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.

cf9d281e5b syslogd: Adopt FreeBSD -F instead of -n to run in foreground
This change will probably break most installations.  We do this to free
up '-n' for use as disabling DNS lookups, from FreeBSD *and* NetBSD.

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

ff4f2cdb31 Replace homegrown PID file functions with std BSD pidfile()

- Rip out -i and -I from klogd, uses old PID file functions, and
  they're only kill(1) wrappers anyway

1a09654e79 Add logger tool from Finit project to complement sysklogd
This patch introduces a relicensed logit from the Finit[1] project.  It
has been rebranded as logger to complement the features implemented in
the sysklogd project.

Note, logger conflicts with the tool of the same name from util-linux.
