Coding Style | CPU Pinning | Removing ADT

This is a series of patches that comprise:

* CPU Pinning: flowgrindd can now bound to a given CPU (new option -c). Tested on Linux and FreeBSD
* Removing ADT code: the license of the ADT code is Debian-unfriendly. Since nobody wants a longish discussion with Debian, we simply delete the ADT stuff. No one will miss it...
* Coding Style: bracket position, indentation and line breaks according Linux Kernel Coding style
