qubes.NotifyTools: ignore '/qubes-tools/version' completely
It isn't used for anything, so simply ignore it for good.

vm: init vm.storage and vm.volumes in BaseVM
This way also AdminVM will have (empty) properties there. It is much
cleaner than adding `if hasattr` or catching AttributeError everywhere.

vm: improve sending events for tags and features

api/misc: integrate qubes.NotifyTools logic with qubes.FeaturesRequest
Make qubes.NotifyTools reuse logic of qubes.FeaturesRequest, then move
actual request processing to 'features-request' event handler. At the
same time implement handling 'qrexec' and 'gui' features request -
allowing to set template features when wasn't already there.
Behavior change: template is no longer allowed to change feature value
(regardless of being True or False). This means the user will always be
able to override what template have set.

devices: drop 'data' and 'frontend_domain' fields, rename 'devclass' to 'bus'
Drop DeviceInfo.data - device extension should provide a subclass with
proper individual fields.
Drop DeviceAssignment.frontend_domain - this information is redundant -
frontend domain is defined by where DeviceAssignment is attached.
Rename DeviceCollection.devclass to bus - devclass if confusing here,
because this term is also used for DeviceInfo subclass.

storage: use direct object references, not only identifiers
Reference objects, not their IDs - this way when object is modified, it
is visible everywhere where it is used. Main changes:
- volume.pool - Pool object
- volume.source - Volume object

Since volume have Pool object reference now, move volume related
functions into Volume class (from Pool class). This avoids horrible
`storage.get_pool(volume).something(volume)` construct.

One issue here is since volume.source reference a Volume object from a
different VM - VM's template, now VM load order is important. Since we
don't have control over it, initialize vm.storage when needed - possibly
while initializing storage of different VM. Since we don't have cycles
in AppVM-TemplateVM dependencies, it is safe.

Also, since this commit, volume.source (if defined) always points at
volume of the same name from VM's template. Using volumes with something
else as a source is no longer supported.

vm: fix volume_config
- kernel volume shouldn't have snap_on_start, it's read-only volume
  anyway
- root volume of AppVM should have placeholder for 'source'
- private volume of AppVM should _not_ have placeholder for 'source'
(it's ignored anyway, because snap_on_start=False)

vm/mix/net: remove cleanup_vifs
With libvirt in place, this isn't enough - libvirt also keep VM
configuration in its memory and adjusting xenstore doesn't change that.
In fact changing xenstore behind it back make it even worse in some
situations.

vm: adjust VM's root volume when changing its template
Re-init volume config of all 'snap_on_start' volumes at template
chanage. For this, save original volume config and re-use
config_volume_from_source function introduced in previous commit.

At the same time, forbid changing template of running AppVM or any
DispVM.

vm: change kernel=None to kernel=''
vm.kernel property have type 'str'. Putting None there makes a lot of
troubles: it gets encoded as 'None' in qubes.xml and then loaded back as
'None' string, not None value. Also it isn't possible to assign None
value to str property throgh Admin API.

kernel='' is equally good to specify "no kernel from dom0".

vm: avoid starting the same VM multiple times simultaneously
While libvirt handle locking itself, there is also Qubes-specific
startup part. Especially starting qrexec-daemon and waiting until
qrexec-agent connect to it. When someone will attempt to start VM the
second time (or simply assume it's already running) - qrexec will not be
connected yet and the operation will fail. Solve the problem by wrapping
the whole vm.start() function with a lock, including a check if VM is
running and waiting for qrexec.

Also, do not throw exception if VM is already running.

This way, after a call to vm.start(), VM will be started with qrexec
connected - regardless of who really started it.
Note that, it will not solve the situation when someone check if VM is
running manually, like:

    if not vm.is_running():
        yield from vm.start()

Such code should be changed to simply:

    yield from vm.start()
