    Short-cut the input device cleanup process during AbortServer() · 9f79e93b

    If we're about to abort, we're already in the signal handler and cannot call
    down to the default device cleanup routines (which reset, free, alloc, and
    do a bunch of other things).
    
    Add a new DEVICE_ABORT mode to signal a driver's DeviceProc that it must
    reset the hardware if needed but do nothing else. An actual HW reset is only
    required for some drivers dealing with the HW directly.
    
    This is largely backwards-compatible, hence the input ABI minor bump only.
    
    Drivers we care about either return BadValue on a mode that's not
    DEVICE_{INIT|ON|OFF|CLOSE} or print an error and return BadValue. Exception
    here is vmmouse, which currently ignores it and would not reset anything.
    This should be fixed if the reset is required.
