 This patch changes the algorithm get_page_children uses to a faster one.
 This old algo is both recursive (so at most depth 100 on common php vm)
 and exponential in time. The one proposed on the patch is linear and
 doesn’t use recursion, which is faster and doesn’t impose a theoretical
 limit on three depth.

 Another idea is to rename the function to get_post_children as any custom
 post_type can be hierarchical, not only pages.
