Subject: [PATCH 03/14] Move COMPAT_ATM_ADDPARTY to net/atm/svc.c

This used to be behind an #ifdef COMPAT_COMPAT, so most of userspace
wouldn't have seen the definition before.  Unfortunately this header
file became visible to userspace, so the definition has instead been
moved to net/atm/svc.c (the only user).
