* finalization for in_mem * fetch last finalized block * pruning: use canonical term instead of final * finalize blocks in full node * begin to port light client DB * add tree-route * keep number index consistent in full nodes * fix tests * disable cache and finish porting light client * add AsMut to system module * final leaf is always best * fix all tests * Fix comment and trace * removed unused Into call * add comment on behavior of `finalize_block` * move `tree_route` to client common * tree_route tests * return slices in TreeRoute * apply finality up to parent * add `finalize_block` call * adjust formatting * finality notifications and add last finalized block to chain info * exhaustive match and comments * fix sync tests by using non-instant finality
