usbmon: Add class for binary interface

Browse Source 
Add a class which allows for an easier integration with udev.

This code was originally written by Paolo Abeni, and arrived to my tree
as a part of big patch to add binary API on December 18. As I understand,
Paolo always meant the class to be a part of the whole thing. This is his
udev rule to go along with the patch:

KERNEL=="usbmon[0-9]*", NAME="usbmon%n", MODE="0440",OWNER="root",GROUP="bin"
