Filter-rewriter is a part of COLO project.
So this patch set depend on colo-compare.

from primary,and rewrite tcp packet's seq to the primary from
secondary.

  - add some comments
  - remove conn_list_lock
  - fix offset set bug

v2:
  - add more comments about packet flows
  - add some trace-event
  - add seq offset ( = secondary_seq - primary_seq)

v1:
  - initial patch
