Make PackageIndex use SlotDict for package metadata storage. The set of
allowed keys is passed into the PackageIndex constructor (normal dict
instances will be used if the set of keys is not passed in for some
reason). A SlotDict.allowed_keys attribute now provides access to a
frozenset of allowed keys.
