top: implemented more than two abreast summary display <=== port of newlib 248efdf1

Browse Source 
______________________________ original newlib message

Well, here it is. This is what the preceding series of
commits was leading to: an ability to show up to eight
cpus per Summary Area line. In reality, a self imposed
limit of four cpus on such lines seems more realistic.

In any case, the new capability could also be employed
along with that '!' toggle which consolidates adjacent
cpus into a solitary graph. When used together the '4'
and '!' toggles should accommodate any number of cpus.
