Remove src/core/ and src/feature dependencies from confparse.c

This C file will eventually belong in lib/confmgt, so it needs to
have only low-level dependencies.  Now that it no longers needs
routerset.c, we can adjust its includes accordingly.

I'm not moving the file yet, since it would make fixup commits on
earlier branches here really hard to do.
