This disables the "unauthenticated remote disk-filling service" by
default. A user can easily change this to 0 (or 2) to allow other
systems to log to their syslogd.

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 is redundant and causes message truncation. The <PRI> field is
skipped within wallmsg() itself.

Many projects use sysklogd with the shipped syslog.conf as their own
default /etc/syslog.conf. This is fine of course, but for many small
embedded systems getting all debug messages in the log by default is not
desirable.
This change drops debug messages from /var/log/syslog by default and
recommends admins to use /var/log/debug, or drop the debug filter.

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().

This patch refactors the way the primary and secondary syslogd is
started by the test framework. The generalizations not only make the
code more readable, it hopefully also makes it easier to add new tests
in the future.

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.

Since we currently cannot test kernel logging, and we don't want to risk
any log messages from the kernel to suddenly pop up and disturb tests,
this patch explicitly disables it.

This patch adds a very rudimentary container check. When one, of a
select few containers, are detected, sysklogd disables the kernel
logging -- since there's no point in logging kernel messages other
than from the host system.

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.

Issue #48 describes a problem with 100% CPU load in a container
use-case. Turns out one of the issues was that /dev/kmsg was
not a proper character device. This patch adds a very basic
check to ensure /dev/kmsg is usable.

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