Fix for OpenSolaris bug 6876992: "[vconsole] Ctrl+Alt+F12 switchs to blank
console screen with hotkeys property turned-off"
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6876992
Xorg needs to do sanity test for the VT it is commanded to switch to.
If the VT is not opened by any process, discard the switching request.
The changes also contain the fix for some flaws discovered when
getting the new gdm to run.
