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.

This piggybacks the sync message on the pre-existing
EnsureLayersConnected sync message pathway to the compositor.

This call should be a no-op in the real world, and should be safe to
remove. The patch also adds an assert to ensure that the call is
effectively a no-op.

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.

There is already a GetLayersId function in RenderFrameParent.h that does the
exact same thing, and this private function is only used in one spot. Seems
unnecessary.

This completes the migration of code from the github branch to the graphics
project repo. At this point all webrender-related code should be disabled
unless --enable-webrender is provided in the mozconfig.

We will use the new type for the generated IPDL message handler
prototype to make sure correct error handling method is called.

The class ViewportFrame doesn't have ns-prefix, so it's better to drop the
ns-prefix in the file names to avoid confusion.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
