ACK series.

I have only one thing to mention, but it's not in scope of this series, it's
an existing behavior.  If you define a new guest with mouse/keyboard input
device with bus!=ps2 and graphics is defined, then we always add implicit mouse
and keyboard with bus=ps2 which leads to having two different mouses and
keyboards defined for the guest.  We should probably update the code to not add
any implicit mouse or keyboard if there is already one.
