moving things around to use difftest proper
oops no checkin while I was working on it, bunches of changes
things
removingn results, and some sse tests
getting the 1000_rows_render test over to ws
switching pass to use the difftest directory
switching the file test to be ws
more tests converted to ws
redoing all the tests, starting the drop of all non WS transports
driver swizzle for sanity (adding execute) and more cleanup of tests since we've dropped the other transports
