This PR proposes tests to highlight #164, and also a fix that makes dylink's import functions behave like Python's. From the commit message of the ``fix'' part,
dy_import_module_symbols (akin to Python's from MODULE import *)
now correctly skips names that start with an underscort ("_"), and
dy_import_module (akin to Python's import MODULE) now does
correctly import these names.
