Erik Ernst	614ae7f362	Integrated covariant parameter feature specs. ... Also updated spec on the static and dynamic types of functions literals and static functions along with the function objects obtained from closurizations of them. Introduced a separate notion of what it means to be a correct override relation (where the old text used subtyping, which won't suffice, for several reasons). Introduced the notion of interfaces as a separate kind of entity that contains method signatures (again, a new kind of entity), thus clarifying exactly which pieces of information is available during static analysis of member accesses, e.g., instance method invocations. Introduced 'combined' interfaces; they are needed for `mixin` declarations, and we will specify them soon (so it should be OK to have them now, even though they are unused).
