vm: include tag/feature name in event name
Rename events:
 - domain-feature-set -> domain-feature-set:feature
 - domain-feature-delete -> domain-feature-delete:feature
 - domain-tag-add -> domain-tag-add:tag
 - domain-tag-delete -> domain-tag-delete:tag

Make it consistent with property-* events. It makes more sense to
include tag/feature name in event name, so handler can watch a single
tag/feature - which is the most common case. Otherwise, most handlers
would begin with `if feature == '...'` anyway, wasting time on most
events.

In cases where multiple features/tags should be handled by a single
handler, it is now possible to register a handler with wildcard, for
example `domain-feature-set:*`.

events: add support for wildcard event handlers
Support registering handlers for more flexible wildcard events: not only
'*', but also 'something*'. This allows to register handlers for
'property-set:*' and such.

Use default_dispvm (not default_template) for new DispVM
When creating a new VM of type DispVM without specifying any template
(e.g. "qvm-create --class DispVM --label red foo"), use default_dispvm.
Otherwise it would fail saying "Got empty response from qubesd."

tests: resurrect extra tests loader
Load integration tests from outside of core-admin repository, through
entry points.
Create wrapper for VM object to keep very basic compatibility with tests
written for core2. This means if test use only basic functionality
(vm.start(), vm.run()), the same test will work for both core2 and
core3. This is especially important for app-* repositories, where the
same version serves multiple Qubes branches.
This also hides asyncio usage from tests writer.

See QubesOS/qubes-issues#1800 for details on original feature.

Fix starting VM with kernel=None
When dom0 do not provide the kernel, it should also not set kernel
command line in libvirt config. Otherwise qemu in stubdom fails to start
because it get -append option without -kernel, which is illegal

Add IPv6 related VM properties
Add property for IPv6 address ('ip6'). Build default value similarly to
IPv4 - common prefix + QID or Disp ID (for DispVMs).
This all is disabled unless 'ipv6' feature is enabled. It is inherited
from netvm (not template).
Even when enabled, VM may decide to not use it - or simply not support
it.

app: kill default_fw_netvm property
Having both default_netvm and default_fw_netvm cause a lot of confusion,
because it isn't clear for the user which one is used when. Additionally
changing provides_network property may also change netvm property, which
may be unintended effect. This as a whole make it hard to:
- cover all netvm-changing actions with policy for Admin API
- cover all netvm-changing events (for example to apply the change to
the running VM, or to check for netvm loops)

As suggested by @qubesuser, kill the default_fw_netvm property and
simplify the logic around it.
Since we're past rc1, implement also migration logic. And add tests for
said migration.

Improve checking for netvm loop
There were many cases were the check was missing:
 - changing default_netvm
 - resetting netvm to default value
 - loading already broken qubes.xml

Since it was possible to create broken qubes.xml using legal calls, do
not reject loading such file, instead break the loop(s) by setting netvm
to None when loop is detected. This will be also useful if still not all
places are covered...

Place the check in default_netvm setter. Skip it during qubes.xml loading
(when events_enabled=False), but still keep it in setter, to _validate_ the
value before any property-* event got fired.

qubesvm: make initial qmemman request consistent with libvirt config
If HVM have PCI device, it can't use PoD, so need 'maxmem' memory to be
started. Request that much from qmemman.
Note that is is somehow independent of enabling or not dynamic memory
management for the VM (`service.meminfo-writer` feature). Even if VM
initially had assigned maxmem memory, it can be later ballooned down.

b907303a39 qubes/vm: Improve stopped event handling
The previous version did not ensure that the stopped/shutdown event was
handled before a new VM start. This can easily lead to problems like in
QubesOS/qubes-issues#3164.

This improved version now ensures that the stopped/shutdown events are
handled before a new VM start.

Additionally this version should be more robust against unreliable
events from libvirt. It handles missing, duplicated and delayed stopped
events.

Instead of one 'domain-shutdown' event there are now 'domain-stopped'
and 'domain-shutdown'. The later is generated after the former. This way
it's easy to run code after the VM is shutdown including the stop of
it's storage.

app: fix setting default_*netvm
1. Fire both property-pre-del:netvm and property-del:netvm - those
events should be fired in pairs - especially one may assume the other
will be called too. This is the case here - one disconnect old netvm,
the other connect the new one.

2. Remove spurious 'newvalue' argument for property-del:netvm event.

3. Fix logic for default_fw_netvm/default_netvm usage. The former is
used if vm.provides_network=True.

oldvalue should contain the old value, even if it was default one. Same

actual value is most useful.

devices: implement DeviceCollection.update_persistent()
Allow attached device to be converted from persistent to non-persistent
and the other way around.
This is to allow starting a VM with some device attached temporarily.
When VM is not running, it is possible to attach device only
persistently, so this change will allow to do that, then, after starting
the VM, change it to non-persistent - so it will not be attached again
at further startups.

storage/lvm: fix Volume() instance init when physical volume is unavailable
First, cache objects created with init_volume - this is the only place
where we have full volume configuration (including snap_on_start and
save_on_stop properties).
But also implement get_volume method, to get a volume instance for given
volume id. Such volume instance may be incomplete (other attributes are
available only in owning domain configuration), but it will be enough
for basic operations - like cheching and changing its size, cloning
etc.
Listing volumes still use list of physically present volumes.

