* The --log command line argument takes one of 4 values
- none - no logging (the default)
- hv - log all hypervisor messages
- guest - log all guest messages
- both - log all guest & hypervisor messages
* The --log-dir command line argument takes a path to specify where
to store logfiles. If omitted it defaults to /var/log/xen/console
* The hypervisor logfile is $LOGDIR/hypervisor.log
* The guest logfile is $LOGDIR/guest-[NAME].log
* If receiving a SIGHUP it will close & re-open all log files to
enable logrotate to do its magic
* Fixes the permissions of /var/run/xenconsoled.pid
* Adds a --pid-file command line argument to override the default
location of pid file (this is not really related to logging, but
since I was in that code...)
