lib/db: Remove deprecated implementation of db_set_login() and replac…

…e it with that of db_set_login2() (#4308)

`db_set_login()` is deprecated in 7.8.0 release with da399c5. Change its function signature and implementation to match that of the currently preferred `db_set_login2()`. Technically, this is removing the old function and introducing a new one with the same name, but a different signature.

Modify `db_set_login2()` to internally call `db_set_login()` function call. In the next major version, `db_set_login2()` should be removed to have only one method to get login details for simplicity.

See also #4308.
