This commit does not change to any code and behavior. It it is easily reviewed with the --color-moved=dimmed_zebra git diff option. Motivation for this change is to: - Consolidate redundant functions IsBDBFile /ExistsBerkeleyDatabase / SplitWalletPath, and IsSQLiteFile / ExistsSQLiteDatabase in the next commits - Detect SQLite wallets consistently regardless whether bitcoin is built with SQLite support in the next commits - Avoid attempting to open SQLite databases with the BDB library when bitcoin is built without SQLite support in the next commits
