Log to a temporary file if permission is denied to log to /var/log/xend.log,

Remove all the log-related garbage from XendRoot -- just about every module

XendRoot replicate this functionality.
Remove XendRoot.event_handler, which hasn't been in use since the EventServer

tools. /dev/xen/evtchn is now used by daemons to connect to
remote domains: the advantage is that the local ports are garbage
collected automatically if the daemon dies. xen no longer
constructs end-to-end event-channel port pairs -- it allocates an
unbound port in new domU and writes that port to xenstore. It is
then picked up by teh appropriate daemon which does interdomain bind
via /dev/xen/evtchn.

that caused bug #278.
Move the state_set(TERMINATED) call onto the end of cleanupDomain rather than
destroyDomain, so that this flag is set when XendDomain cleans up a domain
that was killed without going through Xend.
Remove is_terminated, as this check is no longer necessary, since we are using
Zombie prefixes instead.

#280. The cpu/<id>/availability paths had moved into /vm, but that is not
easily accessible by the hotplugging driver, so I have created a /vm entry
called vcpu_avail, so that the setting migrates along with the domain, and
moved the cpu/<id> ones back to /local/domain.
Don't try and destroy the domain twice if it fails within construct. This
wasn't harming anything, but there's no need.
