Bug 1187784 (part 8) - Replace nsBaseHashtable::EnumerateRead() calls in layout/ with iterators. r=heycam. This fixes a type bug in CSSVariableDeclarations::MapRuleInfoInto(). The existing code passes aRuleData->mVariables.get(), which has type |CSSVariableDeclarations*|, into the |void*| parameter to EnumerateRead(). It then extracts that in EnumerateVariableForMapRuleInfoInto() via a cast to a different type, |nsDataHashtable<nsStringHashKey, nsString>*|. It's missing an intermediate access of CSSVariableDeclarations::mVariables. It's likely that this hasn't (seemingly) caused problems prior to now because mVariables is the only field in CSSVariableDeclarations, so mVariables->mVariables is at the same address as mVariables.
