ac8b8ebf0d klogd.8: Remove wording on role and superiority over syslogd
For most use-cases a kernel with CONFIG_KALLSYMS and a stand-alone
syslogd is sufficient.  No need for the complexity of klogd.

54edca09d9 syslogd: Close open UNIX and inet sockets on SIGTERM
When creating Inet sockets we may get multiple struct addrinfo records.
With this patch we support up to 16 records per Internet peer.  When
closing we iterate over all peers and all records.

Refactor socket_close() to clean up any lingering socket path when
closing UNIX socket.

0f0f8f845d syslogd: Add FreeBSD and NetBSD -n flag to disable DNS query
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.

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.

3b6199aaef Drop --with-syslogd-pidfile from configure, use -P option to syslogd
This patch drops the configure flag --with-syslogd-pidfile=foo since
syslogd now natively supports custom PID file using -P foo.

Also, the default PID file and syslog.conf paths have been changed from
the hard-coded /var/run (_PATH_VARRUN) and /etc to use configure paths.
This may not be appreciated by everyone but allows the project to have
support for all use-cases in a de facto standard fashion.

353cd10a06 Refactor, graft in FreeBSD fprintlog_first() & fprintlog_successive()
This patch looks big, but it's really just fprintlog() being split up
into three new functions: fprintlog_first() & fprintlog_successive() and
fprintlog_write().  Similar to how the FreeBSD syslogd is structured.

In the refactoring process Joey's proxy-prevention was removed.
