Before this patch, PSM would register content type handlers to handle certain
certificate types. This was an easy way to install a client certificate after
generating a key with <keygen>, but keygen has been removed. This was also an
easy way to install root certificates, but that's actually a considerable
security risk. We kept this functionality for so long because it was the only
way to add a 3rd-party root certificate to Fennec's certificate store. Now that
Fennec is EOL, we can remove it. (Fenix will need a way to trust 3rd party root
certificates, but the path forward there is to implement the enterprise roots
feature for Android.)

For Win32k lockdown, we need to remove the content processes' ability to
call GetICMProfileW(). Since it needs this to retrieve the output color
profile, a new synchronous call is added that allows it to request the
parent process to read this file on its behalf.
The contents of the file are now being cached as well, as this should help
ease some of the increased parent process I/O caused by the children not
being able to do this in their process anymore.

WalkHistoryEntries function gets called by nsSHistory::CloneAndReplaceChild
and nsSHistory::SetChildHistoryEntry recursively, so those have to be moved
into the parent process. This eliminates many sync IPC calls.
To facilitate transition to a new session history design,
we are mirroring mOSHE and mLSHE SH entries from docshell to browsing context.
Whenever we update those entries in docshell, we will also update those in BC,
and vice versa.

We want to be able to send IPC messages from the translation in the parent. So
the simplest thing it move the top level actor parts of CanvasParent into
CanvasTranslator.
This patch also moves the canvas thread management parts out into a new
CanvasThreadHolder class and hopefully makes the lifecycle management of these
much more robust. This includes the use of a TaskQueue per CanvasTranslator to
manage serial processing on the canvas workers, instead of a boolean.

The default method implementations cause problems when trying to
override them with different types in a direct call class.
For the `Recv__delete__` case there's a simple solution: omit it if
there are any arguments, because it doesn't make much sense to specify
arguments and then completely ignore them, and the no-arg case isn't a
problem for overriding.

This change adds new "remote backbuffer" logic when compositing without
HW acceleration on Windows (IE compositing through Cairo using the Win32
GDI)
A new piece of shared memory is created between the GPU process and the UI
process, and the GPU process sends requests to the UI process to first "borrow"
a properly-sized buffer to draw into, and then sends a "present" request to
tell the UI process to actually blit the buffer to the Win32 window.
This is needed for the GPU sandbox to work, since Windows rightly doesn't
allow the untrusted GPU process to directly draw the contents of a window
owned by the trusted UI process.

Splits WebGLContext into ClientWebGLContext and HostWebGLContext. The Client enables the JS-control of a WebGL context in a content procecss while the Host executes the WebGL graphics operations (via a WebGLContext that maintains much of the existing code) in the compositor process. At this point, the cross-process behavior is disabled -- this series of patches is an incremental step toward that final goal.

Previously, we created TextureD3D11 objects in the content process to back surfaces created for the plugin process. Those objects were then composited by the async ImageBridge. In order to remove Win32 kernel operations from content (including DX/GDI operations), this patch bounces the requests from content to the compositor process. The compositor process maintains 2 textures to be used for all plugin composition -- one for the plugin process and one for display. The plugin process can freely write to its texture and request composition when it is done, which triggers a blit to the display texture. This mirrors pre-existing behavior.

These operations report whether certain async plugin drawing modes are supported on the host architecture. They use kernel graphics operations to decide this so they need to be removed from the content process for sandboxing. We just bounce the requests to the gpu process (or main process on systems without a GPU process).
