   Memory layout of old block is as follows:

   +-------+---------------------+-+--------------------------+-----------+

        *saved               saved memblock
 
   Memory layout of new block is as follows:
   +-------+-----------------------------+-+----------------------+-------+
   |  ...  |    "new_padding" bytes      | | ... "size" bytes ... |  ...  |
   +-------+-----------------------------+-+----------------------+-------+

          temp                       saved memblock
 
   However, in the new block, actual data is still written as follows
   (because it was copied by realloc):
   +-------+---------------------+--------------------------------+-------+
   |  ...  | "old_padding" bytes |   ... "old_size" bytes ...     |  ...  |
   +-------+---------------------+--------------------------------+-------+

          temp                       saved memblock
 
   Therefore, min(old_size,size) bytes of actual data have to be moved
   from the offset they were at in the old block (temp + old_padding),
   to the offset they have to be in the new block (temp + new_padding == memblock).
