* Fix copyright year * Show elapsed times with enabled `CoreDb` API tracking * Show elapsed times with enabled `LedgerRef` API tracking * Reorg `CoreDb` auto destructors for `Aristo` DB why: While `Aristo` supports some parallelism for concurrent database access, this comes with a price of management overhead. With a naive approach, the auto-destructor will slow down execution because the ledger and evm treat the database in a shared mode where a DB descriptor is just created and thrown away shortly after. This is reflected in the `Coredb` abstraction layer above `Aristo`/`Kvt` where a few `Shared` type descriptors are cached and a shared reference is returned rather than a disposable new object. * For `CoreDb` support transaction level tracking details: This is mainly an extra for the legacy DB as `Aristo` and `Kvt` support this already. Also return an error on the legacy DB backend when `persistent()` is called while there are transactions pending (the `persistent()` call does nothing otherwise on the legacy backend.) * Clear compiler warnings (remove unused variables etc.)
