Aaron Zang 15ca3312c0 Solaris: Avoid switching to inactive VT's
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.
