Hi,
COLO Frame, block replication and COLO net compare have been exist in qemu
for long time, it's time to integrate these three parts to make COLO really works.
In this series, we have some optimizations for COLO frame, including separating the
process of saving ram and device state, using an COLO_EXIT event to notify users that
VM exits COLO, for these parts, most of them have been reviewed long time ago in old version,
but since this series have just rebased on upstream which had merged a new series of migration,
parts of pathes in this series deserve review again.
We use notifier/callback method for COLO compare to notify COLO frame about
net packets inconsistent event, and add a handle_event method for NetFilterClass to
help COLO frame to notify filters and colo-compare about checkpoint/failover event,
it is flexible.
Besides, this series is on top of '[PATCH 0/3] colo-compare: fix three bugs' series.
For the neweset version, please refer to:
https://github.com/coloft/qemu/tree/colo-for-qemu-2.10-2017-4-22
Please review, thanks.

COLO: Add block replication into colo process
COLO: Load dirty pages into SVM's RAM cache firstly
ram/COLO: Record the dirty pages that SVM received
COLO: Flush memory data from ram cache
qmp event: Add COLO_EXIT event to notify users while exited COLO
savevm: split save/find loadvm_handlers entry into two helper
functions
savevm: split the process of different stages for loadvm/savevm
COLO: Separate the process of saving/loading ram and device state
COLO: Split qemu_savevm_state_begin out of checkpoint process
COLO: flush host dirty ram from cache
filter: Add handle_event method for NetFilterClass
