gnumach, new device 2?

[Alfred M. Szmidt]

This should be merged with `gnumach, new device' from the looks.  No
need to make lots of small patches that all depend on each other.
Explanation as always is needed (if there was one already, smack us
over the head with it).

        * conf.c: New "io" device.
