missing import inside blkif. Fix the command parsing for op_device_destroy and
op_device_configure -- the device IDs should be strings, to allow the user to
specify devices by name as well as number.
This is the second half to the fixes for bug #315.

This fixes the Invalid token error that has been seen on xend restart.

because we are already inside the ValueError exception handler, so we know that
the give device identifier is not an integer, and DevController.destroyDevice
only accepts integers. Fixes bug #315.

the domain, to make it clear that it is a zombie, but this renaming cannot
check the uniqueness of the new name, because this causes a deadlock with
XendDomain. Instead, we allow the name to be non-unique for the case of
zombie domains.
Change the locking in waitForShutdown and state_set to be robust in the face of
exceptions.
Rename the STATE_VM_ constants to STATE_DOM_.

and xenconsole out of /usr/libexec/xen and into one of /usr/lib/xen/bin or
/usr/lib64/xen/bin. Remove all the PATH hacking inside Xend, and rely upon
the PATH being set correctly from outside. Added an auxbin module for
handling the hacky stuff.
Replace the few /usr/bin/python bang paths with /usr/bin/env python.

Log to a temporary file if permission is denied to log to /var/log/xend.log,
as happens when you are not root. Fixes bug #305.
Remove all the log-related garbage from XendRoot -- just about every module
was going straight to XendLogging.log already, so there was no need to have
XendRoot replicate this functionality.
Remove XendRoot.event_handler, which hasn't been in use since the EventServer
was removed.

Allow xm block-detach to take a device name as well as a device ID. This
closes bug #285 and fixes xm-test's 01_block-destroy_btblock_pos.py and

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.
