This adds MSD support to the check functions, as well as adding a check
to make sure the domain in question actually exists on the source system.

I was thinking maybe you could condense these functions some. Instead
of having a transport field in the job struct, you could have a uri field.
So, you could have a function that is called get_msd_values() that has
everything from get_msd_check_values() except the virConnectPtr /
connect_by_classname() part. get_msd_check_values() would just call
get_msd_values() plus the connect_by_classname() bit.
Then the check functions could call get_msd_check_values() and the
migrate functions could call get_msd_values().
Probably not worth the reordering and work though.
Otherwise, I have no issues here. This set tested fine on my system.

There is also the array processing that the check version does. I
experimented with this a little and we ended up having a little
overlap and then a special case for both. Given the rather small size
and the possibility for more special cases later, it didn't seem worth
the mess of combining them.

Sorry, I know my comment comes a bit late, as the patch is already
checked in.
I think this check is not enough. To check if a certain
Xen/KVM_ComputerSystem or the Xen/KVM_HostSystem object path is correct
specified by the client, you should use the corresponding (new ;))
interfaces (get_domain_by_ref, get_host), as they check the complete
object path for correctness. It raises the number of cycles a bit, but
makes the behavior of all providers consistent. Thanks.

Well, the reason I added this is twofold: (1) because of the fact that
we would fail late if the domain doesn't exist, and (2) because I use
the dom pointer later for the external check code.
So, I'm more than happy to add in the more rigorous checks, but we
need this part as well :)
