* Refactor database and config init Connect to the database without loading full config Load config completely so post-processing is always done consistently. Erase existing $config when loading, fixes issues in case we load the config twice. If the database is not connected, don't try to load database settings. (Fixes some db errors on install) Attempt to remove $config access/modification before init.php Remove usage of db_name, that might not match the connected database. Centralize db config loading, so we consistently apply db_test database settings. Many of these changes are influenced by Laravel port. * Some safety so we don't assign strings to numeric port field Smooth out phpunit bootstrap * Fix a couple of scrutinizer warnings.
