Backup compat tests use 'test-' prefix (as it was initially for all the
tests. Since changing this right not may break those backups in
non-trivial way, simply add cleanup for 'test-*' VMs.
When calling _register_watches() multiple times for dom0 (by passing
None or since 7e9c816b by passing the corresponding libvirt domain) the
check was missing if there is already a QubesDB in _qdb. Therefore a new
QubesDB was created and the old one is destroyed by the GC. As a
consequence the watch_fd is closed but the libvirt event handle for this
fd is still registered. So when libvirt calls poll() it returns
immediately POLLNVAL with the closed fd. This is not caught in libvirt
and the callback is called as if an event happened. _qdb_handler() now
calls read_watch() on the new fd for dom0 and thereby hangs the thread.
This leads (at leads) to qubes-manager to miss VM status updates and
block device events.

- for netvm it doesn't make sense, but instead of removing it (which
surely will break some code), make it always False
- when settings VM connections, uses_default_netvm is already loaded
- handle it properly during backup restore (really use default netvm,
istead of assuming it's the same as during backup)
Many drivers, including iwlwifi doesn't handle this well, resulting in
oopses etc. Also we're disabling PCI hotplug, which may be result in
more troubles here.
This reverts commit 2658c9a6e6.
QubesOS/qubes-issues#1673
Libvirt reports dom0 as "Domain-0". Which is incompatible with how Qubes
and libxl toolstack names it ("dom0"). So handle this as a special case.
Otherwise reconnection retries leaks event object every iteration.

Thanks @alex-mazzariol for help with debugging!
* qubesos/pr/34:
qfile-daemon-dvm: Implement LAUNCH and FINISH actions
qfile-daemon-dvm: Call static method by class name
qfile-daemon-dvm: Move dispVM killing into cleanup function
* qubesos/pr/33:
And some more quoting to satisfy #1672
Quoting all `cat`s as proposed in #1672
Modifying support cpio as proposed in #1672
Quoting the destination as proposed in #1672
If the action is LAUNCH instead of qubes.SomeService, then just start
the dispVM, write (only) its name to stdout, and quit.
If the action is FINISH, then kill and remove the named dispVM.
sfdisk options and input format differs between versions (dropped MB
units support), so instead of supporting all the combinations,
simply paste its result verbatim.
