Use ReverseListIterator instead of Stream API to reduce overhead. ListIterator provides means to iterate backwards so we're wrapping the existing iterator.
See #2857.

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.
