- Push Giant down into linker_reference_module().

- Add a new function linker_release_module() as a more intuitive complement
  to linker_reference_module() that wraps linker_file_unload().
  linker_release_module() can either take the module name and version info
  passed to linker_reference_module() or it can accept the linker file
  object returned by linker_reference_module().
