cursor-tracker: Use our own marshal for cursor-moved

Browse Source 
By putting `NULL` as the C marshaller in `g_signal_new`, you
automatically get `g_cclosure_marshaller_generic`, which will try to
process its arguments and return value with the help of libffi and
GValue.

Using `glib-genmarshal` and valist_marshallers, we can prevent this so
that we need less instructions for each signal emission.
