FS: Add a struct for modes
Browse files Browse the repository at this point in the history 
As suggested here: https://dolp.in/pr7059#pullrequestreview-125401778

More descriptive than having a std::tuple of FS::Mode, and lets us
give names to known triplets of modes (like in ES). Functions that
only forward mode arguments are slightly less verbose now too.
