* lvm-snapshots:
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

- no-else-return
- useless-object-inheritance
- useless-return
- consider-using-set-comprehension
- consider-using-in
- logging-not-lazy
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.
is_outdated() may be not supported by given volume pool driver. In that
case skip is_outdated information, instead of crashing the call.

* storage-properties:
storage: use None for size/usage properties if unknown
tests: call search_pool_containing_dir with various dirs and pools
storage: make DirectoryThinPool helper less verbose, add sudo
api/admin: add 'included_in' to admin.pool.Info call
storage: add Pool.included_in() method for checking nested pools
storage: move and generalize RootThinPool helper class
storage/kernels: refuse changes to 'rw' and 'revisions_to_keep'
api/admin: implement admin.vm.volume.Set.rw method
api/admin: include 'revisions_to_keep' and 'is_outdated' in volume info
Since Volume.is_outdated() is a method, not a property, add a function
for handling serialization. And at the same time, fix None serialization
(applicable to 'source' property).

Using '$' is easy to misuse in shell scripts, shell commands etc. After
all this years, lets abandon this dangerous character and move to
something safer: '@'. The choice was made after reviewing specifications
of various shells on different operating systems and this is the
character that have no special meaning in none of them.
To preserve compatibility, automatically translate '$' to '@' when
loading policy files.
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.
Allow using default feature value from netvm, not template. This makes
sense for network-related features like using tor, supporting ipv6 etc.
Similarly to check_with_template, expose it also on Admin API.
This one pool/volume property makes sense to change dynamically. There
may be more such properties, but lets be on the safe side and take
whitelist approach - allow only selected (just one for now), instead of
blacklisting any harmful ones.

Expired rules are skipped while loading the firewall. Do that also when
such rules expired after loading the firewall. This applies to both
Admin API and actually applying the rules (sending them to appropriate
VM).
Related QubesOS/qubes-issues#3020
Add public Admin API call to create Disposable VM that would be
automatically destroyed after shutdown. Do not keep this functionality
for qrexec-policy tool only.
Also, use admin.vm.Start there, instead of internal.vm.Start and
admin.vm.Kill instead of internal.vm.CleanupDispVM (this is enough,
because DispVM now have auto_cleanup property).

* qdb-watch:
tests: add qdb_watch test
ext/block: make use of QubesDB watch
vm: add API for watching changes in QubesDB
vm: optimize imports
api/admin: don't send internal events in admin.Events
Add explanation why admin.vm.volume.Import is a custom script
Follow change of qubesdb path return type
Rename vm.qdb to vm.untrusted_qdb
Some events are internal for a sole purpose of getting some data from
extension. Since listeners of admin.Events cannot return anything, there
is no sense in sending those events there.
This will allow starting processes and calling RPC services in those
events. This if required for usb devices, which are attached using RPC
services.
Intentionally keep device listing events synchronous only - to
discourage putting long-running actions there.
This change also require some not-async attach method version for
loading devices from qubes.xml - have `load_persistent` for this.
The first operation returns a token, which can be passed to the second
one to actually perform clone operation. This way the caller needs have
power over both source and destination VMs (or at least appropriate
volumes), so it's easier to enforce appropriate qrexec policy.
The pending tokens are stored on Qubes() instance (as QubesAdminAPI is
not persistent). It is design choice to keep them in RAM only - those
are one time use and this way restarting qubesd is a simple way to
invalidate all of them. Otherwise we'd need some additional calls like
CloneCancel or such.

In the end firewall is implemented as .Get and .Set rules, with policy
statically set to 'drop'. This way allow atomic firewall updates.
Since we already have appropriate firewall format handling in
qubes.firewall module - reuse it from there, but adjust the code to be
prepared for potentially malicious input. And also mark such variables
with untrusted_ prefix.
There is also third method: .Reload - which cause firewall reload
without making any change.
