This all either have been migrated to core3, or is not needed anymore.
There is still qvm-tools directory with a few tools that needs to be
migrated, or installed as is.
This requires creating LVM volume group, so create on based on loop dev
in /tmp.
This is rather rough, but if any of this fails, run the tests anyway -
it will simply skip LVM tests.
Device ident may contain only characters allowed in qrexec argument.
This will allow using it directly in qrexec argument in Attach/Detach
methods.
This also means PCI extension will need to be updated (it uses ':' in
ident).

This is required to get shutdown notification, when it wasn't initiated
by qubesd (for example 'poweroff' command inside of VM).
Libvirt event loop implementation must be registered before making
connection to libvirt, so move it to the beginning of main().
For now, only 'domain-shutdown' event is emited.
User session may not be started at all (for example no qubes packages
installed there), so don't block it in all the cases. Also this would
prevent running 'qubes.WaitForSession' service...
In practice, default value for 'gui' argument is False, so in most cases
user session will be ignored. Which doesn't matter in most cases -
especially for services called by qubesd.
Keep it uniform - QubesVM() object is responsible for handling
vm.dir_path, Storage() is responsible for handling disk volumes (which
may live in that directory

Allow specific pool implementation to provide asynchronous
implementation. vm.storage.* methods will detect if given implementation
is synchronous or asynchronous and will act accordingly.
Then it's up to pool implementation how asynchronous should be achieved.
Do not force it using threads (`run_in_executor()`). But pool
implementation is free to use threads, if consider it safe in a
particular case.
This commit does not touch any pool implementation - all of them are
still synchronous.

Split actual filtering done by mgmt-permission: events into calling an
event and applying returned filters. This way filtering done in
mgmt.Events handler could reuse the same function.
...in core-mgmt-client repository. qubesd isn't the right place to start
GUI applications, which will be even more important when GUI domain will
be something different than Dom0.
QubesOS/qubes-issues#833
Some methods inherited from dict (pop and setdefault here) are covered
by placeholders raising NotImplementedError. Lets fix their signatures
(to match those of dict) to really get NotImplementedError, instead of
TypeError.
This allows avoid race condition between registering event handlers and
performing some action. The important thing is the event sent after
registering event handlers in qubesd. This means state changes (like
VM start/stop) after 'connection-established' event will be included in
event stream.

Management API gives access only to qubes.property. And this is
actually a good thing, so instead of extending it to access also
builtins.property, add a simple decorator to define read-only, stateless
qubes.property.
QubesOS/qubes-issues#2622
qvm-ls tool (as all other tools) will be accessing properties through
API, so no need (nor sense) for this tool-specific attributes in
qubes.property. The only somehow used was ls_width, and in fact it made
the output unnecessary wide.
The tool itself is already moved to core-mgmt-client repository.
QubesOS/qubes-issues#853
Standard methods return only one value, after operation is completed,
but events-related methods may return multiple values during the method
execution time. Provide a callback for such cases.
Also, according to specification, avoid sending both event and non-event
values.
QubesOS/qubes-issues#2622
Allow method handler to decide if operation could be cancelled. If yes,
when connection to the qubesd is terminated (and
protocol.connection_lost get called) the operation is cancelled using
standard asyncio method - in which case asyncio.CancelledError is thrown
inside method handler. This needs to be explicitly enabled, because
cancellable methods are much harder to write, to maintain consistent
system state.
Caveat: protocol.connection_lost is called only when trying to send some
data to it (and it's already terminated). Which makes this whole
mechanism useful only for events. Otherwise, when sending some data (and
possibly detecting that connection is broken), the operation is already
completed.
