I rebased and made the changes, removing the various ways to pass a stat. Now it's more specific, and should be easier to mantain. I also changed the counters input to an nlp input, because there is no easy way to access the counters type of a NLPModel.

Updated and rebased. I created AbstractExtraStats for the specific solver stats.

Is there anything else to fix in this?
