* fix inaccurate log
* terraform: refactor EvalWriteState
EvalWriteState is refactored into a method on
NodeAbstractResourceInstance and renamed writeResourceInstanceState.
Import, my nemesis, gave me pause. I did not expect to find
EvalWriteState in an transform node, and so I decided to copy the
function inline rather than rethink my entire refactor for one function
that's likely to be (heavily) refactored in the future.
* Split node_resource_abstract.go into two files, putting
NodeAbstractResourceInstance methods in their own file - it was getting
large enough to be tricky for (my) human eyeballs.
* un-exported the functions that were created as part of the EvalTree()
refactor; they did not need to be public.
