If you accept it, I'll try to fix the race condition on snapshot writing.

Hi all,
It's the new patch for the multiple snapshot support for the VMDK format.
I rewrote the previous one according to the new multiple snapshots
concept, introduced by Fabrice.
The snapshots can be created with standard way:
qemu-img create –b base-image.vmdk –f vmdk snapshot-img-001.vmdk
We can create the snapshots chain in this way.
The patch include also the 'CID' protection that defined by the VMDK
format.
The CID is a value updated on the first write every time the virtual
disk is opened.
P.S. Fabrice, I used the bdrv_pread() and bdrv_pwrite(), as you advised
me.
Regards,
Igor Lvovsky
