Revert "Send mapper events via context"

This reverts commit cec3f6a94b1cd510d6c2f7ef9935db95fa115297.

As we discussed with Chris and Michael, it is more natural to keep the
flow of inputreader -> inputdevice -> inputmapper -> inputlistener
rather than having to come back to inputreader.

This also reduces the redundancy of having to mimic the inputlistener
interface inside the inputreader context.
