audio: set sink volume to workaround alsa save/restore issue
audio: increase timeout to match hvm loading
audio: auxiliary pauses should be harmless now, place them back just in case
audio: add silence threshold
audio: unload guest' module-vchan-sink in hvm tests
audio: fix prepare_audio_vm
audio: do not use pacat on copying audio_in.raw
Audio: rework audio tests
Similart to property-reset:xid, emit property-reset:stubdom_xid when
domain is started/stopped. This allows client side of the Admin API
(qubes-core-admin-client) to invalidate the cache when necessary.
Found by audio tests: #352
Don't update _size in the getter, so it can be unlocked (which is
helpful for QubesOS/qubes-issues#5935).
!!! If cherry-picking for release4.0, also adjust import_data() to !!!
!!! use self.size (no underscore) instead of self._get_size() !!!
Fix load error reporting - make sure 'err' variable is transferred into
'runTest' function scope.
Then, relax test loading requirements - use 'resolve' instead of 'load',
to bypass dependencies check (defined in setup.py of the package). The
required dependencies should be handled by RPM already, and in some
cases may not match those in python package. An example is PDF
converter, where dependencies at python level are set for the actual
converter, which is irrelevant for running tests from dom0 (tests will
interact with PDF converter inside a VM).
Replace constant audio bytearray with generated sine wave sample
to get more robust results across test environments.
Use zero-crossings as an audio fingerprint
and compare it with sine wave frequency.
XSA-320 / CVE-2020-0543 affects Ivy Bridge and later platforms, but a
fix (microcode update) won't be available for Ivy Bridge. Disable
affected instruction (do not announce it in CPUID - complying software
should not use it then).
The revisions_to_keep should be inherited from the pool by default (or
whatever else logic is in the storage pool driver). When creating VM in
a specific pool, volumes config is re-initialized to include right
defaults. But the config cleaning logic in `_clean_volume_config()`
failed to remove revisions_to_keep property initialized by the default
pool driver. This prevented new pool driver to apply its own default
logic.
An extreme result was inability to create a VM in 'file' pool at all,
because it refuses any revisions_to_keep > 1, and the default LVM
pool has revisions_to_keep = 2.
Keep it at original files, to still load it using compat rules.
This way the update should not break user's policies.
Note the unchanged policy files are still going to be removed - meaning
those calls will use the new policy.

* origin/pr/344:
travis: pip -> pip3
Update .travis.yml
Drop initial root thin pool definition
Prevent double hyphens in thin_pool parsing
Rename default root thin pool from 'lvm' to 'root'
* rename-property-del-reset:
Fire property-reset event when default value might change
Convert handler to use property-reset instead of property-del
Remove leftovers of default_fw_netvm
Deprecate property-del:name events and introduce property-reset:name instead
Those are only some cases, the most obvious ones:
- defaults inherited from a template
- xid and start_time on domain start/stop
- IP related properties
- icon

There was also one case of triggering property-{del => reset}
synthetically on default value change. Adjust it too and drop -pre-
event call in that case.
QubesOS/qubes-issues#5834
And the same for -pre- events.
The property-del name is really confusing (it makes sense only for those
with deep knowledge of the implementation), because the property isn't
really deleted - it is only reverted to the "default" state (which most
properties have). So, name the event property-reset, intentionally
similar to property-set, as it is also kind of a value change.
Additionally the property-reset event is meant to be called when the
(dynamic) default value changes. Due to the current implementation, it
is a manual process so it can't be guaranteed to be called in all those
cases, but lets try to cover as much as possible.
