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.

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.

0) All those methods are now awaitable rather than synchronous.
1) The base method is run_service(). The method run() was rewritten
using run_service('qubes.VMShell', input=...). There is no provision
for running plain commands.
2) Get rid of passio*= arguments. If you'd like to get another return
value, use another method. It's as simple as that.
See:
- run_service_for_stdio()
- run_for_stdio()
Also gone are wait= and localcmd= arguments. They are of no use
inside qubesd.
3) The qvm-run tool and tests are left behind for now and will be fixed
later. This is because they also need event loop, which is not
implemented yet.

Don't allow characters potentially interfering with qrexec. To be on the
safe side, allow only alphanumeric characters + very few selected
punctuations.
Split it into two functions: validate_name - context-less verification,
and actual _setter_name which perform additional verification in
context of actual VM.
Switch to qubes.exc.* exceptions where appropriate.
QubesDB daemon no longer remove socket created by new instance, so one
part of VM restart race condition is solved. The only remaining part is
to ensure that we really connect to the new instance, instead of talking
to the old one (soon to be terminated).

VM files may be already removed. Don't fail on this while removing a
VM, it's probably the reason why domain is being removed.
qvm-remove tool have its own guard for this, but it isn't enough - if
rmtree(dir_path) fails, storage.remove() would not be called, so
non-file storages would not be cleaned up.
This is also needed to correctly handle template reinstallation - where
VM directory is moved away to call create_on_disk again.
QubesOS/qubes-issues#2412
Just calling pool.init_volume isn't enough - a lot of code depends on
additional data loaded into vm.storage object. Provide a convenient
wrapper for this.
At the same time, fix loading extra volumes from qubes.xml - don't fail
on volume not mentioned in initial vm.volume_config.
QubesOS/qubes-issues#2256
This helps hiding VM IP for anonymous VMs (Whonix) even when some
application leak it. VM will know only some fake IP, which should be set
to something as common as possible.
The feature is mostly implemented at (Proxy)VM side using NAT in
separate network namespace. Core here is only passing arguments to it.
It is designed the way that multiple VMs can use the same IP and still
do not interfere with each other. Even more: it is possible to address
each of them (using their "native" IP), even when multiple of them share
the same "fake" IP.
Original approach (marmarek/old-qubes-core-admin#2) used network script
arguments by appending them to script name, but libxl in Xen >= 4.6
fixed that side effect and it isn't possible anymore. So use QubesDB
instead.
From user POV, this adds 3 "features":
- net/fake-ip - IP address visible in the VM
- net/fake-gateway - default gateway in the VM
- net/fake-netmask - network mask
The feature is enabled if net/fake-ip is set (to some IP address) and is
different than VM native IP. All of those "features" can be set on
template, to affect all of VMs.
Firewall rules etc in (Proxy)VM should still be applied to VM "native"
IP.

Instead of excerpt from /proc/meminfo, use just one integer. This make
qmemman handling much easier and ease implementation for non-Linux OSes
(where /proc/meminfo doesn't exist).
For now keep also support for old format.

There is no point in changing *public API* for just a change without any
better reason. It turned out most of those settings will be the same in
Qubes 4.0, so keep names the same.
This reverts commit 2d6ad3b60c.
