Again, always initialized before use, and debug-only in any case, but worth
doing I think.

Not all of them are initialized/used in all the paths, but worth doing it just
for sanity.

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.

Per description in bug 1361072, this is the standard idiom to assign
outparam pointers of refcounted types.

Continue to allow non-multiprocessCompatible extensions in automation.
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.

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 :(
