Use this function to release all the memory that was allocated to the segment p. Note that after calling this function the segment is still usable, only the memory that it handled was released. If you do not need the segment anymore call the function alloc_FinishSegment() that calls this function and then releases the memory allocated to store the segment information.
Sloppy programmers may pass NULL as argument, it just returns.
