net/filter-mirror:Add filter-mirror
Filter-mirror is a netfilter plugin.
It gives qemu the ability to mirror
packets to a chardev.
usage:
-netdev tap,id=hn0
-chardev socket,id=mirror0,host=ip_primary,port=X,server,nowait
-filter-mirror,id=m0,netdev=hn0,queue=tx/rx/all,outdev=mirror0

In COLO-compare, we do packet comparing job.
Packets coming from the primary char indev will be sent to outdev.
Packets coming from the secondary char dev will be dropped after comparing.
colo-comapre need two input chardev and one output chardev:
primary_in=chardev1-id (source: primary send packet)
secondary_in=chardev2-id (source: secondary send packet)
outdev=chardev3-id
usage:
primary:
-netdev tap,id=hn0,vhost=off,script=/etc/qemu-ifup,downscript=/etc/qemu-ifdown
-device e1000,id=e0,netdev=hn0,mac=52:a4:00:12:78:66

filter-rewriter: introduce filter-rewriter initialization
Filter-rewriter is a part of COLO project.
It will rewrite some of secondary packet to make
secondary guest's tcp connection established successfully.
In this module we will rewrite tcp packet's ack to the secondary
from primary,and rewrite tcp packet's seq to the primary from
secondary.
usage:
colo secondary:
-object filter-redirector,id=f1,netdev=hn0,queue=tx,indev=red0
-object filter-redirector,id=f2,netdev=hn0,queue=rx,outdev=red1
-object filter-rewriter,id=rew0,netdev=hn0,queue=all
