78693c265c qubes/vm/qubesvm: rework QubesVM.run*() methods
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.

mgmt: move property value sanitization to property definition
This also means we don't check if a VM with given name (in case of
VMProperty) exists in the system, at this stage. But this is ok, lets
not duplicate work of property setter.

qubes/vm: disconnect from old QubesDB when going to start new instance
QubesDB daemon no longer remove socket created by new instance, so one

to ensure that we really connect to the new instance, instead of talking
to the old one (soon to be terminated).

qubes/vm: don't fail on removing VM without files
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.

qubes/vm/net: add feature of hiding real IP from the VM
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.

    core: use runuser instead of sudo for switching root->user

    There are problems with using sudo in early system startup
    (systemd-logind not running yet, pam_systemd timeouts). Since we don't
    need full session here, runuser is good enough (even better: faster).

commit 2265fd3d52
Author: Marek Marczykowski-Górecki <marmarek@invisiblethingslab.com>
Date:   Sat Jun 4 17:42:24 2016 +0200

    core: start qubesdb as normal user, even when VM is started by root

    On VM start, old qubesdb-daemon is terminated (if still running). In
    practice it happen only at VM startart (shutdown and quickly start
    again). But in that case, if the VM was started by root, such operation
    would fail.
    So when VM is started by root, make sure that qubesdb-daemon will be
    running as normal user (the first user in group 'qubes' - there should
    be only one).
