Multiple properties are related to system installed inside the VM, so it
makes sense to have them the same for all the VMs based on the same
template. Modify default value getter to first try get the value from a
template (if any) and only if it fails, fallback to original default
value.
This change is made to those properties:
- default_user (it was already this way)
- kernel
- kernelopts
- maxmem
- memory
- qrexec_timeout
- vcpus
- virt_mode
This is especially useful for manually installed templates (like
Windows).

Handle 'os' feature - if it's Windows, then set rpc-clipboard feature.
Handle 'gui-emulated' feature - request for specifically stubdomain GUI.
With 'gui' feature it is only possible to enable gui-agent based on, or
disable GUI completely.
Handle 'default-user' - verify it for weird characters and set
'default_user' property (if wasn't already set).

tests: fix handling app.pools iteration
storage/lvm: add repr(ThinPool) for more meaningful test reports
tests: adjust for variable volume path
api/admin: expose volume path in admin.vm.volume.Info
tests: LVM: import, list_volumes, volatile volume, snapshot volume
tests: collect all SIGCHLD before cleaning event loop
storage/lvm: use temporary volume for data import
tests: ThinVolume.revert()
tests: LVM volume naming migration, and new naming in general
storage/lvm: improve handling interrupted commit

Ignore:
- not-an-iterable - false possitives for asyncio coroutines
Ignore all the above in qubespolicy/__init__.py, as the file will be
moved to separate repository (core-qrexec) - it already has a copy
there, don't desynchronize them.
Since (for LVM at least) path is dynamic now, add information about it
to volume info. This is not very useful outside of dom0, but in dom0 it
can be very useful for various scripts.
This will disclose current volume revision id, but it is already
possible to deduce it from snapshots list.
Do not write directly to main volume, instead create temporary volume
and only commit it to the main one when operation is finished. This
solve multiple problems:
- import operation can be aborted, without data loss
- importing new data over existing volume will not leave traces of
previous content - especially when importing smaller volume to bigger
one
- import operation can be reverted - it create separate revision,
similar to start/stop
- easier to prevent qube from starting during import operation
- template still can be used when importing new version

First rename volume to backup revision, regardless of revisions_to_keep,
then rename -snap to current volume. And only then remove backup
revision (if exceed revisions_to_keep). This way even if commit
operation is interrupted, there is still a volume with the data.
This requires also adjusting few functions to actually fallback to most
recent backup revision if the current volume isn't found - create
_vid_current property for this purpose.
Also, use -snap volume for clone operation and commit it normally later.
This makes it safer to interrupt or even revert.

qvm-clock-sync fails with a python subprocess error on line 43 when the `date ... -s ...` fails due to insufficient privileges to set the date. This commit checks to see if the program has effective UID root before attempting to set the date.
is_outdated() may be not supported by given volume pool driver. In that
case skip is_outdated information, instead of crashing the call.

* qubesos/pr/210:
spec.in: remove useless condition on Fedora 17 which induces problem with Travis
spec.in: add changelog placeholder
Define backend_vmm macro
doc: handle release definition when not being in a git repository
Remove _builddir
Create .spec.in and Source0
Before waiting for remaining tasks on event loop (including libvirt
events), make sure all destroyed objects are really destroyed. This is
especially important for libvirt connections, which gets cleaned up only
when appropriate destructor (__del__) register a cleanup callback and it
gets called by the loop.
Use VM's actual IP address as a gateway for other VMs, instead of
hardcoded link-local address. This is important for sys-net generated
ICMP diagnostics packets - those must _not_ have link-local source
address, otherwise wouldn't be properly forwarded back to the right VM.
If domain die when trying to kill it, qubesd may loose a race and try to
kill it anyway. Handle libvirt exception in that case and conver it to
QubesVMNotStartedError - as it would be if qubesd would win the race.

Scripts do parse its output sometimes (especially `lvs`), so make sure
we always gets the same format, regardless of the environment. Including
decimal separator.
FixesQubesOS/qubes-issues#3753
Don't rely on timestamps to sort revisions - the clock can go backwards
due to time sync. Instead, use a monotonically increasing natural number
as the revision ID.
Old revision example: private.img@2018-01-02-03T04:05:06Z (ignored now)
New revision example: private.img.123@2018-01-02-03T04:05:06Z
* devel-storage-fixes:
storage/file: use proper exception instead of assert
storage/file: import data into temporary volume
storage/lvm: check for LVM LV existence and type when creating ThinPool
storage/lvm: fix size reporting just after creating LV
Similar to LVM changes, this fixes/improves multiple things:
- no old data visible in the volume
- failed import do not leave broken volume
- parially imported data not visible to running VM
