Most the changes are due to InventoryObjectList* changing to LLInventoryObject::object_list_t*, LLInventoryItem::II_FLAGS* changing to LLInventoryItemFlags::II_FLAGS* and also const'ing.
Certain perms for certain asset types(callcard&landmarks) have been laxed, as per LL's V2.
LLInventoryType now does lookups mostly though new lldictionary class.
LLLandmark using boost for callbacks, instead of custom class structure.
