TESTING_JS_MODULES uses testing-common, not gre. So we should replace gre with testing-common for mochitest.

We will obsolete StyleAnimationValue in the future, and can treat
AnimationValue as a wrapper of RawServoAnimationValue to hide the FFIs
at that moment. For now, we still need both types, so it's better to make sure
they are mutually exclusive in AnimationValue. Therefore, let's add some
assertions.
Besides, I think those FFIs might do many things and it seems those methods
are not critical, so let's move them into the cpp file, so we can remove
some dependencies to avoid re-compiling so many files if someone needs
revise ServoBindings.h.

This switches over layout's usage of PLArena to ArenaAllocator. This allows
us to build more files in unified sources and gets rid of various CONST masks.

This also removes the TABLE_ATTRS_DIRTY optimization. Constructing nsMappedAttributes isn't really expensive and we do it all the time anyway.

Note that this removes the useless (because this anon box is never absolutely
positioned) "clip: inherit" style.

This will allow the session store to store and restore scroll positions (and pinch zoom on Android) for past session history entries as well, whereas today only the scroll position of the current page is saved.
As a LayoutHistoryState saves its PresStates in a hash table that doesn't allow direct access to its contents if you don't already know the entry's key, we provide a function to iterate over all stored PresStates and retrieve their keys, which can then be used to get access to each individual PresState in turn. Since nsPresState is little more than a fancy struct and we don't want to have to turn it into a full-blown XPCOM-compatible interface, we just pass the scroll/zoom-related values we're interested in as in/out parameters from/to JS via the LayoutHistoryState.
We also require a helper method for initialising an SHEntry's LayoutHistoryState, since normally this doesn't happen until the PresShell wants to capture the history state in it. We on the other hand require a LayoutHistoryState to be present immediately after creation of a fresh SHEntry object, so we can feed it the session store data during history restoration.

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.

For Android we want to be able to set a global zoom factor that will scale any page where font inflation is not turned on.
Android makes the system font scale available as a float factor. For our purposes, converting this to a percentage based value and rounding to an integer is accurate enough and enables us to pass this value as a standard Gecko int preference. This means we can make use of the standard infrastructure for setting and retrieving Gecko-side preferences both from Java and JS (the latter during testing), as opposed to having to write custom JNI and C++/IDL helper functions.
To that effect, we implement a method for retrieving that setting via nsLayoutUtils, analogous to the current font inflation settings. Since we later want to clamp the effective text zoom resulting from that setting by zoom.minPercent and maxPercent, we add var caches for them in nsLayoutUtils as well.

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.

These changes allow us to asynchronously load pre-loaded stylesheets, in a way
that's similar to ChromeUtils.compileScript. The new method returns a Promise
which resolves to the preloaded sheet once it's finished loading.
This will allow us to remove the last remaining use of synchronous channels in
moz-extension: URLs.
