Support for wiring rules in RDS. Rounding error in rprparse (second try).

* New: In RDS tables, add rules describing the wiring for the router and
    the cell gauge. This do not scritly respect the fact that RDS deals
    only with the symbolic to real translation and programs that are
    purely symbolic should not access it. But is is the simplest way to
    provides them with default configuration, whithout using environement
    variables.
      So now, ocp and nero do read the rds configuration file, but only
    for the symbolic wiring rules informations.
      Modification contributed by N. Shimizu.
* Change: In <mbk>, in mbk_utils.c, nowadays all C libraries supplies the
    tolower() function, so no longer use our own. And besides it was causing
    problems in the static initialization when both rds and mbk environement
    where loaded together.
      Modification contributed by N. Shimizu.
* Bug: In <rds>, In rprparse.c in RprTranslateParam() there was a rounding
    error again. We cannot simply adds 0.5 as this function could be called
    for *negative* values. Instead, use lround() C function (round in
    opposite directions for positive or negatives integers).
