Bill Paul 2c9d7bb779 server.c: When 'securenets' (actually TCP_WRAPPERS) is enabled, don't
syslog connections unless they were rejected. This helps save wear and
tear on the syslog facility in large networks with many clienst systems.

yp_svc.c: Be a little smarter about using sigaction() -- set the SA_RESTART
flag.

svc_run: Be doubly paranoid about killing off child processes. Do a flag
chack and a pid check before letting child 'threads' self-destruct.
