Slightly tweaked the configuration model to rather handle the CorsRegistry via RepositoryRestConfigurer.configureRepositoryRestConfiguration(…) rather than RepositoryRestConfiguration itself. That allows moving of Spring WebMVC as a dependency in the core module.
The original methods exposing access to the CorsRegistry are now still available in deprecated form to not break existing clients.
Follow-up ticket: DATAREST-1542.
We now use Spring's path prefix capabilities to apply Spring Data REST's base path to its mappings. This was previously implemented by tweaking the matching conditions.
We now also pick up Spring 5.3's PathPatternParser and apply that to the custom HandlerMapping implementations we register.
Moved DelegatingHandlerMapping into the configuration package to be able to keep it around in package scope.
Deprecated RepositoryRestConfiguration.getBaseUri() as we have only supported paths for quite a while now. Moved all client code to ….getBasePath() instead.
We now use the current request's URI as base link for all links created for a collection resource. This especially has effect in the creation of pagination links as we now carry potentially applied critierias (induced by our Querydsl based filtering support) forward to the navigation links generated.
Moved off Spring Framework deprecations for HttpMessageNotReadableException. This required some rearrangements of method signatures for types (hopefully) exclusively used by internal abstractions (some public, but not very friendly for user extension in the first place).
Switched to consistent use of Pageable.unpaged() instead of null. Switched to the use of new factory methods in Spring HATEOAS. Some Java 8 based improvements in request handling to simplify the implementation code. Deprecation of code that got obsolete due to the use of the factory methods.
Moved off some deprecations in Jackson APIs.
Removed a couple of unused imports. General avoidance of common warnings. Suppression where needed. Removed dead code in configuration.
The usage of text/uri-list as media type was entirely broken and not even advertised in the reference docs anymore. It's now again supported for both to-one and to-many associations via Collections. Maps are rejected as they cannot be rendered as list of URIs correctly. Updated reference documentation accordingly.
Added a custom MapModel implementation of RepresentationModel as apparently using Maps with EntityModel does not unwrap the content properly due to [0].

Correct a regression regarding association links. Introduce several test cases to prove this situation is fixed regarding PUTs for association links.
Source of the bug: 554d6cb27b (diff-1d7c16fe1992fef13a47fa8ab8599718L317) flips the criteria from "not single" to "single" without checking for related impacts.
We now rely on the MessageResolver capabilities of Spring HATEOAS to benefit of the optimizations in resource bundle resolution. Tweaked a couple of tests to make sure they properly use the resolver resorting to the default message the MessageResourceResolvable exposes.
We now enable CORS handling for all requests by overriding the newly introduced hasCorsConfigurationSource method. We cannot detect CORS configuration handling solely on the handler but require path headers to resolve repository interface mappings.
