Detailed Description

Represents the layout of the stack when saving the context of a task.

The context of a task consists in saving all of the registers and the program counter.

Warning: This in fact is a mixed representation of the original layout of the task and the saved layout of the task.
In the original layout (when the task is allocated) we are not interested in the registers. And in the saved layout (when the context is saved, e.g. preemption) we are not interested in the termination callback.
