We want to use a similar model as Chrome on Android does for scaling our display of web content, that is use font inflation for desktop pages and plain text zooming for everything else.
Since we don't want to simply clobber any text zoom that might have been set by the user/front-end code, we allow setting and storing the system font scale separately on the PresContext. We then calculate the effective text zoom value as the product of the system font scale and the current text zoom value.
Any function that is using the PresContext's TextZoom value for layouting/rendering is switched over to this new EffectiveTextZoom value, whereas functions that are interested in the text zoom as actually set by the user/front-end (e.g. the nsDocumentViewer, or the code responsible for copying text and full zoom settings into the new PresContext on page navigation) continue using the plain TextZoom value.
As long as font inflation is enabled in principle (e.g. font.size.inflation.minTwips != 0), every page starts out as eligible for font inflation until the relevant meta viewport tags marking the page as "mobile friendly" have been detected. Since the PresShell caches the font inflation state and only recalculates it when necessary, we make use of that and set the PresContext's system font scale as necessary whenever the font inflation state has been refreshed.

This patch exists to avoid a crash in layout/style/test/test_animations.html. We end up
generating some ::before content, which causes us to style the new subtree at [1]. In
StyleNewSubtree, we fail the !postTraversalRequired assertion because
PrepareAndTraverseSubtree decided to traverse the tree twice (once to style it, and again
to restyle it for animations), and return that a post-traversal is needed.
The reason this issue happens with my NAC patches and not without is that we were previously
filtering out generated ::before content from the servo traversal, so the servo traversal
wouldn't have reached it and (presumably) the animation restyle wouldn't have happened and
we wouldn't have returned true for needing a post-traversal.

In this patch I introduce a new actor: PServiceWorkerUpdater managed by
PServiceWorkerManager and running on PBackground. Each time a SoftUpdate() or
Update() operation starts, a PServiceWorkerUpdater is used for having a unique
lock for the update of a particular scope+originAttributes.
The implementation happens on the PBackground thread of the parent process,
where all these PServiceWorkerUpdater actors are taken in an array and, only
the first one for each scope+originAttributes is activated.
When we shutdown the browser while the GMPService is active we can end up
leaking a GMPParent, GeckoMediaPluginServiceParent, and a Runnable. I tracked
this down to the runnable dispatched to the GMP thread in
GMPParent::ChildTerminated(). The dispatch of this runnable is failing as we
are dispatching the runnable to a reference of the GMP thread which we have
previously acquired, but that thread is now shutdown. So the dispatch fails,
and if you look in nsThread::DispatchInternal() you'll see that we deliberately
leak the runnable if dispatch fails! The runnable leaking means that the
references it holds to the GMPParent and the GMP service parent leak.
The solution in this patch is to not cache a reference to the GMP thread on the
GMPParent; instead we re-request the GMP thread from the GMPService when we
want it. This means that in the case where the browser is shutting down,
GMPParent::GMPThread() will return null, and we'll not leak the runnable. We'll
then follow the (hacky) shutdown path added in bug 1163239.
We also need to change GMPParent::GMPThread() and GMPContentParent::GMPThread()
to return a reference to the GMP thread with a refcount held on it, in order
to ensure we don't race with the GMP service shutting down the GMP thread
while we're trying to dispatch to in on shutdown.

When the agent is audible, we should check whether need to notify "blockStart"
immediately.

Since the window would know when need to resume the media, we don't need the
add/removeMediaContent() anymore.

We should let window decide whether resume the media component, not document.
Because we might have media component which is not in DOM tree, but we still
want to play it.
Window should be resumed when all following conditions are true,
(1) the tab is in the foreground
(2) there is any alive media component (MediaElement/WebAudio/PlugIn...)
(3) the window is blocked (nsISuspendedTypes::SUSPENDED_BLOCK)

Per bug 1322570 Comment 7, we could drop the GetParentAllowServo() when we
invoke UpdateProperties() from a SquentialTask, so allow it for now.

We often need to turn on both MediaSample and MediaDecoder logs when debugging sample activities.
So it is convenient to merge them into a single log module.
Use `MOZ_LOG=MediaDecoder:4` to show decoder logs.
use `MOZ_LOG=MediaDecoder:5` to show both decoder and sample logs.

1. Use LOG() for OnMediaSink{Audio,video}Complete() which is not verbose.
2. Use LOGW() for OnMediaSink{Audio,Video}Error() which indicates an error.

This allows us to remove the #ifdef MOZ_ENABLE_WEBRENDER for the advanced layers
prefs from all.js. As additional advanced layers are turned on for webrender (or
non-webrender) they can be converted into override prefs without affecting the
call sites.

X11.h #defines 'Status' and 'Failed' and 'Succeeded' which conflicts with
the enum in DetailedPromise. So rename the 'Status' enum in DetailedPromise
so that the build works on Linux.
Some of my changes here caused DetailedPromise to be included in more
places that it was before, which caused build failures on Linux.

This severs the ChromiumCDMVideoDecoder's connection with the CDM. The CDM process
will shutdown when the MediaKeys also severs its connection.
