* Disable `TransactionID` related functions from `state_db.nim` why: Functions `getCommittedStorage()` and `updateOriginalRoot()` from the `state_db` module are nowhere used. The emulation of a legacy `TransactionID` type functionality is administratively expensive to provide by `Aristo` (the legacy DB version is only partially implemented, anyway). As there is no other place where `TransactionID`s are used, they will not be provided by the `Aristo` variant of the `CoreDb`. For the legacy DB API, nothing will change. * Fix copyright headers in source code * Get rid of compiler warning * Update Aristo code, remove unused `merge()` variant, export `hashify()` why: Adapt to upcoming `CoreDb` wrapper * Remove synced tx feature from `Aristo` why: + This feature allowed to synchronise transaction methods like begin, commit, and rollback for a group of descriptors. + The feature is over engineered and not needed for `CoreDb`, neither is it complete (some convergence features missing.) * Add debugging helpers to `Kvt` also: Update database iterator, add count variable yield argument similar to `Aristo`. * Provide optional destructors for `CoreDb` API why; For the upcoming Aristo wrapper, this allows to control when certain smart destruction and update can take place. The auto destructor works fine in general when the storage/cache strategy is known and acceptable when creating descriptors. * Add update option for `CoreDb` API function `hash()` why; The hash function is typically used to get the state root of the MPT. Due to lazy hashing, this might be not available on the `Aristo` DB. So the `update` function asks for re-hashing the gurrent state changes if needed. * Update API tracking log mode: `info` => `debug * Use shared `Kvt` descriptor in new Ledger API why: No need to create a new descriptor all the time
