[sv-cc] Updated 1716 proposal (rand/randc)

I've updated the proposal for Mantis item #1716.  It deals with qualifiers,
like rand and randc, which have no corresponding C semantics and 
can appear with data types that DPI otherwise handles.

The changes address concerns or suggestions from Doug Warmke and
Jim Vellenga:

. The text now emphasizes that the C side does not 'zero out' or manipulate
  any extra bits associated with the qualifier in any way.

. Various changes in the last F.5 paragraph either simplify or clarify the text.

Thanks for the feedback.
