Read only_db restriction from a dedicated session key

Browse Source 
da_login.php now stores the ticket's restrict_db into
DA_MYSQL_PHPMYADMIN_RESTRICT_DB, and config.inc.php's only_db builder
reads that key instead of the landing-page db field, so an
all-databases login (empty restrict_db) leaves phpMyAdmin unrestricted.
