This reworks bug 1440561 so that we only precompute loads that belong to our
user font set, avoiding messing up with fonts in the cache that belong to other
pages.
The loadability of a font is precomputed in PreTraverse in the same way as we
did, but only for the fonts that we may end up loading. This is stored in
FontFaceSet now.
Also, the principal shenanigans that this code did are reworked to be explicit
about when the document principal changes in ResetToURI, instead of having a
member around and a mutable variable. This makes the code easier to follow.

Currently we can only have one type of WebRenderUserData on an Item. We already
have a hash table of WebRenderUserData so it's not hard to include type in the
hash to support one per type.

More improvements to come. In particular, this still iterates through Shadow DOM
in each_xbl_cascade_data, but that should be changed later. That allows to
cleanup a bunch of stuff and finally fix Shadow DOM cascade order.
We still rely on the binding parent to be setup properly in the shadow tree, but
that requirement can go away later (we can walk the containing shadow chain
instead).
This mostly focuses on removing the XBL binding from the Shadow host.
It'd be nice to do EnumerateShadowRoots faster. I think that should also be a
followup, if needed.

Also, make them not rebuild the CascadeData synchronously, via the
FlushSkinSheets call, since that's broken. That fixes bug 1413119.
This is a little step in getting rid of XBL usage for Shadow DOM.

This removes a hack, but adds slightly more complex code in inspector-only code.
I'm not excited about this code, but this fixes ServoStyleRuleMap for XBL.

The keyframe stuff runs from animation building, which needs clean styles
already.
Same for counter styles, they run from a well-defined point in time where rules
should be up-to-date already.
The canvas stuff needs no stylist access mostly, since it's only used to compute
a couple font-related things.

The reason why bug 1355721 regressed this is because in non-e10s we definitely
flush before parsing the standards quirks-mode. And bug 1355721 introduced an
unconditional UpdateStylistIfNeeded, unless the counter style / font
equivalents.
That means that the stylist wouldn't remain on its initial state after the first
flush, which itself means that when the compat mode changed, the UA and user
rules were already on the stylist with the quirks mode keys. That makes
class-names be keyed in ascii lowercase.
After that no user style changed, so no rebuild happens for the cascade data in
the user origin, so we keep looking at the wrong keys indefinitely.

This will make it easier to handle it properly for Shadow DOM, though this patch
doesn't do that.
This also makes some method inline and infallible for convenience, since nobody
checks the errors anyway.

This avoids resetting the computed values all the time, and paves the way to
avoid using a StyleSet on XBL bindings / Shadow DOM, which we should really
really do because it's super overkill.
There are some XBL bits that are kind of hacky, in particular the mStylistDirty,
but they'll go away soon, since I want to redo how we store styles in XBL.
The alternative, which was returning an array of indices or something was even
more hacky I think.

This will allow us to invoke it from nsAttrValueInlines.h, which can't
include ServoStyleSet.h due to circular dependencies.

The selectorText test happens to pass right now because well, we don't implement
the setter yet[1], but would fail if we implemented an specific invalidation in
the way I'd have done it yesterday.

This also removes some confusing comments around nsIDocument regarding some kind
of "special" stylesheets, which don't seem to exist anymore, and consolidates
StyleSheetList so that we only have one implementation.
I think that fixes a potential leak on the shadow root code (even though the API
is v0 only), given the pointer from the ShadowRootStyleSheetList to the
ShadowRoot wasn't being CCd.
Also, more stuff could be renamed, methods removed, etc, feel free to suggest
more cleanup, I've done mostly the minimal.
Next steps are moving the stylesets there and stop using the proto binding sheet
list / resources.

See bug 1422633, there are assertions missing, and servo doesn't assert at all
anymore.
I don't think it's worth optimizing / lazily resolving it, each time the
document state changes.
We usually just restyle the world anyway (which requires recomputing it), and
the changes that it's optimizing (nsWindow::SetActive() and XUL root element
localedir attribute changes) aren't common enough to warrant the complexity I'd
say.
This doesn't handle invalidating the cache in the case the root element goes
away, I haven't bothered because it was already broken, and GetRootElement() is
already gone in RemoveSubtreeFromDocument.

This also makes the rule map not process all the stylesheets for the document,
which would be a mess with shadow DOM.
Far from the final, ideal state, but hey, progress.

In the current implementation, we call SetStylistStyleSheetsDirty() every time
a style sheet is changed. However, the dirty bit setting may or may not always
update the style data. For example, the style data for undisplayed elements are
deliberately not updated in Stylo. However, the getComputedStyle API is supposed
to provide a way to get the up-to-date computed style data, even for undisplayed
elements.
In this patch, we increment RestyleGeneration for undisplayed elements when we
call SetStylistStyleSheetsDirty(). This could flush the cached data that
getComputedStyle API holds, and ensures the getComputedStyle API computes a new
one.

This is a pre-patch for the real fix of Bug 1418433.
In the real fix, we'll add a IncrementUndisplayedRestyleGeneration() call into
SetStylistStyleSheetsDirty(). However, the IncrementUndisplayedRestyleGeneration()
call needs get through some deep structures in nsPresContext, RestyleManager,...
etc., and doing so means we need to move bunches of related include files, forward
declarations, from .cpp file to .h file, which doesn't make sense.
Instead, we move the implementation parts of SetStylistStyleSheetsDirty() to .cpp
file (since it is now a bit more complicated than it was), so we can use the existing
include files in the .cpp file to add IncrementUndisplayedRestyleGeneration() call
(this is in a following patch).
