e61e5abb88 Follow-up to 9856e07, rename '-K' option to '-t'
We need the '-K' option to disable kernel logging, so this option needs
to be renamed, unfortunately.  Fortunately it's not been released yet.

Issue #42

287e009514 Fix #35: syslogd man page lists -v as verbose mode, is version
When syncing with the FreeBSD man page the audit missed this option.
The man page should detail what the daemon does, even though in this
case it would've been nice to have the FreeBSD behahvior for -v.

5aa7372f4c Fix #19: Prefer /dev/kmsg over /proc/kmsg on Linux
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:

08b6c6fd0f man: Sync FreeBSD syslog.conf.5 man page w/ limitations in sysklogd
The FreeBSD syslogd has more priority matching features and can also

not yet support this, so that is removed and instead the syntax and

6bb6672ebf Remove klogd from the sysklogd project

project, klogd.  Now that syslogd performs logging of kernel messages

05f14d8366 Massive cleanup and simplification of syslogd man page
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.

4ee6211277 syslogd: Refactor internals to use new socket API
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.
