Aligned with general request attribute naming conventions and prefixed the one we now use with the class' name. Altered the local attribute name to EFFECTIVE_REPOSITORY_RESOURCE_LOOKUP_PATH.
Renamed the constant holding the name from …_KEY to …_ATTRIBUTE.
We now expose a partially resolved PathPattern to contain the explicit repository base path so that the subpaths can be grouped around the individual repositories exposed.

MappedProperties now exposes a factory method that uses the Jackson introspector for serialization (instead of deserialization) which now also includes read-only properties. Previously, read-only ones were not considered as they are excluded from the metadata if it is looked up for deserialization.
We now support adding a to a collection via JsonPatch expressions by using the collection's size as target index. Contrary to paths pointing to existing collection elements we cannot determine the type of the object to be created. Thus, we fall back to the common element type of all existing collection elements. We also reject indexes pointing to elements with an index greater than the current collection's size.
Forwarding headers handling is now centralized in ForwardedHeaderFilter and removed from ServletUriComponentsBuilder. We need to filter requests containing forwarding with ForwardedHeaderFilter.
DomainObjectReader now aborts the recursive merges in case it encounters an entity that's described as @Immutable (just introduced in Spring Data Commons).
Fixed some generics and removed DomainObjectMerger as it's unused.

Adapted RepositoryRestMvcConfiguration to now create a shared fallback ObjectMapper and avoid to register it as Spring Bean. Adapted test cases that previously were relying on such a bean being present.
Adapted test cases to verify on the correct ALPS document structure (see spring-projects/spring-hateoas#665).
