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.

tools/lib/thermal: Fix sampling handler context ptr The sampling handler, provided by the user alongside a void* context, was invoked with an internal structure instead of the user context. Correct the invocation of the sampling handler to pass the user context pointer instead. Note that the approach taken is similar to that in events.c, and will reduce the chances of this mistake happening if additional sampling callbacks are added.

tools/lib/thermal: Fix thermal_sampling_exit() thermal_sampling_init() suscribes to THERMAL_GENL_SAMPLING_GROUP_NAME group so thermal_sampling_exit() should unsubscribe from the same group.
