Bruce Evans 87543489d0 Cleaned up previous commit, mainly by moving repetitive calculations
of invariants to cyattach().

Fixed minor bugs:
- cyparam() returned without restoring the ipl in the error cases.  This
  was harmless because cyparam() is always called at spltty().
- one check for "rev. J or higher" actually checked for precisely rev. J.
