Hi~ All~

COLO Frame, block replication and COLO proxy(colo-compare,filter-mirror,
filter-redirector,filter-rewriter) 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.

For the neweset version, please refer to:
https://github.com/zhangckid/qemu/tree/qemu-colo-18jun1

Please review, thanks.

V8:
 - Rebased on upstream codes.
 - Addressed Markus's comments in patch 10/17.
 - Addressed Markus's comments in patch 11/17.
 - Removed some comments in patch 4/17.
 - Moved the "migration_bitmap_clear_dirty()" to suitable position in
   patch 9/17.
 - Rewrote the patch 07/17 to address Davie's comments.
 - Moved the "qemu_savevm_live_state" out of the
   qemu_mutex_lock_iothread.
 - Fixed the bug that in some status COLO vm crash with segmentation fault.

V7:
 - Addressed Markus's comments in 11/17.
 - Rebased on upstream.

V6:
 - Addressed Eric Blake's comments, use the enum to feedback in patch 11/17.
 - Fixed QAPI command separator problem in patch 11/17.
