Preserve multi-touch slot state when resetting input mappers
The existing pattern in InputReader is that when a mapper is reset, all
of its state is cleared and state of the buttons/axes is
queried through EventHub to rebuild the current state of the mapper.
This approach does not work for multi-touch devices, since there is no
way to query the current state of the contacts through the evdev
multi-touch protocol.
Since we cannot fully rebuild the current state of a multi-touch device,
we work around this limitation by never clearing the multi-touch state.
