Expose a JS-friendly subset of sqlite3_config() to JS, with the notable caveats that (1) setting up the JS bindings requires starting the library, making sqlite3_config() illegal to call and (2) calling sqlite3_shutdown() in order to make it legal to call sqlite3_config() may undo certain JS-side library initialization. Move sqlite3_(de)serialize() into the int64-mode-only bindings because of their int64 args.
