Use [apply path_forall], not [apply funext]
Less restrictive Funext_downward_closed

Fixups to work with the latest polyproj branch.
Progress on adapting HoTT and categories to latest polyproj branch.
Progress on adapting HoTT and categories to latest polyproj branch.
Adapt categories and hit's code to latest polyproj (Private keyword).
- A few places raise universe inconsistencies in Categories still, not sure why.
- Some minor unification problems with apply/eauto discovered as well.
- Some places requiring more instances of Funext, as I expected.
Everything compiles quickly here.
