`nsPresContext` should use `mozilla::PresShell` directly instead of `nsIPresShell`. This patch makes it. Unfortunately, `nsPresContext` and `nsIFrame` have `PresShell()`. Therefore, we cannot use `PresShell*` in its methods so that this patch uses `mozilla::` namespace prefix. It might be better to rename them as `PresShellPtr()` in another bug.
