The definition of which submodules are of interest by the user is tied to the configuration submodule.<name>.url; when it is set to a non-empty string, it is of interest. We'd want to be able to later change this definition, but there are many places that explicitly check this condition in the scripted Porcelain.
Introduce the "is-active" subcommand to "submodule--helper", so that the exact definition of what submodule is of interest can be centrally defined (and changed in later steps). In a few patches that follow, this helper is used to replace the explicit checks of the configuration variable in scripts.
