Modified files:
	usr.sbin/syslogd: Makefile syslogd.c 
Added files:
	usr.sbin/syslogd: privsep.c privsep_fdpass.c syslogd.h ttymsg.c 

Log message:
Privilege separated syslog daemon. The child listening to log requests drops to user _syslogd and chroots itself, while the privileged parent grants it access to open logfiles and other calls it needs.

The only difference from existing behaviour is that if syslog.conf changes and syslogd receives a HUP, it will re-exec itself and have two new PIDs. A HUP with an unchanged config will make syslogd reopen logfiles as before.

Lots of help and code from deraadt@ , and advice from millert@
