Fix use after free when dropping zerowidth data
Commit ec42b42ce601808070462111c0c28edb0e89babb added an optional
pointer for each cell, thus some old code that was optimizing copying
with 'ptr::copy' was duplicating "unique" pointers ('Box'), which was
resulting in use after free, after attempting to free both of these
pointers.
By replacing these unsafe blocks with safe Rust, the issue itself is
fixed and the potential for future memory problems is eliminated from
this area of the code.
