Instead through dmsetup snapshot, which is no longer needed and only negatively impacts performance.

To reduce xvd devices count, merge it with root-cow.img. So now it will contain 2 partitions:

• root.cow
• swap.img
  (same as current root.img)

Additionally current root.img can be reduced to plain filesystem (without partition table).

Changes in:

• qubes_cow_setup.sh
• fstab
• qvm-core (reset_cow_storage, remove reset_swap_cow_storage)
• template-builder (new partition layout, clean cow.img in template)
