Hibernate ORM 6 preparations, batch 1

[Sanne]

To pave the road to Hibernate ORM 6 I'll be sending a series of small changes which should not have an impact on existing usage; the intent is to already remove support for deprecated things in advance and in smaller steps.

The secondary intent is to keep the module from needing a substantial rewrite on the day we'll switch to ORM 6; I expect it still will be rather substantial but tryint to limit it to some controllable size.
