unifying relationship name generation
Repository: cayenne
Updated Branches:
refs/heads/master 2dc30c8a1 -> 21675e4df
CAY-2133 ObjectNameGenerator refactoring - unifying relationship name generation
* getting rid of legacy generator. Can't support it anymore.
* building common obj and db rel name algorithm that works based on a collection of joins

UPGRADING TO 4.0.M4
+* Per CAY-2133, LegacyObjectNameGenerator is no longer provided, as it wasn't possible to maintain it in a fully backwards-
+ compatible manner. Embrace the new naming scheme, or provide your own ObjectNameGenerator if you absolutely need the
+ old names.
+
* Per CAY-2125 we no longer inject SchemaUpdateStrategy directly. Instead SchemaUpgradeStrategyFactory is injected.
If you have your own modules with SchemaUpdateStrategy injection, it will be ignored. So please review your
DI code and update it to use SchemaUpgradeStrategyFactory (or likely its subclass).
