Debian use /usr/lib/python*/dist-packages (instead of site-packages) for
packaged python modules. It's achieved using --install-layout=deb
option, so pass it on Debian build.
Installing grub on root.img require some space before the filesystem.
Create it by adding partition table to root.img. This commit take care
of assembling dmroot device when such partition table is present, while
preserving compatibility with partition-less images.

This hook require new device nodes to appear in /dev. If devtmpfs is
used, it's not a problem ("simple" initramfs case), but otherwise udevd
is needed - and it isn't running in pre-udev hook yet.

Send just one value - used memory (which is calculated anyway),
instead of full input data. This greatly simplify parsing at qmemman
side.

dracut has apparently moved from /sbin to /bin some time in the past.
Accommodate this change to avoid failures.

Archlinux now support pacman hooks that automatically handle both
building modules through dkms and rebuilding the initcpio.
For this reason, support scripts are not required anymore.
For example do not exclude (from exposing to qvm-block) loop devices
with this flag set, otherwise `qvm-block -l` would not list just
attached disk image files.
FixesQubesOS/qubes-issues#2453
For example, attaching a device-mapper device to another VM increases
its "dmsetup info" open count in is_used(), which triggered its removal
from qvm-block.
The canonical device name is not necessarily used in /proc/mounts or
/proc/self/mountinfo, see /dev/dm-0 vs. /dev/mapper/dmroot. (And only
checking by major:minor is not possible in the case of btrfs.)
Also fixes another bug where e.g. dm-10 would match when really only
dm-1 was mounted, or when the mountpoint path included the device name,
etc.
Also catches enabled swap.
Apparently some devices do not comply with standards (there is no such
thing as USB version 2.01), but other than that works fine. So take into
account only the major number of bcdUSB field.
FixesQubesOS/qubes-issues#2158
Those devices are most likely attached using "PV USB" from another
domain, so it doesn't make sense to list them as available for further
passthrough.
QubesOS/qubes-issues#531
Even if particular PV USB implementation doesn't support it, still have
it included in QubesDB. It should be up to attaching code to decide.
Also, don't fail if xen-usbback module doesn't exist. This isn't the
only option (the other one is usbip over qrexec).
QubesOS/qubes-issues#531
During early dom0 boot, before xenstored is started any access to it
through /proc/xen/xenbus (or /dev/xen/xenbus) will wait until xenstored
is started. If that happens in script ordered to start before xenstored,
we have a deadlock. Prevent this by using `xenstore-ls -s` in dom0,
which will fail immediately when xenstored isn't running yet. This fail
isn't a problem, because when xenstored isn't running yet, surely device
isn't attached anywhere.
QubesOS/qubes-issues#1081
This prevents simultaneous attachment of the same device (in practice)
to multiple VMs.
This change to be effective requires udev action being called when such
device is attached/detached to some domain. Script
/etc/xen/scripts/block will take care of it.
FixesQubesOS/qubes-issues#1081
Exclude exclude device if mounted/part of other device, or any of its
partition is used (same definition). Update this state whenever device
or it's partition receives udev event.
