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.

The change in browser_net_view-source-debugger.js is needed because we now use WebIDL callbacks for MessageListener, and they add async creation stack frames.
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.

When ContentChild::RecvInitRendering is received, it tries to setup the
IPDL actors related to rendering. If the GPU process crashes before or
during this process, it will fail, and cause the content process to
crash as well. This is unnecessary because the UI process will either
restart the GPU process, or subsume its job into itself, and trigger
ContentChild::RecvReinitRendering. It is a similar case for failures in
ContentChild::RecvReinitRendering.
Since the GPU process crashing should be a recoverable scenario, we now
check if the remote IPDL actor is in the UI or the GPU process. If it is
in the UI process, it will fail/crash as it does today. If it is in the
GPU process, it will wait for the next
ContentChild::RecvReinitRendering.
For failures that are not IPDL related (e.g. failed to get some resource
like spawning a thread), we release assert specifically for those
failures. They are not recoverable.
nsIDOMWindowUtils::sendKeyEvent() is already replaced with nsITextInputProcessor
for making callers set any attributes of KeyboardEvent and guaranteeing
consistency behavior with keyboard events caused by native key events. E.g.,
whether keypress event should be dispatched or not is automatically decided.
nsIFrameLoader::sendCrossProcessKeyEvent() is similart to
nsIDOMWindowUtils::sendKeyEvent() but it dispatches keyboard events in
child process directly. Currently, nsITextInputProcessor doesn't have this
feature but nobody wants/uses this feature. So, for removing actual
implementation of nsIDOMWindowUtils::sendKeyEvent(), i.e.,
nsContentUtils::SendKeyEvent(), which is shared by both
nsDOMWindowUtils::SendKeyEvent() and nsFrameLoader::SendCrossProcessKeyEvent(),
we should remove this unused API too. (FYI: it's implemented for old Fennec,
by bug 553149.)

Calling GetPresShell() might create a content viewer, which might cause
script to run. This is bad if there's a ForcePaint message queued up,
because it could mean running the force painting code while we're still
in the midst of making a tab hidden, which would put us in an inconsistent
state.

This assumption also mirrors how non-remote browsers have their docShells active by default.
In order to do this, I also have to increase the initial epoch's for the TabParent and TabChild,
as if a RenderLayers has been called. Originally, since the epochs initted at 0, and the epochs
stored by the [Layer|WebRender]TransactionParent were also initted at 0, we'd hit this branch:
https://searchfox.org/mozilla-central/rev/c633ffa4c4611f202ca11270dcddb7b29edddff8/gfx/layers/ipc/LayerTransactionParent.cpp#703
and then we'd never alert the TabParent about the layer upload.

Originally, setting the active state on the DocShell for remote browsers also did the
work of making the TabChild render its layers and upload them to the compositor.
This patch adds a new renderLayers method to nsITabParent which allows more fine-grained
control - we can now, for example, cause layers to be rendered and uploaded without
activating the DocShell.
Note that if one activates or deactivates the DocShell, we'll still do the work of
attempting to render / clear the layers if it hasn't already been done.

The property in question is the offset from the content process to the
chrome process, but it gets called various things for historical
reasons. Let's be consistent and just call it the chrome offset
everywhere.
Also, in some places this was needlessly getting turned into a
nsIntPoint via ToUnknownPoint(), only to be turned back into a
LayoutDeviceIntPoint at all the use sites. So this patch also updates
some function signatures to avoid the needless conversion.
No functional changes.
