Initially, IPCInternal{Request,Response} had contained IPCStreams which would
result in unecessary copying when sending the objects over IPC. The patch
makes these streams either:
1) ParentToParentStream (just a UUID)
2) ParentToChildStream (a PIPCBlobInputStream actor, acting as a handle)
3) ChildToParentStream (a real IPCStream)
These three types are union-ed together by the BodyStreamVariant IPDL structure.
This structure replaces the IPCStream members in IPCInternal{Request,Response}
so that, depending on the particular IPDL protocol, we can avoid cloning streams
and just pass handles/IDs instead.
As a side effect, this makes file-backed Response objects cloneable. Initially,
these Responses would be backed by an nsFileInputStream, which is not cloneable
outside the parent process. They are now backed by IPCBlobInputStreams, which
are cloneable.
One thing that's not really satisfactory (IMO), is the manual management of
IPCBlobInputStreamStorage so that no streams are leaked, e.g. if we store a
stream in the IPCBlobInputStreamStorage but fail to send an IPC message and
therefore fail to remove the stream from storage on the other side of the IPC
boundary (only parent-to-parent in this case).

This provides web compatability with Chrome's interpretation of the spec at
https://drafts.csswg.org/css-device-adapt/#user-zoom-desc. This changes makes
us treat "the user cannot interactively change the zoom factor" as inclusive
of ANY method of the user agent changing zoom levels, regardless of whether or
not the user initiated an action.
So, in addition to preventing things like double-tap-to-zoom and pinch-zoom,
this change prevents zoom changes to fit all content into the viewport, or to
maintain visible content proportionality if the viewport is resized dynamically.
This also adds an assert to cases where Document::GetViewportInfo returns a
viewport with a non-positive scale factor that it also sets the auto scale
flag.
This also adds a tentative web-platform test.

Adds IpdlQueue capability to PWebGL actors. The WebGLChild, used in content processes, implements SyncProducerActor and AsyncConsumerActor because it sends (sync and async) messages and receives responses to them that it reads as async messages. The WebGLParent, used in the compositor process, is a SyncConsumerActor and AsyncProducerActor for dual reasons.
Differential Revision: https://phabricator.services.mozilla.com/D68264
The IpdlQueue (de)serializes types into arrays that are then passed to another process via IPDL messages. This means much less bloat than generating IPDL routines for each of the commands we send with WebGL. This IPDL queue is fairly basic -- it simply sends "async" commands through an async IPDL message and sync commands through a sync message. Future extensions, such as a facility for buffering async messages to be sent in bulk, are planned.
The IpdlQueue uses an existing actor to send messages. That actor should derive from one of the provided base classes and implement any needed IPDL message. For example, if the actor is used as the comsumer for sync messages then it should subclass SyncConsumerActor and should Recv (via IPDL) the ExchangeIpdlQueueData message -- the handler method for which is defined in the SyncProducerActor base class.

We need to separate WebGL actor construction and initialization since IpdlQueue initialization needs the actor to already exist.

Move QueueParamTraits, which are common between PCQ and IpdlQueue, to a file they both include. This also changes the namespace of a handful of the classes, like the Marshaller.

* Templatize ProducerView/ConsumerView/(Sync)CommandSource/(Sync)CommandSink to allow both Pcq and Ipdl versions, as the client code is identical.
* Rename Producer/Consumer -> PcqProducer/PcqConsumer.

* Remove CommandSink from WebGLMethodDispatcher. The parameter is unneeded.
* Make MethodDispatcher code simpler. This removes a layer of complexity (CommandDispatchDriver) involved in finding the correct method for a given ID number.
* Require WebGL methods whose signatures don't allow them to be remoted to directly call on the host object. They are: ReadPixels, GetVRFrame, GetInternalFormatParameter, GetBufferSubData, GetLinkResult and TexImage.
* Fix a bunch of compilation issues with busted PcqParamTraits.
* implement PcqParamTraits for some missing types

A lot of simple changes to prepare for later patches in the series:
* PcqCommand -> QueueCommand, PcqStatus -> QueueStatus, PcqParamTraits -> QueueParamTraits
* Consolidate BasicSink/Source into CommandSink/Source
* SyncCommandSource::mConsumer -> mResponseSink, SyncCommandSink::mProducer -> mResponseSource, CommandSource::mProducer -> mSource, CommandSink::mConsumer -> mSink
* Rename WebGLPcqParamTraits.h to WebGLQueueParamTraits.h
* ProducerConsumerQueue struct -> class.
* ProducerConsumerQueue::mProducer/mConsumer access -> ProducerConsumerQueue::TakeProducer/TakeConsumer
* Rename QueueStatus enum elements to follow style convention.
* Rename Status() to GetStatus() in ProducerView and ConsumerView to appease Linux.
* Rename CommandResult enum values to fit convention (and avoid Linux conflict with Success).

I am honstely still not convinced that this function should actually exists.
It seems like a convulted way of saying AtomToId, while also asserting that the atom is pinned.

After the recent simplifications to the zoom code, they only take care
of forwarding the enlarge / decrease zoom messages.
We can do that via PBrowser instead, and get rid of the actors. We can
also remove ZoomChangeUsingMouseWheel. Zooming with the mouse wheel will
end up in a *ZoomChange event anyways, and the only consumer already
listened for them.

We can reduce the size of the SSO by removing the element slot entirely, and instead retrieve the element through a callback function. The callback will take in the value in the private slot of the SSO, which is either a LoadedScript* (from the browser) or a JSObject* (from the shell). In addition, this removes the requirement of having a script dom element ready when parsing a JS script which can open up new opportunities for performance.

In Document::HasStorageAccess(), we try to get the top-level document.
To check if the document is first-party to the top-level document. But,
this won't work for Fission since the top-level document could be
out-of-process.
In this patch, we use broswing context to get the top-level principal to
test if the document is thrid-party. If we cannot get the top-level
outer window, the top-level document should be cross-origin. So, we know
the answer. If the top-level document is available, we check the
principal to see if the document is first-party.
