Unwrap/rewrap EnterVT/LeaveVT completely, Fixes 28998
Because some EnterVT code needs to remove it self from the call chain, we need to fix all of the wrappers to correctly unwrap/rewrap during the call chain. This is a follow-on to the fix for bug 27114 in commit 68a9ee8370e6f9b38218376ac92d5130a5b0ef1e.