This makes it possible to start qubesd service, without physical
presence of some storage devices. Starting VMs using such storage would
still fail, of course.

vm/dispvm: add auto_cleanup property, unify creating new DispVM
Add auto_cleanup property, which remove DispVM after its shutdown
- this is to unify DispVM handling - less places needing special
handling after DispVM shutdown.

New DispVM inherit all settings from respective AppVM. Move this from
classmethod `DispVM.from_appvm()`, to DispVM constructor. This unify
creating new DispVM with any other VM class.
Notable exception are attached devices - because only one running VM can
have a device attached, this would prevent second DispVM started from
the same AppVM. If one need DispVM with some device attached, one can
create DispVM with auto_cleanup=False. Such DispVM will still not have
persistent storage (as any other DispVM).

Tests included.

tests: even more agressive cleanup in tearDown
Remove some more references to objects holding (possibly indirectly)
reference to libvirt connection:
 - local variables in tearDown function
 - running Admin API calls (especially admin.Events)
 - vmm._libvirt_conn directly, in case some reference to Qubes()
   is still there
 - any instance attribute that is an object from 'qubes' python package
   (instead of just those descending from BaseVM)
 - do not create new Qubes() instance for removing VMs - if we already
   have one in self.app

Then trigger garbage collector to really cleanup those objects (and
close relevant file descriptors). It's important do do this before
closing event loop, because some of descructors may try to use it (for
example remove registered handlers).

 (implemented version were wrong on so many levels...)
 - use 'save_on_stop'/'snap_on_start' properties directly instead of
 obsolete volume types
 - don't call sudo - qubesd is running as root
 - consistently use path, path_cow, path_source, path_source_cow

api/admin: split vm.volume.Clone to CloneFrom and CloneTo
The first operation returns a token, which can be passed to the second
one to actually perform clone operation. This way the caller needs have
power over both source and destination VMs (or at least appropriate
volumes), so it's easier to enforce appropriate qrexec policy.

The pending tokens are stored on Qubes() instance (as QubesAdminAPI is
not persistent). It is design choice to keep them in RAM only - those
are one time use and this way restarting qubesd is a simple way to
invalidate all of them. Otherwise we'd need some additional calls like
CloneCancel or such.

api/admin: firewall-related methods
In the end firewall is implemented as .Get and .Set rules, with policy
statically set to 'drop'. This way allow atomic firewall updates.

Since we already have appropriate firewall format handling in
qubes.firewall module - reuse it from there, but adjust the code to be
prepared for potentially malicious input. And also mark such variables
with untrusted_ prefix.

There is also third method: .Reload - which cause firewall reload

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: 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()

admin: implement admin.vm.volume.Import
Implement this in two parts:
1. Permissions checks, getting a path from appropriate storage pool
2. Actual data import

The first part is done by qubesd in a standard way, but then, instead of
accepting all the data (which may be several GB), return a path to which
a shell script (in practice: `dd` command) will write the data.
Then the script call back to qubesd again to report success/failure and
qubesd response from that call is actually returned to the user.

This way we do not pass all the data through qubesd, but still can
control the process from there in a meaningful way. Note that the last
part (second call to qubesd) may perform all kind of verification (like
a signature check on the data, or so) and can also prevent VM from
starting (hooking also domain-pre-start event) from not verified image.

storage: add Pool.import_data to the API
Allow importing not only from another volume, but also raw data. In
practice, for all currently implemented storage pools, this is the same
as Pool.export, because path returned there is read-write. But lets not
abuse this fact, some future implementation may need different methods.

admin: raise QubesNoSuchPropertyError for non-existing properties
Accessing non-existing property is a common action (for example
hasattr() do try to access the property). So, introduce specific
exception, inheriting from AttributeError. It will behave very similar
to standard (non-Admin-API) property access.

This exception is reported to the Admin API user, so it will be possible
to distinguish between non-existing property and access denied. But it
isn't any significant information leak, as list of valid properties is
publicly available in the source code.

devices: adjust XML serialization of device options
Use '<option name="option_name">option_value</option>' instead of
'<options option_name="option_value"/>'. It's more consistent with the
rest of qubes.xml - have one thing per element.

Also, add options deserialization test.

vm: don't try to define libvirt domain when just checking its state
When libvirt domain is not defined, it isn't running for sure.
This commit fixes the case when vm.is_running() appears anywhere in the
code used during libvirt xml building. In this case, it's mostly about
PCI device description for libvirt.

devices: add assignment.device property
Make it easy to retrieve DeviceInfo object out of DeviceAssignment
object. The only missing piece of information for that is device class,
so add it. Make it optional, as it can be filled on demand when passing
the object through DeviceCollection (either by listing devices, or
attaching/detaching).

This is mostly to ease handling options in libvirt template - to get
them, you need to use `assignments()`, istead of `persistent()` or
`attached()`, but there were no _simple_ way of getting actual device
object.

This also makes DeviceCollection._device method not needed anymore.
