        src/include: unistd.h

Log Message:
The gethostname() function is (from when it was added to POSIX)
a base function, not an XSI optional extension, so it should be
made visible whenever _POSIX_C_SOURCE is >= 200112 (Posix Issue 6),
and not only for _XOPEN_SOURCE >= 600 (which would be for an XSI
function added then).

Move the prototype for gethostname() to the right section of the file.

Note this makes the visibility of gethostname() wider, it will remain
visible everywhere it was visible before - the only conceivable issue
would be if someone was abusing the name in a context where they
shouldn't be.  (Some non NetBSD application, as all of NetBSD is
compiled with _NetBSD_SOURCE defined, everything tends to be visible,
so no change at all for the NetBSD source tree).
