Removes the pointer at the given index from the pointer array.
The following elements are moved down one place. If @array has
a non-%NULL #GDestroyNotify 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).
