Martin Stein abf9557bb5 AVL node/tree: make non-copyable ... AVL trees can't be copied with the default copy constructor as the parent pointer of the first item of both of the resulting trees would point to the original tree. Copying an AVL node, however, generally violates the integrity of the corresponding tree. The copy constructor of Avl_tree is used in some places but in those places it can be replaced easily. So, this commit deletes the copy constructor of Avl_node_base which makes Avl_node and Avl_tree non-copyable. Issue #2654		2018-02-09 13:34:23 +01:00
