Environment: Hibernate CVS head of branchv21 nov 25

Description:
Here is a patch allowing unsaved value for version. This is useful for saveOrUpdate() assigned id and having version as primitive type.

Version unsaved-value can be:
* undefined: let the saveOrUpdate choice to id's unsaved-value
    this is the default to prevent mapping break down primitive type version)
* null: save if version==null, update otherwise
* negative: save if version < 0, update otherwise (allowed for short, int, long only)

Timestamp unsaved-value can be:
* null: I think this is the only needed behavior. I don't know how undefined could be useful.
