There are a ton of places that would need to be changed, many of which
will be changing soon anyway with the non-webextensions change in 57
so this is mostly the expedient route to keeping the tree green.

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.

Previously the harness would check for navigator.plugins[Test Plug-in] in the browser window, but that is now blocked from working. Instead we can simply use an existing getTestPlugin function that enumerates the plugin through nsIPluginHost

To mitigate the delay that a new content process startup might cause, when the
browser reaches a non-busy state we attempt to prelaunch an empty content process
in the background that can be grabbed and used the next time we need one. This patch
enables the preallocated process manager by default and attempts to fix all the
issues that prevented us doing this sooner.
That function has a special path for when there's no parent reflow input, and if
there's a parent reflow input there should always be a parent frame.

By passing the startTime as a TimeDuration we are able to represent times in the
distant past (and with the same range as we can represent on the main thread so
that if we do encounter range errors in future, they should not differ between
the main thread and the compositor).
This patch includes a crashtest. I have verified that, without the code changes
included in this patch, this crashtest fails on debug builds on OSX.

We want to see if we can drop support due to web pages not using it.
Edge and Safari already don't support it, and Chrome reports that usage
is low enough that they're willing to drop it. But telemetry doesn't
tell us about web usage if we're triggering it via our own internal
code.

scrollbars.css is the only sheet which is parsed as author level, but later
added as agent level in [1]. Add a new enum value so that it can be parsed
as author level in gecko (nsCSSParser::AgentRulesEnabled() will exclude it),
but servo can recognize it as agent level sheet when the sheet is created.
Delete UserRulesEnabled() because no one uses it.

This patch shouldn't affect behavior -- it just takes a latent opportunity for
simplification and removes an unused layer of indirection. These functions were
set up to look like they took outparams, but none of the callers were using the
value left in the outparam.

The call that's causing the crash seems to be [1], that is, we're trying to
recreate frames for the root element, which should always have a frame created
at the initialization of the PresShell.
So the function I removed in that bug had something like the following:
if (!mDidInitialize) {
// Nothing to do here. In fact, if we proceed and aContent is the
// root we will crash.
return NS_OK;
}
Which PostRecreateFramesFor doesn't guard against (because I thought it was not
needed, per tryserver results).
Sounds a lot like we do need that check, though I'd like to have a testcase
where it happens :(

Here we add a new UserFontLoadState value, STATUS_LOAD_PENDING, which
represents the state just after a gfxUserFontEntry's url()-valued source
would being loading, except that we can't start the load due to being
on a Servo style worker thread. In that case, we defer the work of
initiating the load until just after the Servo traversal is finished.
URLs that can normally be loaded synchronously, such as data: URLs
and script-implemented protocols marked as synchronous, must be
handled asynchronously when encountered during Servo traversal, since
various main-thread only work (in FontFaceSet::SyncLoadFontData) must
happen. This is a user visible change from stock Gecko, but should
only happen when font metrics for a data: URL font are requested
due to ch/ex unit resolution when layout hasn't previously requested
the font load. Hopefully nobody relies on synchronous resolution of
ch/ex units with data: URLs.
We unfortunately also can't pick gfxUserFontEntry objects out of the
UserFontCache during Servo traversal, since validating the cache
entry involves doing content policy checking, which is not thread-safe
(due in part to taking strong references to nsIPrincipals).
Platform fonts and ArrayBuffer-backed DOM FontFace objects continue
to be handled synchronously.
The PostTraversalTask does not take a strong reference to the
gfxUserFontEntry object, since it is held on to by the DOM FontFace
object, which itself won't go away before the PostTraversalTask
is run.

In a later patch, we'll want to queue up some tasks to run when the
Servo traversal is one, and the ServoStyleSet seems like the natural
place to store those tasks. We could probably find the ServoStyleSet
by chasing a bunch of pointers from the task-adding call sites, but
it seems simpler just to make it available directly.
