Rework system font lookup under OSX so that the style system passes around the same "meta" name used by Webkit, -apple-system. This makes it so that the hidden system fonts used aren't exposed to authors. It also allows us to handle the two optical sizes of font families used under OSX 10.11, which uses San Francisco as the new UI font, with one family for text sizes and another for larger, display sizes. The patch here: - moves system font lookup into gfxMacPlatformFontList - assigns the font family name to "-apple-system" - derives FindFamily to take a gfxFontStyle parameter to allow size-based lookups - maintains a list of hidden system font families (not exposed to authors) - maintains a mapping from -apple-system to the underlying hidden font families
