RAM cache into SVM's MEMORY,
we do this in a more efficient way:
Only flush any page that dirtied by PVM or SVM since last checkpoint.
In this way, we ensure SVM's memory same with PVM's.
Besides, we must ensure flush RAM cache before load device state.

With this command, we can control the period of checkpoint, if
there is no comparison of net packets.

The 'colo_nicname' should be assigned with network name,
for exmple, 'eth2'. It will be parameter of 'colo_script',
'colo_script' should be assigned with an scirpt path.
We parse these parameter in tap.

This conversion is backwards compatible, better documented and

In addition, Fix a typo

Hi Juan Amit,
This series has been reviewed, and could you help merging them ?
Thanks,
zhanghailiang
This series converts open-coded 'str' type to enum type for 'status'.
This conversion will be more convenient for future extensibility.
Actually, I will add a MIG_STATE_COLO state for COLO
Rename all macro MIG_STATE_* to MIGRATION_STATUS_* except MIG_STATE_ERROR,
we rename it to MIGRATION_STATUS_FAILED which will match the migration status
string 'failed'.
