We now treat CrudRepository.saveAll(…) properly by unwrapping the given *Iterable*. This previously already worked for collections handed into the method but not for types only implementing Iterable directly (like Page or Window).
Fixes#3153.

SpelEvaluator now iterates over the parameter map instead of using the Java 8 Stream API. Previously, expressions resulting in a null value failed in the collector as Java 8 streams require non-null values for map values.
Closes#2904
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
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.
