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.
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.
1. Add a helper function on vm.storage. This is equivalent of:
vm.storage.get_pool(vm.volumes[name]).export(vm.volumes[name])
2. Make sure the path returned by `export` on LVM volume is accessible.
First part - handling firewall.xml and rules formatting.

TODO (for dom0):
- plug into QubesVM object
- expose rules in QubesDB (including reloading)
- drop old functions (vm.get_firewall_conf etc)

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.

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).

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).

Commit from core2:
commit 94d52a13e7
core: adjust guid parameters when running on KDE5
On KDE5 native decoration plugin is used and requires special properties
set (instead of `_QUBES_VMNAME` etc).
Special care needs to be taken when detecting environment, because
environment variables aren't good enough - this script may be running
with cleared environment (through sudo, or from systemd). So check
properties of X11 root window.
