This is core part of migration. Things not migrated yet:
- DispVM (qubes_restore needs to be almost rewritten)
- VM xen config files should be fixed (use "script:" prefix in block device description, perhaps generate this files on VM start)

Get rid of dnsmasq in netvm.
...
qubes_setup_dnat_to_ns script sets up DNAT rules for DNS traffic; it is
triggered by dhclient or NetworkManager, and manually (in case there is
a static resolv.conf).
Put IP-dependent rules in qubes-core, after local ip is known. It could be
further improved by introducing custom chains, to enable iptables save.
Restrict FORWARD.

Reload Xend session params when we got an XenAPI.Failure exception
...
Because we're caching e.g. uuid and metrics objects for the Xend session, we can get an exception
when the VM changed the power state between since we cached the object. We now catch this exception
and reload uuid and metrics object in the handler.

Optimize Xend acesseses

Open Xend session only once, cache various intermediary Xen API
objects for faster access. This all is important for Qubes Manager, so that it
doesn'tintroduce too much load on Dom0's CPU when displaying the load chart.
