* syslog.cc (try_connect_syslogd): Add priority parameter. Use writev

Browse Source 
to add the priority to the message in a syslog conformant way.
	(vsyslog): If facility isn't set in the priority, use default facility
	as given in call to openlog. Fix agressive use of spaces in syslog
	output. Call try_connect_syslogd with priority parameter.
