This patch sets up the initial changes to the migration state
machine and prototypes to be used by the checkpointing code
to interact with the state machine so that we can later handle
failure and recovery scenarios.

here is a chance that ram_save_block will never break while loop
if loat_seen_block be reset for mc when there are no dirty pages
to be migrated.
Thanks!
OK, now I have finally experienced this bug: When I deleted the netdev
network card, I get an infinite loop in ram_save_block.......
Need to figure out how to fix it =)
