PS1: 
Finally I did what I was talking about, probing v2
It still has few things to do, I added comments for myself, plus polish - but I wanted to share early so that we can discuss!

My main goal was to have the same logic (and code) for probing in cli and libflashrom, but as an additional consideration,
in the context of CB:87251 I am thinking this might also solve the programmer capabilities question - since it now returns info of all matches.
