This commit took 2 days (26-27.01.2016) and put our friendship to test.

It should be created at VM creation time (or template changes commit).
But for example for HVM templates created before implementing
QubesOS/qubes-issues#1573, there would be no such image. So create it
when needed, just before VM startup
FixesQubesOS/qubes-issues#1602
We still can't support running HVM template and its VMs simultaneously
(easily), but still, have root-cow.img handled for HVM template, to
allow qvm-revert-template-changes.
FixesQubesOS/qubes-issues#1573
- QubesVmStorage provides now a default get_config_params() method which should
be enough for all possible Storage implementations.
- When writing a custom Storage implementation, one has just to reimplement the
following methods:
* root_dev_config()
* private_dev_config()
* volatile_dev_config()
- QubesVmStorage provides a default implementation of other_dev_config(),
because it can be shared by all storage implementations
The method XenStorage._format_disk_dev() generates the xml config for a device.
It is not specific to the Xen file storage implementation. It can and must be
reused by other storage implementations
This makes easier to handle some corner cases. One of them is having
entry without `dir_path` defined. This may happen when migrating from R2
(using backup+restore or in-place) while some DisposableVM was running
(even if not included in the backup itself).

Reported by @doncohen, thanks @wyory for providing more details.
We use only one device-mapper layer for HVMs, and this isn't the same as
for PV - it is that one, which PV does in initramfs.
Device-mapper layers summary for template-based VMs:
PV: root.img+root-cow.img (dom0) -> xvda, xvda+volatile.img (VM)
HVM: root.img+volatile.img (dom0)
