Instead of running the domark() timer on half the MarkInterval option,
we take the FreeBSD approach and run on each TIMERINTVL (30 sec), same
as the doflush() timer. This allows greater resolution on the MARK log
message, meaning we would be off by < 30 seconds instead of the current
MarkInterval / 2.

This patch imports the FreeBSD meaning to the `-c` command line option.
It disables "last message repeated" style log compression for repeated
log messages. A single `-c` disables compression for pipes, another
`-c` (-cc works) also disables compression for all other log targets.

Logic for secure mode setting in .conf file
- Command line always wins
- SIGHUP activates changes
Note, if -s is given on command line it always wins, regardless.

This patch allows the user to disable the 8-bit data check in the log
message validator. If you have experienced problems with logging any
unicode (utf-8) messages after v1.6, this option is for you.
The correct way to handle this is to add proper parser support for the
Unicode BOM, defined in RFC5424[1], as NetBSD syslogd does[2], search
for IS_BOM().

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.

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.

We need the '-K' option to disable kernel logging, so this option needs
to be renamed, unfortunately. Fortunately it's not been released yet.

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.

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:

The FreeBSD syslogd has more priority matching features and can also
group rules per program/hostname logging. The sysklogd project does
not yet support this, so that is removed and instead the syntax and
examples are better described.

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.

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.

For most use-cases a kernel with CONFIG_KALLSYMS and a stand-alone
syslogd is sufficient. No need for the complexity of klogd.
