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.
(Re-landing changeset a6a847452dbf, backed out in 5091aa6083c4, because it was originally landed with the incorrect bug number.)

This is a rollup of the following patches
- Change the interpretation of FrameMetrics.mZoom to a "resolution-indepedent zoom", instead of a resolution-depedent scale factor. r=roc
- Remove mention of "meta" from TabChild. r=roc
- Remove some useless logging. r=roc
- Tag FrameMetrics with its composition bounds at paint time. r=roc
- Add a helper to calculate the render resolution for a FrameMetrics. r=roc
- Add a helper to compute the approximate CSS dimensions a FrameMetrics will cover during composition. r=roc
- BrowserElementScrolling doesn't actually care about zoom or resolution. r=roc
- Accept the viewport that content has calculated, when it's received the latest widget geometry update. r=roc
- Mechanically separate uses of zoom/resolution based on new definitions. r=roc
- Convert GetViewportInfo()'s resolution-dependent scale into resolution-indepedent zoom. r=roc
- Reinterpret defaultZoom == 0.0 as "intrinsic scale". r=jwir3,roc
