Consume all available udev events at once
We get multiple udev events for actions like docking a laptop into its
station or plugging a monitor to the station. By consuming as many
events as we can, we reduce the number of output re-evalutions.
It depends on the timing how many events can be consumed at once.
(Inspired by xserver commit 363f4273dd4aec3e26cc57ecb6c20f27e6c813d8)
