Note that it does NOT return an error in this case, which still makes us
different from it (and SunOS4, and Ultrix, and DU4) if we follow this

I really think we should also swallow the error there.

Thats fine with me.
To summarize, I would
- fix sysctl so that it returns the truncated string, non-null-terminated,
and create an appropriate error. I think copyoutstr will do the job nicely
- fix gethostname/getdomainname so that if ENAMETOOLONG is returned from the
above, it will restore the old errno and null terminate the string
