Bug 1641361 - [wpt-sync] Update web-platform-tests to cbfde04695a79256d42991513c83a7b97dc14fcd, a=testonly

Automatic update from web-platform-tests
[wpt] Fix css-contain "replaced" tests.

These tests were inadvertently testing our UA stylesheet for the audio
element. In our UA stylesheet we have:
audio {
  width: Xpx;
  height: Ypx;
}

which means that the intrinsic size tests are failing. This fixes the
tests to change the width/height when appropriate to "auto".

There is probably a discussion which needs to be had about the UA style
for the audio element, but not today.

[EventTiming] Use polling in performance.eventCounts test

It looks like actions.send() does not wait for the events to get
processed in order to resolve the promise, which means eventCounts may
not be populated by the time we begin testing it. Hence, in this CL we
perform a polling-based approach. Sample failure:

Automatic update from web-platform-tests
Load pending resources after style adjustments.

We don't fetch resources for ComputedStyle which is in a display:none
subtree or display:contents since [1]. Style adjustments are done to the
display type in the StyleAdjuster and we need to make sure we load
resources where display changes from a non-rendered value to a rendered
one after style adjustments.

Specifically, this happens with blockification of :root elements which
are display:contents.

Bug 1633866 - [taskgraph] Create a system to choose how test manifests are loaded via a parameter, r=tomprince

Currently test manifests are loaded by instantiating a TestResolver and
traversing moz.build files to find manifests.

With 'manifest-scheduling', we'll want to grab the manifests directly from the
bugbug service instead. Initially we'll want to enable manifest-scheduling with
|mach try auto|, but not on autoland yet.

This patch will allow |mach try auto| to set the parameter that causes bugbug
to be used (see future commits in this bug).

We create sub images from larger images by using a stride that matches
the original and adjusting the offset. This creates a situation where
the last row will only have stride - offset bytes. This stops us
from lying to CGDataProvider.

Initially, IPCInternal{Request,Response} had contained IPCStreams which would
result in unecessary copying when sending the objects over IPC. The patch
makes these streams either:

1) ParentToParentStream (just a UUID)
2) ParentToChildStream (a PIPCBlobInputStream actor, acting as a handle)
3) ChildToParentStream (a real IPCStream)

These three types are union-ed together by the BodyStreamVariant IPDL structure.
This structure replaces the IPCStream members in IPCInternal{Request,Response}
so that, depending on the particular IPDL protocol, we can avoid cloning streams
and just pass handles/IDs instead.

As a side effect, this makes file-backed Response objects cloneable. Initially,
these Responses would be backed by an nsFileInputStream, which is not cloneable
outside the parent process. They are now backed by IPCBlobInputStreams, which
are cloneable.

One thing that's not really satisfactory (IMO), is the manual management of
IPCBlobInputStreamStorage so that no streams are leaked, e.g. if we store a
stream in the IPCBlobInputStreamStorage but fail to send an IPC message and
therefore fail to remove the stream from storage on the other side of the IPC
boundary (only parent-to-parent in this case).

Bug 1639313 - Print usage if you call a bare `mach vendor`, `mach cargo`, or `mach remote` r=remote-protocol-reviewers,froydnj,whimboo

The architecture of `mach` does not make this easy to do from within one process, not least of all due to persistent global, mutable state. :( There may be another way to do this, I'm not saying it's completely impossible (and obviously with a significant enough refactor there's a way to make this happen), but subprocessing is a foolproof way to accomplish the same.
