I've tried hard to find a solution for the clipped window button problem which
does not involve swizzling but could not find one.
The officially ratified ways of moving the window buttons are:
1. Use an NSToolbar in your window, or
2. Make a custom window with your own buttons.
I don't think having an NSToolbar is an option for us. And making our own window frame
implementation would be hard to get right and can easily behave differently from the
native implementation.
I've also tried asking the window to not render any window buttons on its own; then we
could make our own buttons and place them on top of our view. But if I change the
window's styleMask to be just NSTitledWindowMask, it doesn't only make the buttons
disappear, it also makes the window non-resizable. And if I include NSResizableWindowMask,
the buttons come back (only the zoom button is enabled, the other two are grayed out).
This change also stops overriding _wantsFloatingTitlebar when CoreAnimation is
enabled, which is necessary for the window buttons to render.

This gives us two behaviors for free which we were achieving through manual
overrides:
- The content view is sized to cover the entire window frame.
- The window controls are placed on top of the content view (instead of
underneath it in z-order).
It also forces CoreAnimation layers for the window's entire NSView hierarchy, so
we only use it when the CoreAnimation pref is enabled.
NSFullSizeContentViewWindowMask is only available on 10.10 and up, but we still
support 10.9, so we cannot remove the code with the manual overrides just yet.
This change also requires a change to NonDraggableView in order to preserve
window dragging behavior in the titlebar: When NSFullSizeContentViewWindowMask
is used, the method which assembles the window's draggable region takes a
different path. It treats the titlebar specially, and traverses the NSView
hierarchy twice, once for the titlebar area and once for the rest of the window.
Outside the titlebar, it calls _opaqueRect on every visible NSView, but for the
titlebar area, it calls _opaqueRectForWindowMoveWhenInTitlebar instead.
Overriding _opaqueRectForWindowMoveWhenInTitlebar allows us to achieve the old
dragging behavior.

This makes them only apply in windows with titlebars, which is the only place
where they're needed. The setContentView override can even cause harm for other
windows, such as sheet windows, because it'll move the content view below a
full-window covering solid grey view provided by the system, in builds that
link against the 10.14 SDK and don't override _wantsFloatingTitlebar.

It looks like a big patch but it's mostly just moved code, with some duplication:
- Layer creation and destruction moves to LayerManagerComposite and RendererOGL.
- BasicCompositor IOSurface setup code moves to BasicCompositor.cpp.
- OpenGL IOSurface setup code moves to CompositorOGL and RenderCompositorOGL.
The duplication is a bit unfortunate but the LayerManagerComposite code will
diverge from the WebRender code soon.
BeginFrame gets a new argument aNativeLayer. This argument will go away again
over the course of this patch queue. But for now, BeginFrame is the best place
to do the layer setup because it's a very close place to PreRender which is
where that code was previously.
I wasn't able to think of a nice way to give CompositorOGL and BasicCompositor
platform-specific behavior without #ifdefs. So now LayerManagerComposite uses
the "cross-platform" NativeLayer interface, but CompositorOGL and
BasicCompositor use NativeLayerCA because they actually need the IOSurface, and
they do that in #ifdef'd code.
Luckily, NativeLayerCA.h can be included in both .cpp files and in .mm files.

The source of the trouble is our setContents override, which makes sure the window's
content view is the bottommost view in the window, and its interaction with a change
in behavior on 10.14, where windows that return YES from _wantsFloatingTitlebar will
contain an additional NSView for the window background. Our setContents override
moves the content view behind that window background view, which covers it with a
solid gray color.

updateLayer expects some objects to be non-null which are only initialized when the pref is set.
But in builds that were compiled with the 10.14 SDK, all NSViews are layer-backed by default, so
wantspdateLayer gets called, and returning YES from that unconditionally will cause updateLayer

Without this, in windows with title bars, such as the bookmark library window,
the title bar and the content would update at different times.
The title bar paint is done as part of a main thread CoreAnimation transaction.
However, by default, we don't get notified of all main thread CA transactions;
our only notification mechanism is the updateLayer handler on the PixelHostingView,
and that handler is only invoked (the layer is only displayed) if the layer has
been marked as needing display. And by default, window focus changes do not mark
random views' backing layers as needing display. Usually, what this means is that
the window will be painted twice: Once in the main thread transaction, and then
another time on the compositor thread once Gecko has noticed a state change and
triggered its own composite in response. (Often, Gecko's compositor-side paint
will actually happen *before* the main thread paint, because the main thread is
often busy with repainting the system menu bar during window focus changes.)
Such non-atomic window repaints look glitchy.
Calling SuspendAsyncCATransactions will result in a call to updateLayer in the
upcoming CoreAnimation transaction and lets us update the entire window in one
atomic paint, and it will avoid updating the window early if the compositor
thread gets ahead of the main thread.

Window overlay drawing was added as a workaround for the following:
When our NSOpenGLContext covered the entire window, it would cover the titlebar
contents and hide the window buttons and the title string. It would also not
get anti-aliased rounded corner clipping.
In windows that use CoreAnimation layers for the window frame, this is no longer
a problem, because the CoreAnimation layer tree takes care of these effects:
It applies rounded corner clipping to the window content layers, it puts the
window buttons on top, and it also puts the title string on top if it is shown.
So when we're using CoreAnimation, the existing code needs to be deactivated,
otherwise we'd draw those things twice.

This makes context menus work. Regular windows are still blank at this point.
This introduces a visual regression on 10.9: context menus and panels now no
longer have a shadow. Only 10.10 and above support shadows on transparent windows
that use CoreAnimation; 10.9 is not able to obtain the shadow shape on those
types of windows.
I think this is an acceptable regression to take. We want to use CoreAnimation
for all window types because it simplifies the code (no need to handle two
paths) and because it avoids expensive mode switches if we realize too late
that a window we just opened is supposed to use CoreAnimation.

This patch also causes all windows (including context menus, tooltips, arrow

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.

Currently it's completely unclear at use sites that the getters for `once`
static prefs return the pref value from startup, rather than the current pref
value. (Bugs have been caused by this.) This commit improves things by changing
the getter name to make it clear that the pref value obtained is from startup.
This required changing things within libpref so it distinguishes between the
"base id" (`foo_bar`) and the "full id" (`foo_bar` or
`foo_bar_DoNotUseDirectly` or `foo_bar_AtStartup` or
`foo_bar_AtStartup_DoNotUseDirectly`; the name used depends on the `mirror` and
`do_not_use_directly` values in the YAML definition.) The "full id" is used in
most places, while the "base id" is used for the `GetPrefName_*` and
`GetPrefDefault_*` functions.
(This is a nice demonstration of the benefits of the YAML file, BTW. Making
this change with the old code would have involved adding an entry to every
single pref in StaticPrefList.h.)
The patch also rejigs the comment at the top of StaticPrefList.yaml, to clarify
some things.
