Daniel Lezcano 47c4b0de08 tools/lib/thermal: Add a thermal library
The thermal framework implements a netlink notification mechanism to
be used by the userspace to have a thermal configuration discovery,
trip point changes or violation, cooling device changes notifications,
etc...

This library provides a level of abstraction for the thermal netlink
notification allowing the userspace to connect to the notification
mechanism more easily. The library is callback oriented.
