netcat

FreeBSD base userland最近的动作实在是太慢了，所以我觉得应该做点什么。

这次感谢Kris大长辈帮忙在 pointyhat 上测试，将 bzip2 升级到了 1.0.4 版本。

另外，今天还升级了 netcat 到 OpenBSD 4.1 的版本，这个版本所作的改动非常小。

I have imported the latest OpenBSD netcat (a.k.a. nc(1), a very handy debugging utility) implementation to FreeBSD -CURRENT and the current plan is to MFC the stuff after one month’s settle.

And seems that they have re-implemented it… Why netcat… I can’t understand it…
