* when appending log field only do so by minimal amount * move slice utils to separate package to fix import cycle, add GrowJust() and AppendJust() functions * fix GrowJust() not returning slice of same length * improved xslices tests * make AppendJust() test check for slice contents, fix AppendJust() final copying behaviour * add a +1 with field growth to try minimise allocation for log 'msg' field
