The event regions override flags are needed whenever APZ is doing
hit-testing off the layer tree. This can happen even if
IsBuildingLayerEventRegions() returns false, because we can instead be
building nsDisplayCompositorHitTestInfo items from which we populate the
layer tree's EventRegions objects. So the guard condition here is wrong,
and we can just remove it to ensure the flags are always put on the
layer tree. If APZ isn't enabled on this layer tree then they won't be
used, and there might be a slight perf hit, but it should be negligible.

We should always have the pipeline information for in-process things like
async images, but for cross-process iframes we might not have the information
right away if the content process doesn't get around to sending it for a while.

The new struct is in LayersTypes.h, all the rest of the changes are just
replacing existing uint64_t instances with the new LayersId struct.
Note that there is one functional change, in
CompositorBridgeParent::DeallocPWebRenderBridgeParent, where we now
correctly convert the PipelineId to a LayersId before using it to index
into sIndirectLayerTrees, whereas before we were incorrectly just using
the mHandle part of the PipelineId.

-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.

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

It was using the visible rect of the display item before, which can be larger
than the frame for various reasons. But the bounds we pass for the webrender
iframe item determines the iframe's position, so it needs to be informed by the
layout position of the frame, not by circumstances of the paint.

Instead of the WebRenderLayerScrollData code knowing about all the
different display item types, it makes more sense to move this logic
into the display items.
In addition to avoiding dis-encapsulating the data from nsDisplayItem subclasses,
this makes it easier to handle two specific scenarios:
(1) the case where an nsDisplayItem A subclasses another nsDisplayItem B, but A
and B have different types returned by GetType(). Previously A and B would have
to be handled explicitly in the WebRenderLayerScrollData switch statements,
which doesn't scale well if new types are added. With the new approach the
virtual function is shared down from A to B and so takes care of it. This is
particularly relevant for types like nsDisplayOwnLayer which have a number of
subclasses.
(2) the case where a display item *might* have APZ-relevant information.
In this case the type of the item alone is not sufficient to determine
if we need to create a new WebRenderLayerScrollData for it. Instead, we
need to access specific state inside the display item. This is now
handled by the UpdateScrollData function returning true when passed
nullptr arguments, and replaces the switch statement in
WebRenderLayerManager that updated forceNewLayerData.

This adds handling for nsDisplayRemote frames, so that we create a
WebRenderLayerScrollData item for each nsDisplayRemote frame that we
encounter. This is the equivalent of a "ref layer" in a normal layer
tree, and allows the APZ side to glue together the scroll data from
different processes into a full tree.

Every JS plugin is assigned a unique ID. When an instance of a JS plugin is created the
frame loader that we use to load the plugin's handler URI will create a special
TabContext. This TabContext causes the ContentParent to use the process for this specific
JS plugin (creating one if it hasn't already) when it creates the PBrowser actors.
This causes the iframes for all the instances of a specific JS plugin to be grouped in the
same process.

Currently, we only correctly support remote layer trees for frameloaders that
use the same layer manager as their document. Since we need to be able to host
remote <browser> content in popup widgets for remote WebExtensions, we need to
tie the frameloaders to the layer manager of their host element, rather than
the root layer manager for the document.

The goal of this patch is to remove the call to the sync IPC
GetCompositorOptions message from TabChild::InitRenderingState. In order
to this, we have InitRenderingState take the CompositorOptions as an
argument instead, and propagate that backwards through the call sites.
Eventually we can propagate it back to a set of already-sync IPC
messages in PCompositorBridge that are used during layers id
registration (NotifyChildCreated, NotifyChildRecreated, etc.). Therefore
this patch effectively piggybacks the CompositorOptions sync IPC onto
these pre-existing sync IPC messages.
The one exception is when we propagate it back to the AdoptChild call.
If this message were sync we could just use it like the others and have
it return a CompositorOptions. However, it is async, so instead we add
another call to GetCompositorOptions here temporarily. This will be
removed in the next patch.

There are scenarios where we have a TabParent in the UI process hooked up to
a PuppetWidget with a BasicLayerManager. Webextensions fall into this category.
In this scenario, the parent-side layer manager is not hooked up to
the compositor (that is, there is no entry in the CompositorBridge layer tree
state map for the layers id). However, the content-side still ends up creating
a ClientLayerManager or a WebRenderLayerManager, which expects the layers id to
be registered in the compositor. This results in brokenness (in the case of the
ClientLayerManager/PLayerTransaction) or crashes (in the case of WebRenderLayerManager/
PWebRenderBridge). Instead, this patch changes this scenario to have the content
process use a BasicLayerManager which seems safer.

Instead we can use the otherwise-unused function to check if initialization worked.
Technically, because of the way RenderFrame construction works, whether or not
initialization succeeds is exactly dependent on whether or not the frameloader is
non-null, so we could even just use that to check success. But this feels slightly
more readable/cleaner.

Rewrite VsyncRefreshDriverTimer::GetTimerRate to always use the cached
value of the vsync rate in VsyncChild to avoid processing events on
the main thread.
Since VsyncChild::GetTimerRate is called in VsyncRefreshDriverTimer's
constructor, that cached value is bound to be set soon. This should
make the period of time we need to guess in
VsyncRefreshDriverTimer::GetTimerRate very short.
