hmm ok it was doing something strange I remember, but what I dont :)   I
think it was that a sigpipe was generated on every syslog call because
syslog closed the fd after every call.  but I could be wrong.

I've been thinking about how to configure this.  Runtime configurable is
more desireable then compile time...  Perhaps we should do the
merge network.conf parsing into /etc/ais/openais.conf
merge log configuration parsing into /etc/ais/openais.conf
(we could even merge authkey into openais.conf)

Then openais.conf would look like:
# network configuration
network {

# logging configuration
log {
	type:file (or syslog or stderr)
	timestamp:yes (or no)

authkey {
key data

Any other bells that are needed?  This will help us prepare for the more
enhanced logging of gmi so we can knock out the remaining gmi bugs.

I'd also like to make log_printf take a parameter which is the service
that is logging.  ie:

log_printf (LOG_LEVEL_SECURITY|LOG_SERVICE_AMF, "some text");

and out comes:
date/time: SECURITY: AMF: some text

The name of the service allows easy filtering of the log for service
specific states.

After we do this we should consider instrumenting every api call to give
more information to the logging as to what openais is doing during
