The main bug fixed here is that in half of our interfaces, we use "is browser frame/element" to mean "browser or app", and in the other half, we use it to mean "is browser not app".
There's a related, functional bug also fixed here, which is that a browser process doesn't inherit its parent's app-id. This causes problems e.g. for IndexedDB: If a browser inside an app uses IndexedDB, the DB should have the app's app-id.
I also modified Tab{Parent,Child} and nsFrameLoader to call "app" "ownOrContainingApp", to emphasize that we might have inherited the app from a parent process. I left nsIDocShell::appId alone, because changing that would have necessitated changing nsILoadGroup and therefore a /lot/ of users in Necko; it's also not clear it would have clarified anything in those cases.

1. SystemMessageInternal: Handle the "_listeners" correctly by using "manifest" and "winID"
2. SystemMessageManager: Remove cpmm message listerners when receiving "inner-window-destroyed"; Add winID for the reg/unreg message.
3. DOMRequestIpcHelper: Check aTopic in observe method
The code to handle MediaStream URIs is almost the same as for Blobs, so share it.
nsHostObjectProtocolHandler is modified a bit to simplify method names. Also
we make nsHostObjectProtocolHandler::AddDataEntry take responsibility for
generating the URI to avoid duplicating that code later.
We need separate subclasses for each kind of host object protocol handler,
but we don't need separate subclasses for each kind of host object URI.
