Initial restructuring to add jdbc3 support. There was a significant amount

of duplicated code between the jdbc1 and jdbc2.  This checkin restructures
the code so that the duplication is removed so that the jdbc3 support
can be added without adding yet another copy of everything.  Also many
classes were renamed to avoid confusion with multiple different objects
having the same name.  The timestamp tests were also updated to add support
for testing timestamp without time zone in addition to timestamp with time zone
