Introduce configuration variables for the Ring router. 

* New: In MBK, read new environment variables for ring router
    RING_WMIN_ALU1, RING_DMIN_ALU1, ...
* New: In RDS, in rprparse.c add entry in table MBK_WIRESETTING for the
    new ring variables.
* Change: In RDS, in rfmaccess.c, degenerate a BIGVIA into a default VIA
    when one of it's side is inferior to SIDE*1.5. This allow ring to
    keep it's 6x6 BIGVIAs.
