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.

...when verifying old backup restored. It wasn't present in the backup,
but its presence is expected in some cases. Properly setting 'servicevm'
feature is tested elsewhere.
Remove intermediate qubesd-query-fast proxy process.
This requires changing socket protocol to match what qrexec is sending
in the header.
