initramfs: add support for root.img with partition table
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.

initramfs: move qubes_cow_setup hook to pre-trigger
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.

initramfs: use units of sectors in sfdisk call
New version of sfdisk have different syntax for other units (suffixes
beside the numbers, instead of global --unit). The only common unit is
sector, so use that.

It should be 1GB, not 1MB...

dracut: add a safety check preventing qubes_cow_setup.sh running in dom0
Theoretically it shouldn't be a problem, because module isn't installed
in initramfs by default (in dom0), but since such error would be fatal
to dom0 (will prevent it from booting), add a safety check for it.

Probably it will be required when (if) we migrate dom0 to Debian

debian: introduce qubes-kernel-vm-support package
This package is responsible for kernel modules and initramfs additions
needed in Qubes VM. When installed, it is possible to switch the VM to
use PV Grub and load the kernel from inside of VM. This greatly ease
installing custom kernel modules.

Changes:
 - make qubes_cow_setup.sh working with both dracut and initramfs-tools
 - add initramfs-tools configuration/scripts (including
         qubes_cow_setup.sh)
 - modify DESTDIR to handle multiple binary packages out of single
   source

dracut: add dmsetup --noudevsync since we're running in pre-udev hook
When udev is installed (and scheduled to be started), but not running
yet, plain dmsetup will deadlock on waiting for udev. Since we call
`dmsetup mknodes dmroot` anyway

dracut: split 'full' dracut module into 'full-dmroot' and 'full-modules'
When PV Grub will be used, VM initramfs should not contain /lib/modules
mounting code, as the VM root.img will already contains kernel modules.
Make it possible by splitting the module.
