tipc: add new TIPC configuration tool

tipc is a user-space configuration tool for TIPC (Transparent
Inter-process Communication). It utilizes the TIPC netlink API in the
kernel to fetch data or perform actions.

The tipc tool has somewhat similar syntax to the ip tool meaning that
users of the ip tool should not feel that unfamiliar with this tool.
