Try this; the attach patch appears to work with 1.4.11rc1, or at least
it doesn't fail like before, on snv_111b (after I patch 1.4.11rc1 to
actually build, see 124923). solookup and socreate behave differently
and appear to have differenet signatures than what the rxk code assumes.
Specifically, solookup was failing because it returns an error code, not
a vp, so it returns 0 on success, we interpret it as a NULL and a
failure, so it fails.

The AFS_SUN511_ENV in this is a bit coarse-grained if the old code
worked with previous releases of OpenSolaris. If someone knew when these
interfaces changed, that'd be helpful. Or we could have a configure test
for the new kernel sockets stuff, and try to use those.
