It may happen (especially when VM doesn't close cleanly and needs to be
killed) that qubesdb-daemon will not notice VM shutdown immediately.
Normally it would stop after 60s timeout, but speed it up in case of
system shutdown
QubesOS/qubes-issues#1425
This is workaround for missing libxl/libvirt functionality: QubesOS/qubes-issues#1426
Also it should improve system shutdown time, as this is the situation
where all the VMs are shutting down simultaneously.

'xdotool search --sync' sometimes fails when searching for window. Fix
that by ensuring the windows is already visible when trying to enter
keys there.
Forgetting this leads to misterious errors (VM started with different
kernel than it was just set), so simplify the API.

When using PVGrub it doesn't make sense to attach modules.img, since
modules are already in the VM. Initramfs there will already handle such
situation and will not try to mount it, when VM's root filesystem
already contains appropriate /lib/modules/`uname -r`.
On the other hand, error earlier when initramfs is missing. While also
not used by PV Grub, the file is always specified in libvirt config and
when missing libvirt will throw rather cryptic error message.

1. Do not start GUI session - to reduce startup time
2. Use user="root" instead of sudo - not all templates have sudo
installed (for example fedora-21-minimal)
3. Add missing wait=True - otherwise VM may be shutdown during the
operation.

For a long time Qubes backup did not include symlinked files, which
apparently is quite common practice for users with multiple disks (for
example HDD + SSD). It is covered in documentation
(https://www.qubes-os.org/doc/secondary-storage/), but better solution
would be to simply include symlinked files.
Restore of such files would (of course) not preserve the symlinks -
normal files will be restored instead. But that's fine. If the user want
to move the data to another location, he/she can do that and restore the
symlink.
The only possible breakage from this change is having a copy (instead of
symlink) to a VM icon. But storing that symlink in a backup was broken
for some time (because of --xform usage) and it is handled during
restore, so not a real problem.
This doesn't cover all the problems with symlinked VM images - the other
one is qvm-block behaviour, which would treat such images as non-system
disks, so easily detachable (which would break VM operation). But that's
another story.
FixesQubesOS/qubes-issues#1384
In most cases it would be some leftover after failed restore, or even
the reason why the user is restoring a VM in the first place. Move it to
nearby directory, but do not remove - backup tool should _never_ remove
any data.
When the pre-existing directory would not be moved, restore utility
(`shutil.move`) would place the data inside of that directory, with
additional directory level (for example `/var/lib/qubes/appvms/work/work`),
which would be wrong and would later fail on `vm.verify_files`. And more
importantly - such VM would not work.
FixesQubesOS/qubes-issues#1386
Registering event implementation in libvirt and then not calling it is
harmful, because libvirt expects it working. Known drawbacks:
- keep-alives are advertised as supported but not really sent (cause
dropping connections)
- connections are not closed (sockets remains open, effectively leaking
file descriptors)
So call libvirt.virEventRegisterDefaultImpl only when it will be really
used (libvirt.virEventRunDefaultImpl called), which means calling it in
QubesWatch. Registering events implementation have effect only on new
libvirt connections, so start a new one for QubesWatch.

There are some circular dependencies (TemplateVM.appvms,
NetVM.connected_vms, and probably more), which prevents garbage
collector from cleaning them.
FixesQubesOS/qubes-issues#1380
The only directory to cleanup is cls.tmpdir. So make it simple, without
class property cleanup_paths, which for some reason didn't wasn't
emptied in tearDownClass.
This process may be running as root in case of default NetVM. But do not
kill it forcibly (through sudo or so), because it may also be stale
pid file. After all, QubesDB should automatically terminate when its VM
is terminated, so this code is already some error handling.

Don't send screen layout to the VM if we haven't received it from xrandr because this breaks proper initial screen layout set by gui-agent FixesQubesOS/qubes-issues#1305QubesOS/qubes-issues#998
If /etc/localtime in dom0 is a hardlink to zoneinfo file (instead of
symlink) and more than one zoneinfo file is hardlinked to this inode,
appVMs will get invalid timezone, e.g. "Europe/Warsaw\x0aPoland".
