7707715c78 man: update '-b' option description to match '-a' and usage text
The usage text (syslogd -?) and the syslogd.8 man page was not in sync
wrt. the -b option.  This patch updates it to match the layout of -a,
the -a option is also slightly updated.

29e932008d Fix #48: add option ('-K') to disable kernel logging
This patch adds support for disabling kernel logging, opensys().  This
is in addition to the character device validation check, and primarily
for use in container use-cases -- where logging kernel is not needed.

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:

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.

- Rip out old funix[] and finet support
- Add new concept of peers
- Linked list of peers can be > 20
- Temporarily open up to accept all remote conns
- Remove old logerror(), replaced with new log macros
