* checkpoint before removing CT from change trie * before trie backend without tx * undo * Started no transaction, but would need using a different root calculation method, out of the scope of this pr, will roll back. * Remove NoTransaction. * partially address review. dummy stats implementation for no_std. * Remove ChangeTrieOverlay. * modified function * Remove witness_ext * need noops changes root * update from cumulus branch * line break * remove warning * line break * From review: renamings and stats active in no std (except time). * include cache, exclude change trie cache with individual temporary bad looking no_std check * little test * fuse imports and filter_map prepare_extrinsics_input_inner fold. * put back ExtInner into Ext, awkward double proto for new function. * Apply suggestions from code review * Update primitives/state-machine/Cargo.toml Co-authored-by: Bastian Köcher <bkchr@users.noreply.github.com>
