r8219: Merge the new open code from HEAD to 3.0. Haven't yet run the torture

tests on this as it's very late NY time (just wanted to get this work

Jerry - in looking at the difference between the two trees there
seem to be some printing/ntprinting.c and registry changes we might
want to examine to try keep in sync.
Jeremy.
