 * Functions for copying atoms properties.

 * All of them receive, as the input, the property to be copied, the destination
 * buffer, and a pointer to an offset in the destination buffer to copy to the right place.
 * This offset will be updated to the new value (offset + copied_size)
 * The functions return the size of the property that has been copied or 0
 * if it couldn't copy.
