This patch migrates the sysklogd project to use the modern /dev/kmsg
interface on Linux. There are many advantages over the older /proc
interface; 1) no need to wait for /proc to be mounted, 2) it provides
multiple simultaneous access. For more information, see:

Add missing -r option for log rotation and remove -8 option, which we
don't have yet.
Add SECURITY, DEBUGGING, and SIGNALS sections and expand upon the BUGS
section a bit to link things together.

This patch replaces the original man pages by Greg and Martin, that were
both licensed under the GNU GPL, with 3-clause BSD licensed versions of
the same man pages from FreeBSD.

- syslog.conf.5 FreeBSD Subversion r314436

This patch removes one of the traditionally key pieces of the sysklogd
project, klogd. Now that syslogd performs logging of kernel messages
we no longer require a separate daemon for that.

- We have the -a PEER and -s to limit exposure to remote attacks
- Mention include file syntax in .conf file differences section

This patch re-adds the -n flag, but now to disable DNS reverse-query for
all incoming messages. This can potentially speed up logging a lot for
small/embedded systems that act as log sink.

This change will probably break most installations. We do this to free
up '-n' for use as disabling DNS lookups, from FreeBSD *and* NetBSD.

Most of the functionality in syslogd is now up to par with NetBSD and
FreeBSD syslogd. Lots of syklogd project features have been removed and
syslog in itself is nothing new and surprising, so much of the text can
be greatly simplified or just removed.

Now that we've dropped the previous -r flag we can rename the rotation
flag so it's the same between both logger and syslogd.

This patch is inspired, in part, by FreeBSD syslogd but now diverges
onto its own path. Special handling for AF_UNIX sockets are required
on Linux, which unlike BSD cannot use getaddrinfo() on UNIX sockets.
- Rip out old funix[] and finet support
