Dawid Zamirski a4919338ba vbox: Correctly generate drive name in dumpxml 
If a VBOX VM has e.g. a SATA and SCSI disk attached, the XML generated
by dumpxml used to produce "sda" for both of those disks. This is an
invalid domain XML as libvirt does not allow duplicate device names. To
address this, keep the running total of disks that will use "sd" prefix
for device name and pass it to the vboxGenerateMediumName which no
longer tries to "compute" the value based only on current and max
port and slot values. After this the vboxGetMaxPortSlotValues is not
needed and was deleted.

* the machine settings path.
* Then, if the machine current snapshot xml file is saved in the machine location,
* it means that this snapshot was previously modified by us and has fake disks.
* Fake disks are added when the flag VIR_DOMAIN_SNAPSHOT_CREATE_CURRENT was not set
* yet, in order to not corrupt read-only disks. The first thing to do is to remove those
* disks and restore the read-write disks, if any, in the vboxSnapshotXmlMachinePtr struct.
* We also delete the current snapshot xml file.
*
* After that, we are going to register the snapshot read-only disks that we want to redefine,
* if they are not in the media registry struct.
*
* The next step is to unregister the machine and close all disks.
*
* Then, we check if the flag VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE has already been set.
* If this flag was set, we just add read-write disks to the media registry
* struct. Otherwise, we save the snapshot xml file into the machine location in order
* to recover the read-write disks during the next redefine and we create differential disks
* from the snapshot read-only disks and add them to the media registry struct.
*
* Finally, we register the machine with the new virtualbox description file.
