Patch to remove connection hook and JDK 1.3 dependencies

Attached is a patch to remove the ConnectionHook functionality and thus
the JDK 1.3 dependency.  For a further explanation see my posting to the
JDBC list on Friday, explaining why this is being done.

thanks,
--Barry

PS.  In addition to the diffs in this patch, the file
src/interfaces/jdbc/org/postgresql/core/ConnectionHook.java is obsoleted
and needs to be removed from 7.2, but of course the file is still needed
for 7.1 builds.
