The user of ExtraTestCase don't need to know anything about asyncio.
vm.run().wait() normally is a coroutine, but provide a wrapper that
handle asyncio.
This fixes FD leak in input proxy tests.
Since 4dc86310 "Use maxmem=0 to disable qmemman, add more automation to
it" meminfo-writer service is not accessible directly. maxmem property
is used to encode memory management instead.
- Two new methods: .features.check_with_adminvm() and
.check_with_template_and_adminvm(). Common code refactored.
- Two new AdminAPI calls to take advantage of the methods:
- admin.vm.feature.CheckWithAdminVM
- admin.vm.feature.CheckWithTemplateAndAdminVM
- Features manager moved to separate module in anticipation of features
on app object in R5.0. The attribute Features.vm renamed to
Features.subject.
- Documentation, tests.

vm/dispvm: fix /qubes-vm-presistence qubesdb entry
vm/mix/net: prevent setting provides_network=false if qube is still used
tests: updates-available notification
tests/network: reduce code duplication
tests: listen on 'misc' socket too
First install test-pkg-1.0, then add test-pkg-1.1 to repo and check if
updates-available flag is set. Then install updates and check if the
flag is cleared.

The new property is meant for management stack (Salt) to set which DVM
template should be used to maintain given VM. Since the DispVM based on
it will be given ultimate control over target VM (qubes.VMShell
service), it should be trusted. The one pointed to by default_dispvm
not necessary is one.
The property defaults to the value from the template (if any), and then
to a global management_dispvm property. By default it is set to None.

Migrate meminfo-writer=False service setting to maxmem=0 as a method to
disable dynamic memory management. Remove the service from vm.features
dict in the process.
Additionally, translate any attempt to set the service.meminfo-writer
feature to either setting maxmem=0 or resetting it to the default (which
is memory balancing enabled if supported by given domain). This is to at
least partially not break existing tools using service.meminfo-writer as
a way to control dynamic memory management. This code does _not_ support
reading service.meminfo-writer feature state to get the current state of
dynamic memory management, as it would require synchronizing with all
the factors affecting its value. One of main reasons for migrating to
maxmem=0 approach is to avoid the need of such synchronization.
QubesOS/qubes-issues#4480
Use maxmem=0 for disabling dynamic memory balance, instead of cryptic
service.meminfo-writer feature. Under the hood, meminfo-writer service
is also set based on maxmem property (directly in qubesdb, not
vm.features dict).
Having this as a property (not "feature"), allow to have sensible
handling of default value. Specifically, disable it automatically if
otherwise it would crash a VM. This is the case for:
- domain with PCI devices (PoD is not supported by Xen then)
- domain without balloon driver and/or meminfo-writer service
The check for the latter is heuristic (assume presence of 'qrexec' also
can indicate balloon driver support), but it is true for currently
supported systems.
This also allows more reliable control of libvirt config: do not set
memory != maxmem, unless qmemman is enabled.
memory != maxmem only makes sense if qmemman for given domain is
enabled. Besides wasting some domain resources for extra page tables
etc, for HVM domains this is harmful, because maxmem-memory difference
is made of Popupate-on-Demand pool, which - when depleted - will kill
the domain. This means domain without balloon driver will die as soon
as will try to use more than initial memory - but without balloon driver
it sees maxmem memory and doesn't know about the lower limit.

It makes a lot of sense to call long-running operations in that event
handler, including calling back into the VM. Allow that by using
fire_event_async, not just fire_event.
Also, document the event.
Commit 15cf593bc5 "tests/lvm: fix checking
lvm pool existence" attempted to fix handling '-' in pool name by using
/dev/VG/LV symlink. But those are not created for thin pools. Change
back to /dev/mapper, but include '-' mangling.

Restore old code for calculating subdir within the archive. The new one
had two problems:
- set '/' for empty input subdir - which caused qubes.xml.000 to be
named '/qubes.xml.000' (and then converted to '../../qubes.xml.000');
among other things, this results in the wrong path used for encryption
passphrase
- resolved symlinks, which breaks calculating path for any symlinks
within VM's directory (symlinks there should be treated as normal files
to be sure that actual content is included in the backup)
This partially reverts 4e49b951ce.

vm.kill() will try to get vm.startup_lock, so it can't be called while
holding it already.
Fix this by extracting vm._kill_locked(), which expect the lock to be
already taken by the caller.
