Bug 1299753 Part 2 - Create block formatting context for DetailsFrame if needed. r=bz nsCSSFrameConstructor::ConstructNonScrollableBlock() has logic to determine whether to create a block formatting context for a block frame. I refactor the function to make it reusable by nsCSSFrameConstructor::ConstructDetailsFrame(). Also, make NS_NewBlockFrame() accept two arguments as other frame factory functions so that it could be pointed by BlockFrameCreationFunc. NS_NewBlockFormattingContext is changed accordingly. The construction for a scrollable DetailsFrame will be further revised in Part 3. MozReview-Commit-ID: 8TwG9YMyGva
