qubes/backup: misc fixes 
Fix restoring ProxyVM and NetVM from core2. Use correct VM class.

qubes/backup: include LVM volumes content in backup 
Use just introduced tar writer to archive content of LVM volumes (or
more generally: block devices). Place them as 'private.img' and
'root.img' files in the backup - just like in old format. This require
support for replacing file name in tar header - another thing trivially
supported with tar writer.

qubes/backup: fix relative path calculation 
os.path.relpath strip trailing '/.' from the path, but it is important
to distinguish whole-directory archive (which is tar of '.').

backup: adjust LVM volume size when restoring its content. 
Old backup metadata (old qubes.xml) does not contain info about
individual volume sizes. So, extract it from tar header (using verbose
output during restore) and resize volume accordingly.
Without this, restoring volumes larger than default would be impossible.

backup: support relocating files to different storage pool 
To ease all this, rework restore workflow: first create QubesVM objects,
and all their files (as for fresh VM), then override them with data
from backup - possibly redirecting some files to new location. This
allows generic code to create LVM volumes and then only restore its
content.

qubes/backup: better handle restoring kernel=None case 
It makes sense for HVM domains, so allow such configuration.

backup: open backup collection in offline mode 
Otherwise it may try to manipulate live libvirt objects with the same
names (and probably different UUIDs, which would fail).

2261e6a4c7 backup: simplify auto-renaming handling

actual restore time.

processes_to_kill_on_cancel shouldn't be initialized by user, so move
below applying user settings.

b4227f7581 backup: use simple classes instead of hashes, use events for appmenus 
This makes typo errors much easier to find (also using pylint or so).
While at it, also removed explicit appmenus backup, as it should be
provided by appmenus extension.

c01f43a5d3 backup: unify handling of template and non-template VMs 
Handle them the same way - individual files, not the whole directory for
templates.
Also don't backup obsolete 'kernels' subdir - it isn't supported in
core3.

Introduce two main classes Backup and BackupRestore for storing the
state of the desired operation. Then a simple interface to adjust
parameters.
