New library

I have almost finished switching the LQL library to libnl, the netlink library. It supports more queuing disciplines but seems to be a bit less mature in terms of development. I have been adding bits of code to it as I start to understand how it works.

So far, parsing from XML is working, as well as parsing to XML (the save feature). Next up, is to port the CLASSIFY iptables extension into libnl and to extend the XML parse/safe format to include it.
