* Switch from the "expression" to "expressionOrPredicate" rule in the HQL grammar where it makes sense as required by some HQL tests
* Cleanup parser rule ordering to allow more keywords in the identifier rule
* Implement literal support for Ordering parser
* Add special AvgFunction as needed by H2, HSQL, DB2, SQL Server and Sybase that casts arguments to double if necessary
* Fix wrong deduplication of order by fragments in case a plural attribute is fetched multiple times
* Implement support for de-referencing any-valued mappings in HQL
* Avoid unnecessary entity subtypes in polymorphic splitted queries if a base type also matches the requested type
* Implement pagination support for polymorphic splitted queries
* Cleanup path part resolving by removing lots of duplicate code
* Aligh HQL parsing expectations to the expected behavior of 5.x
* Add method to `JavaType` that allows determining if a type is can be widened to another which is used for arithmetic type resolving
* Implement validations for fetch owner checking
* Fix issues with the id table creation due to lacking column lengths in the column DDL type
* Fix issues and add some optimizations related to multi-table delete handling
* Add the notion of a special "implicit" alias to avoid generating a unique alias for unaliased or implicit HQL joins
* Properly implement multiple bag fetch validation
* Make sure filter predicates are applied for all plural attribute joins
* Fix some issues with undecidable parameter type inference
* Fix some issues with negated SQM predicates not being converted to the proper SQL AST predicates
* Fix issues with qualifying DML target referencing columns
* Fix `is null` semantics for tuples referring to embeddable types
* Capture necessary details from JdbcValuesMetadata in the cached data to avoid executing a query on cache hit when types should be inferred
* Get rid of special CollectionPropertyNames and writeup a migration guide section for the replacements
* Get rid of unnecessary whitespace and optional keywords in generated SQL
* Handle some type inference related issues with some databases requiring to render casted parameters in some situations
* Ensure SQM model is fully serializable
* Ensure JPA Criteria throws expected exceptions
* Make sure JPA Criteria implementations work properly
* Move jpa.test.callback and jpa.test.criteria packages
* Improve the reuse of SqmPath instances
* Get rid of many raw-types related warnings
* Make Predicate extend Expression and handle SQL rendering/emulation
* Support fetching SqmTuple as array
* Implement treat operator support
