Even when volume is not persistent (like TemplateBasedVM:root), it
should be resizeable. Just the new size, similarly to the volume
content, will be reverted after qube shutdown.
Additionally, when VM is running, volume resize should affect _only_ its
temporary snapshot. This way resize can be properly reverted together
with actual volume changes (which include resize2fs call).

- catch both QubesException and libvirtError - do not kill starting VM
just because an error while connecting _other_ VMs to it
- try to detach network first (and do not abort on error) - if
libvirt/libxl will manage to cleanup stale interface this way, the
attach operation below may succeed.

1. Make sure VMs are started after dom0 actual memory usage is reported
to qmemman, otherwise dom0 will hold 4GB, even if just a little over 1GB
is needed at that time.
2. Request only vm.memory MB from qmemman, instead of vm.maxmem. While
HVM with PCI devices indeed do not support populate-on-demand, this is
already handled in libvirt XML.
The later may often cause VM startup fail on systems with 8GB of memory,
because maxmem is 4GB there and with dom0 keeping the other 4GB (see
point 1) there is not enough memory to start any sych VM.

* qubesos/pr/187:
Don't fail create/clone if /var/lib/qubes/TYPE/NAME/ exists
Make 'qvm-volume revert' really use the latest revision
Fix wrong mocks of Volume.revisions
* qubesos/pr/185:
vm: remove doc for non-existing event `monitor-layout-change`
vm: include tag/feature name in event name
events: add support for wildcard event handlers
admin.vm.volume.ListSnapshots returned volume revisions in undefined
order, but 'qvm-volume revert' assumes the list to be in chronological
order. Make that assumption true.
* devel-20180115:
tests: update PCI devices tests for core3 API
tests: make tests.extra.VMWrapper hashable
qmemman: do not close stdout/stderr in daemon mode
qmemman: fix early crash
qubesvm: do not try to define libvirt object in offline mode
tests: one more missing virt_mode=hvm
qubesvm: PVH minor improvements
tests: minor fixes
tests: add run_service and qrexec_policy wrappers to ExtraTestCase
tests: clear PCIDevice cache after each test
importing pkg_resources and looking up entry points wastes 100ms+
of time, which is totally unnecessary

clear_outdated_error_markers crashes if memory stats are not retrieved
yet. In practice it crashes at the very first call during daemon
startup, making the whole qmemman unusable.

qmemman: clear "not responding" flags when VM require more memory

- use capital letters in acronyms in documentation to match upstream
documentation.
- refuse to start a PVH with without kernel set - provide meaningful

Hint shellcheck where to look for sourced files, if in repository
This will ease running shellcheck from the repository.
