Removes the pointer at the given index from the pointer array.
The last element in the array is used to fill in the space, so
this function does not preserve the order of the array. But it
is faster than PtrArray.removeIndex. If array has a non-NULLGDestroyNotify function it is called for the removed element. If so, the
return value from this function will potentially point to freed memory
(depending on the GDestroyNotify implementation).
