MFC r283889,r283891:
Clear p_stops when doing PT_DETACH and PROCFS_CTL_DETACH. Without this, if a process was being traced by truss(1), which uses different p_stops bits than gdb(1), the latter would misbehave because of the unexpected bits. Reported by: jceel Submitted by: sef Sponsored by: iXsystems, Inc.
