Breakout page_order() to internal.h to avoid special knowledge of the buddy allocator
The statistics patch later needs to know what order a free page is on the free lists. Rather than having special knowledge of page_private() when PageBuddy() is set, this patch places out page_order() in internal.h and adds a VM_BUG_ON to catch using it on non-PageBuddy pages.
