Abstraction of a task within the kernel abstraction layer (KAL).
This module abstracts the concept of task/thread from the scheduler perspective. It allows to associate generic "opaque" data to a thread, to retrieve the numeric unique identifier of a thread, to retrieve the effective user and group identifier, to check if a task is ready to run, and to change a task scheduling policy so to force the kernel to schedule it.
