[hibernate-dev] Backward compatibilty latest snapshot

[Steve Ebersole]

DialectFactory constituted a circular package dependency between
o.h.dialect and o.h.dialect.resolver.  It was moved to the
o.h.dialect.resolver package to alleviate that circularity (yes we have
tons of such circularity in Hibernate, but we have to start cleaning up
somewhere).  

Sadly, even that move really did not address the underlying
public/internal issue because o.h.dialect and its sub-packages still
contain a mix of public stuff and internal stuff.  I expect this to get
addresses again later but certainly not for 3.3 or 3.5.  Probably not
until 4.0
