Jim Warner d310a18fc2 top: exploit new kb_main_available, make Jaromir happy 
This patch will trade a former pessimistic calculation
of free physical memory for a more optimistic one that
uses the newly added kb_main_available library export.

But in case one might wish to return to the old former
method, there's a new #define that was made available.

[ the new calculation will affect graphing mode only ]
