Needless to say, when one copies and then pastes, it's
always better when those results are refined somewhat.
The qsort callback declarations used the wrong results
type and 2 of their 3 input parameters were wrong too.
So this patch will fix that & generalize declarations.
[ plus add comment guidance about noop & extra enums ]
[ & provide for 'noop' sorting, as is done in <PIDS> ]
