specified, it will consist only of LGPLed source.
The tests-related module list is the transitive closure of the specified
modules, including tests modules, minus the main module list excluding
modules of applicability 'all'. Its lib/* sources (brought in through
dependencies of *-tests modules) go into $testsbase/. It may contain GPLed
source, even if lgpl is specified.
Arguments are basemodules and finalmodules, where basemodules argument
represents modules specified by user and finalmodules represents modules
list after previous transitive_closure.
Method returns tuple which contains two lists: the list of main modules and
the list of tests-related modules. Both lists contain dependencies.
