NETMAP plugin

I *finally* pushed out the Bro NETMAP plugin into the Bro package manager. This is the same thing that was in the old plugins repository that has now been deprecated. I would appreciate if people would try it if you use NETMAP. It can be installed like this:

  bro-pkg refresh
  bro-pkg install bro/bro-netmap

You can read some more directions about how to use it in the repository here:
