[performance] minimise log field allocations ()
* 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
