Until now the udev script for blktap devices needs to decide if to
signal success or failure to xend. As this script runs completely
independent of blktapctrl and tapdisk/ioemu which do the real work,
the udev script can't even theoretically know if tapdisk is happy.
This patch removes the udev script and replaces its checks by new
ones in libblktap.

This is a corrected version of a patch commited as c/s 19250 and
reverted by c/s 19314. Thanks to "trap sigerr ERR" in
xen-hotplug-common.sh the xen-hotplug-cleanup would exit when reading
/local/domain/ID/vm fails thus skipping all the xenstore-rm lines in
the rest of the script.
Change deviceDestroy behavior to remove /vm/UUID/device/...
path only when force was used (as it already does so for both frontend
and backend) and do the removing from xen-hotplug-cleanup script when
we are sure the device is really not attached to the guest any more.

Show errors in the way they are coming from xm command only (no usage
is printed now). Watchdog_wm() has been changed for not showing dots
in the process of shutting down domains and if an error occurs it
prints target domain, operation (save/restore/migrate etc.) and reason
of failure in more user-friendly way.
