Patch info for syslog_fac_olc

Author Comments

I needed stunnel to log to the MAIL facility in order to get
stunnel-wrapped imap to work correctly with my homegrown
imap-before-SMTP antirelay solution for sendmail 8. For a few
iterations, I just rebuilt stunnel with a modified log.c for each
install, but it has occurred to me that for similar reasons others
might want to change the syslog facility to which stunnel writes.
Inspired vaguely by sshd's SyslogFacility configuration parameter,
I've hacked in some code to allow runtime specification of log
facilities.

Attached is a diff against stunnel-3.8p4 which adds a new
commandline option ("-F") which accepts a syslog facility (e.g.
"mail", "DAEMON") as a parameter. I've tested this under linux 2.2.16
and OSF1 (aka Digital Unix/Compaq Tru64/whateverthehellitisthisweek)
V4.0 878. Insofar as those two are concerned it seems to work.
