3.0 - Fix pagination in Sqlserver2008

This re-adds the subquery flavour of pagination required by SQLServer <= 2008. I've also updated the wincache tests so they don't fail when `wincache.enablecli` is off.

I wasn't able to run all the test cases due to errors elsewhere in the suite but the database and ORM package tests all pass.
