Root package now contains only initialization code and 'dummy' module. Each module now got its own package. Module packages are grouped by their main purpose (storage/, target/, auth/, etc). Shared code is placed in these "group" packages. Parser for module references in config is moved into config/module. Code shared by tests (mock modules, etc) is placed in testutils.
