethodParameter reference in the original assemblers in the first place. Extracted common Pageable MethodParameter lookup code into PageableMethodParameterUtils.
Related ticket: #1307.
Added SlicedResourcesAssembler to esaily convert Slice instances into SlicedResource instances and automatically build the required previous/next link based on PageableHandlerMethodArgumentResolver present in the MVC configuration. The assembler can either be injected into a Spring MVC controller or a controller method. The latter will then assume the controller methods URI to be used as pagination link base.
Added necessary SlicedResourcesAssemblerArgumentResolver and MethodParameterAwareSlicedResourcesAssembler classes and wire up HateoasAwareSpringDataWebConfiguration configuration beans to that SlicedResourcesAssembler's can be auto-injected into controllers.
Closes#1307
Use consistently domain type instead of introducing a new terminology to repository infrastructure.
Rename Kotlin variant of ParameterUnitTests to KParameterUnitTests to avoid duplicate classes.

To support the binding of Class parameters to queries for declared query methods, we have to be able to differentiate them from Class parameters that are supposed to represent projections. We can do that by relating the declared Class' element type to the aggregate root type as a Class typed to that or any subtype of it will never trigger a projection by definition.
So far the Parameter(s) abstraction was solely created from a query method's Method. We now changed that for QueryMethod to forward the aggregate type detected on the RepositoryMetadata and consider it during the detection of dynamic projection parameters.
As a mitigating measure, we now also support @Param on Class-typed parameters to explicitly mark them for query binding. This is primarily to be able to add this support to the 2.7
The changes are built in a way that modules extending that mechanism will continue to work as is but see deprecation warnings on methods and constructors involved. Adapting extending code to the new APIs will automatically enable the support for bindable Class parameters on query methods.
Fixes#2770.
