This patch changed getvirt to continue working even if spice_critical
doesn't abort (i.e. SPICE_ABORT_LEVEL != -1). This is in preparation to
make getvirt not abort at all. The reason is that getvirt is run on
guest provided memory, so a bad driver can crash the vm.
cb_get_virt and cb_validate_virt have disappeared a long time ago,
not needed since:

Properly parse QXLImage to the new-world SpiceImage
SpiceImage now replaces RedImage and has all image types in it.
All image data are now chunked (and as such not copied when demarshalling).
