Formalize the mechanism for storing mapped (non-filesystem) filenames in the filenames array. These are not compared against input or output files for overwrite checks. Add the infrastructure for comparing more than one input filename (future proofing.) Move the Makefile dependency target name to the filenames system. Signed-off-by: H.
