Updated the FSControl code to make the copy operation use a dynamic area, instead of the free pool.  The maximum size of this dynamic area is set as the size of the 'next' slot.  This prevents the problems associated with

*copy where it will claim all the free memory, thus stoppping for example
filecore from growing its directory buffer, or zap from growing its dynamic
area.  This makes multiple *copies in task windows usable.
