There's only one case of sync frame construction from ContentRemoved now, and
it's not on the element being removed, but on the whitespace siblings if needed,
and _only_ when they don't support lazy frame construction.
Basically, this switches all the RecreateFramesForContent calls to use
`aAsyncInsert` (which I changed to an enum class for readability), except when
we're already reframing.
Also, it switches ReframeTextIfNeeded to opt-in into lazy frame construction,
since it's used only when aFlags == CONTENT_REMOVED.
This allows to simplify the DestroyFramesFor API (which I'm happy to rename to
something more meaningful, since now it's something like
DestroyFramesForAndRecreateThemAsync), and do some other consistency cleanups.
A bunch of the ContentRemoved callsites were pretty random at passing
aAsyncInsert, and that was some kind of a mess. This patch ensures consistency,
and makes it impossible to do O(n^2) work when removing DOM nodes, which is
nice.
The underlying reason for this is explained in the description of bug 1377848,
and basically allows us to remove a bunch of Servo hacks on the longer term (a
few of them are going away already, yay!).

Now that we do process normal traversal even in the case of throttled animation
flush so that we don't need to do special handling for the case.
Note about the comment in has_current_styles():
the remaining animation hints is not caused by either this patch or the
previous patch in this patch series, it's been there in the first place, but
it should be fixed somehow later. See bug 1389675.

When a reframe happens on the parent of a pseudo element which has animations,
we need to grab style for the pseudo element that includes the animations'
style and also *replace* old style context (that does not include animations'
style) with it. Otherwise, we will use the old style context that has *no*
animations style, as a result, we will see a flicker right after the reframe.
Two reftests in this patch fail without this fix. One is for CSS transitions,
the other one is for CSS animations.

This removes about 2/3 of the occurrences of nsXPIDLString in the tree. The
places where nsXPIDLStrings are null-checked are replaced with |rv| checks.
The patch also removes a couple of unused declarations from
nsIStringBundle.idl.
Note that nsStringBundle::GetStringFromNameHelper() was merged into
GetStringFromName(), because they both would have had the same signature.
Removes applet tag interfaces, and changes HTML5 parser to output
HTMLUnknownElement when tag is found. Removes tag process from various
places in the browser.

This removes the two calls to `FlushPendingLinkUpdates` in nsCSSFrameConstructor
and GeckoRestyleManager, which appear to have no effect.
Looking through what the pending link code is attempting to do:
* When a new anchor is bound in `BindToTree` we do:
1. Link::ResetLinkState(false, Link::ElementHasHref());
* Set link's mLinkState to default (either unvisited or not link)
* Set element's link mState bits to default (either unvisited or not link)
2. doc->RegisterPendingLinkUpdate(this);
* Schedules idle dispatch to run `FlushPendingLinkUpdates` within 1 sec
* In `FlushPendingLinkUpdates`:
* For each pending link, call element->UpdateLinkState(link->LinkState());
1. Register link for async history update to get potential future visited
state
2. mLinkState is still unvisited / not link until we hear from history, so
element state is unchanged
Thus, there seems to be no need to call `FlushPendingLinkUpdates` outside of
`BindToTree`, since visited state is always applied async anyway (so it doesn't
work as an optimization to avoid restyling if visited, since that will trigger
later).

(This makes it behave a bit more like a normal CSS block, and it ensures that
it can provide a float manager to its descendants.)

Previous to these patches, the style resolution happening on [1] made the style
data stick on the element, so we'd never think it was the initial style, even if
it was.
This was wallpapering the fact that, if that was the initial style, we'd never
have another chance of traversing the document when [2] kicked in.
This somehow just happened to work, but is a very fishy way to get it to work.
Instead, call StyleDocument() properly _before_, and rely on the fact that it
will stop when it has a non-null binding, and only if it fails explicitly style
the children.
This fixes the few XBL test-cases with this patch series that exercise
-moz-bindings on the root element without the root being styled, and makes the
-moz-binding code more consistent in both places of the frame constructor.

In case of removing summary element, we need to check details *frame* children
instead of details *element* children since the summary element has been
already removed from details element children list.

Considering the case where the summary element has position:absolute, we need
to use inFlowFrame and its parent instead of aFrame itself.
