Got a clue about the pesky "SYN" messages.

I must not have read libevdev's documentation well enough. Hopefully
this new approach will work better. The risk would be that the
conversion takes too long and properly handling all events leads to an
increasing lag between the physical and the virtual device. I should
probably add an option to let users indicate they would prefer dropping
missed events.
