Instead of formatting contexts flailing around to figure out from the "inside" how much space is available on the "outside", we should provide the amount of available space in both axes as an input to run(). This basically means that when something creates a nested formatting context, the parent context is responsible for telling the nested context how much space is available for layout. This information is provided immediately when invoking run(). Note that this commit doesn't pass accurate values in all cases yet. This first step just makes it build, and passes available values in some cases where getting them was trivial.
