Progress: featureless make.

Update appropriate f_utf_ functions.

Implement "define" and "parameter" IKI variables as per IKI-0002.
These variables will be substituted with settings value if found or removed if not found.
This expansion will happen before performing operation.

rename fake_make_load_setting() to fake_make_load_fakefile() to be more explicit.

Minor cleanups.
