Support of FlexLib I/O in Core2Chip & chip plugins (alpha).

* New: In cumulus/plugins/core2chip/, support for the FlexLib I/O cells
    symbolic abstracts ("niolib"). More flexible way of specifying the
    number and positions of the various power pads, both I/O power and
    core power.
      For niolib (FlexLib I/O abstract), support for multiple clocks,
    that is, clock become ordinary pad (with signals typed as CLOCK).
* New: In cumulus/plugins/chip/, added support for niolib and final
    integration of multiple clocks (only for niolib).
