Move parsing of incoming syslog messages to their own section.
This should make it more manageable.

No functional change intended, debugging output slightly changed.

Start to replace the home grown syslogd(8) internal debug and logging
functions with a more common log.c implementation. Of course
openlog(3) cannot be used, so adapt the log.[ch] initially copied
from ospfd(8) to syslogd's special needs. As the messages are
limited to ERRBUFSIZE anyway, malloc(3) in the error logging code
can be avoided. Changing all log calls to the new API will be done
in a separate step.

Implement sending syslog messages over TLS.

Switch syslogd from using poll(2) to libevent.

Buffered logging for syslogd. Logs may be stored in memory buffers and
extracted using a small client. Useful for diskless systems.
much feedback from deraadt@, canacar@, jmc@, jakob@ ; ok deraadt@

Privilege separated syslog daemon. The child listening to log requests drops
to user _syslogd and chroots itself, while the privileged parent grants it
access to open logfiles and other calls it needs.

The only difference from existing behaviour is that if syslog.conf changes
and syslogd receives a HUP, it will re-exec itself and have two new PIDs.
A HUP with an unchanged config will make syslogd reopen logfiles as before.

Lots of help and code from deraadt@ , and advice from millert@

Various versions tested by todd, cloder, mpech, markus, tdeval and others
