vt: add an event interface
This is needed and requested in various forms for ConsoleKit, screenblank handling and the like so do the job with a single interface. Also build the interface so that unlike VT_WAITACTIVE and friends it won't miss events. FIXME: Should this be a waitactive ioctl or a new device file you can poll and read events from. We need the code anyway to fix up the existing broken wait for console switch logic but the ConsoleKit people would prefer the new device to the ioctl we have here Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
