Editor creates a `<br>` element when it's root element is empty. Then, it's stored by `TextEditRules::mBogusNode` and used for checking whether the editor is empty quickly. However, this `<br>` element has `mozeditorbogusnode` attribute whose value is `true`. However, adding or removing the attribute is not cheap and web apps can refer such illegal attribute. Therefore, this patch makes `HTMLBRElement` take a specific flag whether it's a bogus node or not. However, this means that this hacky thing will be exposed outside editor module. For making what is the bogus node clearer, this patch calls the such `<br>` elements as "padding `<br>` element for empty editor". So, this patch also includes a lot of renaming methods and variables, and modifying related comments.
