[PATCH 1/4] Turn `(rnrs io ports)' into an R6RS library

[Andreas Rottmann <a.rottmann@gmx.at>]

* module/rnrs/io/ports.scm: Change into an R6RS library from a "regular"
  Guile module, so the bookkeeping for #:re-export and #:replace is done
  automatically and we gain control over the imports from `(guile)'.
