David McFarland af85fdd73f Cygwin: Fix cygheap corruption caused by cloned atomic buffer
The fhandler_base_overlapped::copyto clears atomic_write_buf on the
clone, but none of the derived classes were doing this.  This allowed
the destructor to double-free the buffer and corrupt cygheap.
Clear atomic_write_buf in copyto of all derived classes.
