make DriverWrapper public so we can use it in the API (for custom checking e.g. version)
+ reduced garbage generated in buildURL
allow for a hook (for sub-classes) where DriverWrapper is initialized
"internal" `config =` and `config ||=` helpers for the Java part
avoid the `init_connection` hook instead override `newDriverWrapper` on the Java side
avoid the `init_connection` hook in Postgres' adapter
reinvent `init_connection` (driver) hook in Java with Derby's adapter
mariadb (now) counts !
`context.runtime` it is
remove unused method + use `context.nil`
share quoting code (with prefix-suffix decoration) between impls
move PostgreSQL's `quote_column_name` into "native"
re-built jar
