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
