Expand keycode to 'int' from 'short'

This uses the four high bits for the meta and control key sequences.
This means that we will be limiting our Unicode space to 28 bits, but
that's more than we really need.

It *would* be nicer if we just used the sign bit to mark "we have meta
character information") but that would require bigger changes.  And we
really don't need to worry about 30-bit unicode.  Small steps, remember.
