Say hello to the new "net-mgmt" category. There are probably more
ports that belong here than the ones I have identified and moved in
this, first, pass.
Approved in principle by: marcus
Update to Argus-2.0.1. This commit closes ports/27562, though it is not based
on the patch offered (I already had prepared diffs more than one week ago, but
had no time to perform the commit). I choose to use my patches instead of
those from the PR, since they seemed even more correct ;-)
