bde 0a08034172 Don't use pessimal (u_short) types for i/o ports. This is mainly for
completenss.  The pessimization is tiny compared with i/o port slowness
except on very old machines, but code that used signed short types for
i/o ports was unpessimized long ago, and the macro that detected it
recently started working for u_short types too.  Use of bus space
should have made this moot long ago.
