The nsCSSFrameConstructor bits are now handled in PresShell::Destroy along with
the other refresh driver observers.
I cleaned up the nsRefreshDriver methods because they were using infallible
append anyway, and that simplified the logic.

PresShell only uses performane.now to track refresh times, and notify internal
observers. We can provide more accurate times by not clamping and jittering
these numbers.

The font face set is owned by the document now, and the shell knows about
refresh driver ticks. There's no reason for it to live in the pres context.

This code was originally added to debug the frame visibility code.
However it wasn't architected correctly and makes the compositor use an
untrusted layers id from content. Instead of fixing this I'd rather just
delete it, since it's a big pile of code that is basically a debugging
tool that nobody owns anymore.

This switches `nsNodeInfoHash` to a nsDataHashTable. The hash function and
equality operator are moved to NodeInfoInner so that they can be easily reused.

Most of them just want GetRootFrame(), and there's no need to explicitly go
through the frame manager for that, we have a handy alias in the shell.

-Wmissing-prototypes is a new optional warning available in clang ToT. It warns about global functions that have no previous function declaration (e.g. from an #included header file). These functions can probably be made static (allowing the compiler to better optimize them) or they may be unused.
Confusingly, clang's -Wmissing-prototypes is equivalent to gcc's -Wmissing-declarations, not gcc's -Wmissing-prototypes. A function prototype is a function declaration that specifies the function's argument types. C++ requires that all function declarations specify their argument types, but C does not. As such, gcc's -Wmissing-prototypes is a C-only warning about C functions that have no previous function *prototypes* (with argument types), even if a previous function *declaration* (without argument types) was seen.

mNeedStyleFlush is also set by animation restyle request. So it's possible
that the flag is set again in PostRestyleForThrottledAnimations() or in
sequential tasks for updating animations after the flag is cleared at the top
DoFlushPendingNotifications().

This unfortunately doesn't fix my test-case (because we're replacing the text
content all the time and all that), but it's still worth it, since it fixes the
case we care about (the parser appending).
We could also optimize pure insertions (since in that case we can still figure
out what the old text was), but it's probably annoying and not worth the churn.
In any case, we cannot optimize anything that resembles any kind of removal,
because from there we don't know the old text in any way (and the text nodes
like to reuse string buffers and such).
We could do two other optimizations to replace / extend this one, in that order:
* Pass the buffer and length to CharacterDataWillChange, and use that to get
the exact old text and the new one in RestyleManager. That would make the
optimization exact.
* Pass some sort of Maybe<bool> mWasWhitespace down the CharacterDataChangeInfo
which is computed like:
HasFlag(NS_CACHED_TEXT_IS_ONLY_WHITESPACE)
? Some(NS_TEXT_IS_ONLY_WHITESPACE)
: Nothing()
It's not clear to me it's going to be completely worth the churn, so I haven't
done those yet, if we see code in the wild which resembles my testcase, we can
think of doing it.

Also, make them not rebuild the CascadeData synchronously, via the
FlushSkinSheets call, since that's broken. That fixes bug 1413119.

The autofocus attribute on form elements forces layout in CheckIfFocusable.
To avoid unpleasant FOUCs, defer autofocus processing until frames are
constructed in PresShell::Initialize.
Resolve the race between nsAutoFocusEvent running and page load by checking the
readystate at time of event posting. Skip autofocus if the element moved to a
different window in the meantime.

Instead, just post the reframe, and process them normally on the next style
flush.
The assertion happens because the observer is triggered due to a doc ltr -> rtl
change, which triggers style invalidation. There's nothing processing the
restyles resulting from that invalidation before we hackily go into frame
construction from there, and thus we assert that the styles aren't up-to-date.

I left some IgnoredErrorResults for now where people warn on failure. We could
consider adding a WarnOnError() thing or something.

Everything that needs them up-to-date will call flush appropriately, there
should be no need to do it manually.
This way we coalesce all the stylist updates until the next style flush in the
best case, or until one of the consumers actually needs them.

So that we can now ensure nsRefreshDriver ticks (i.e. nsRefreshDriver doesn't
stop its timer) for all queued events.
Before this patch, dispatching CSS animation/transition events relied on the
fact that DocumentTimeline observes nsRefreshDriver. For this fact,
animationcancel or transitioncancel event did not dispatch properly in some
cases, i.e. the case where the animation was dropped from the DocumentTimeline.
