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.

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

9aaa7ec8c4 syslogd: Install SIGHUP handler earlier
When a heavily loaded system starts up syslogd may not in time reach its
original installation of the SIGHUP handler before receiving the signal.
It will then die and have to be restarted by PID 1.

This patch installs the SIGHUP handler early, with all the other signals
right after command line parsing.
