- added multiple services in the same configuration file
- added SO_PEERCRED linux support
- other improvements (see ChangeLog)
-----

configuration file is changed in order to support multiple suipfiles:
every configuration is in the form:

label {
	parameters
}

default is assigned for default entries
options is assigned for general daemon options

example
[sud.conf]
options {
	daemonize = yes
	pidfile = /var/run/sud.pid
	emergency = "login -f root"
}

default {
	terminal = vt100
}

ilogin {
	suipfile = "/usr/sbin/ilogin"
	mode = interactive
	dologin = yes
}

passwd {
	suipfile = "/usr/bin/passwd"
	mode = command
	setuser = $myuid
	setgroup = $mygid
	seteuser = root
}
