Respect HW configs when loading VM from snapshots.
Changing HW configuration properties may cause emulator / guest system crash on
condition that VM has been loaded from a snapshot. This CL addresses this issue
in the following way:
1. Each time a snapshot is saved, a backup copy of HW config is saved with it.
2. Each time a snapshot is loaded, emulator finds an appropriate HW config
backup, and compares current HW config with the one that was saved in the
backup, and if configs are different, emulator exits with an appropriate
error.
