I think that when DYNIX/ptx appeared and people started porting things to
work on it, other maintainers assumed that the symbol _SEQUENT_ was
interchangeable with the symbol sequent, and removed one or the other,
breaking things.  So in addition to the code fixes, I've added notes about
what these symbols mean...

Dynix has a load average type of long.

LDAV_CVT for Dynix should be n/1000, so define FSCALE.  Also, I moved the
#ifdef FSCALE outside the #ifndef FSCALE because as it was the Suns here
got the wrong answer.  I wonder how this escaped notice for so long...
