Pablo Neira Ayuso 14506665d9 add libgtpnl
This patch adds the libgtpnl library. Harald mentioned that he wanted
that the specific code that is added is well encapsulated, so let's
start a small library to interact with the GTP kernel module via netlink

This was done a bit while in the rush, so the interfaces are not nice
at all and the tools need to be ported on top of this library.

This library will be used to integrate openggsn with the GTP kernel
