Core db remove legacy phrases (#2468) * Rename `newKvt()` -> `ctx.getKvt()` why: Clean up legacy shortcut. Also, the `KVT` returned is not instantiated but refers to the shared `KVT` that resides in a context which is a generalisation of an in-memory database fork. The function `ctx` retrieves the default context. * Rename `newTransaction()` -> `ctx.newTransaction()` why: Clean up legacy shortcut. The transaction is applied to a context as a generalisation of an in-memory database fork. The function `ctx` retrieves the default context. * Rename `getColumn(CtGeneric)` -> `getGeneric()` why: No more a list of well known sub-tries needed, a single one is enough. In fact, `getColumn()` did only support a single sub-tree by now. * Reduce TODO list
