Force refreshing domain list after starting new VM, even if the
triggering watch wasn't about domain list change. Otherwise (with
outdated domain list) memory allocated to a new VM, but not yet used may
be redistributed (leaving to little to the Xen itself).
FixesQubesOS/qubes-issues#1389
Retrieve a domain list only after obtaining global lock. Otherwise an
outdated list may be used, when a domain was introduced in the meantime
(starting a new domain is done with global lock held), leading to #1389.

Test if DispVM firewall rules are:
- inherited from a calling VM
- saved properly (so will be effective after firewall reload)
- saved only for that DispVM (#1608)
QubesOS/qubes-issues#1608
It should be created at VM creation time (or template changes commit).
But for example for HVM templates created before implementing
QubesOS/qubes-issues#1573, there would be no such image. So create it
when needed, just before VM startup
FixesQubesOS/qubes-issues#1602
In this case, qmemman would not manage to get any memory state for such
VM, so memory_current would be 'None'. But later it would perform
arithmetics on it, which would result in qmemman crash (TypeError
exception).

Regression test for:
QubesOS/qubes-issues#1515
It assumes existing broken symlink in user dom0 home. Thanks for systemd
it is the case (`~/.local/share/systemd/user`).
We still can't support running HVM template and its VMs simultaneously
(easily), but still, have root-cow.img handled for HVM template, to
allow qvm-revert-template-changes.

When VM got some memory assigned, balloon driver may not pick it up
immediatelly and the memory will still be seen as "free" by Xen, but VM
can use (request) it at any time. Qmemman needs to take care of such
memory (exclude it from "free" pool), otherwise it would redistribute it
to other domains, allowing the original domain to drain Xen memory pool.
Do this by redefining DomainState.memory_actual - it is now amount of
memory available to the VM (currently used, or possibly used). Then
calculate free memory by subtracting memory allocated but not used
(memory_target-memory_current).

This is needed, because when tests fail to load, unittest module
generates artificial „LoadTestsFailure” class -- not based on our
QubesTestCase, so it does not have .log attribute.
This fixes up 75c3f355db "qubes/vm/qubesvm: fix domain's UUID management".
Previously 'domain-init' was never really fired.

In some (most) cases VM needs to be started to complete resize
operation. This may be unexpected, so make it clear and do not start the
VM when the user did not explicitly allow that.

When /var/lib/qubes/appvms is a mount point of ext4 filesystem, there
will be already 'lost+found' directory. Avoid this conflict.
