Move computation of key locations into diff model

This is a preparation of change 373057. We want to the model to be
responsible for diff processing. So it needs to control the key
locations, which are one of the processing inputs.

We are also moving the information about currently attached comment
widgets into the model, which will be valuable in other changes. So
you have one place to look up information about potentially existing
comments. See change 373406 for how this will be used later.
