7e2f0f9a36 fix(library/unifier): in the context_check, we should not consider local constants that occur in the type of other constants

We were missing higher-order pattern constraints due to this bug.

e513b0ead4 refactor(library,hott): rename theorems for decidable and inhabited 
The convention is this: we use e.g. nat.is_inhabited and nat.has_decidable_eq
for these two purposes only, to avoid clashing with "inhabited" and "decidable_eq"
in a namespace. Otherwise, we use "decidable_foo" and "inhabited_foo".
