When we shutdown the browser while the GMPService is active we can end up
leaking a GMPParent, GeckoMediaPluginServiceParent, and a Runnable. I tracked
this down to the runnable dispatched to the GMP thread in
GMPParent::ChildTerminated(). The dispatch of this runnable is failing as we
are dispatching the runnable to a reference of the GMP thread which we have
previously acquired, but that thread is now shutdown. So the dispatch fails,
and if you look in nsThread::DispatchInternal() you'll see that we deliberately
leak the runnable if dispatch fails! The runnable leaking means that the
references it holds to the GMPParent and the GMP service parent leak.
The solution in this patch is to not cache a reference to the GMP thread on the
GMPParent; instead we re-request the GMP thread from the GMPService when we
want it. This means that in the case where the browser is shutting down,
GMPParent::GMPThread() will return null, and we'll not leak the runnable. We'll
then follow the (hacky) shutdown path added in bug 1163239.
We also need to change GMPParent::GMPThread() and GMPContentParent::GMPThread()
to return a reference to the GMP thread with a refcount held on it, in order
to ensure we don't race with the GMP service shutting down the GMP thread
while we're trying to dispatch to in on shutdown.

We should let window decide whether resume the media component, not document.
Because we might have media component which is not in DOM tree, but we still
want to play it.
Window should be resumed when all following conditions are true,
(1) the tab is in the foreground
(2) there is any alive media component (MediaElement/WebAudio/PlugIn...)
(3) the window is blocked (nsISuspendedTypes::SUSPENDED_BLOCK)

We often need to turn on both MediaSample and MediaDecoder logs when debugging sample activities.
So it is convenient to merge them into a single log module.
Use `MOZ_LOG=MediaDecoder:4` to show decoder logs.
use `MOZ_LOG=MediaDecoder:5` to show both decoder and sample logs.

shmems just so we can get this working. Once this is working, I'll follow up

The MediaKeys accesses the ChromiumCDMProxy on the main thread. But the
ChromiumCDMVideoDecoder will need to access the ChromiumCDMProxy on the decode
task queue in order to get a reference to the ChromiumCDMParent so that it can
talk to the CDM (on the GMP thread).
Additionally we'll need to shutdown the ChromiumCDMProxy, and if we do that
on the main threrad while the ChromiumCDMVideoDecoder is trying to get the
ChromiumCDMParent reference, we could hit thread safety issues.
So we need to hold a lock while reading or writing from the ChromiumCDMProxy's
reference to the ChromiumCDMParent. So add a GetCDMParent() function to the
ChromiumCDMProxy which takes the lock while reading or writing the reference.
This means that the caller will always get a valid reference. There is no guarantee
that the ChromiumCDMParent isn't shutdown after the reference is taken; if that
happens, the ChromiumCDMParent returned will fail on all operations.
In a later patch in this series, the ChromiumCDMProxy will anull its reference
to the ChromiumCDMParent on shutdown, and cause GetCDMParent to return null.
So callers need to null check the return value of GetCDMParent.

This commit refactors the SetDomain method in a Document to call a new function
IsRegistrableDomainSuffixOfOrEqualTo(), defined in HTML [1]. This commit tries
not to rename anything except input variables, so as to remain as clear as
possible. It likely should have various variables renamed, but given the
author's unfamiliarity with this module, review seems a good time to do that.
It's also duplicating comments a little bit; let me know which one(s) you'd like
to keep!
Note: Commentary on the HTML change is available in the PR [2], and the
rationale for this behavior in Web Auentication, where this algorithm will be
used, is also recorded [3].
Update 1: Refactored two new protected methods to avoid code duplication.
Update 2: Bugfix: Be sure to use CreateInheritingURIForHost for the
provided domain so as to catch internationalized domains.
Update 3: Nit-fix and rebase

Under some circumstances, and seen on Windows 8, a decoded sample can be returned without the MFT returning MF_E_TRANSFORM_STREAM_CHANGE.
For historical reasons, we required that message to be returned at least once to set the output image size. This was required as the decoder used to be recycled with different video streams.
This is no longer the case, we can rely on the video info instead. It also greatly simplifies the code

This mMediaTracksConstructed flag should belong to a MediaDecoder,
every time a HTMLMediaElement switches its MediaDecoder, the flag should be reset to false again.
So, we move the mMediaTracksConstructed flag back to MediaDecoder, by this way,
HTMLMediaElement provides only the mechanism to construct and remove media tracks,
and MediaDecoder uses the flag, mMediaTracksConstructed, to provide policy.

This patch changes the crashreporter client code as well as the crash service
code to compute a SHA256 hash of a crash' minidump file and add it to the
crash ping. The crash service code computes the hash on the fly before handing
over the crash to the crash manager; the crash manager will then add it to the
crash ping. The crashreporter client on the other hand sends the hash via the
ping it generates but it also adds it to the event file so that the crash
manager can pick it up and send it along with its own crash ping. On Fennec
the crashreporter activity takes care of computing the hash.
SHA256 hash computation uses nsICryptoHash in the crash service, the
java.security.MessageDigest class in Fennec, the bundled NSS library in the
crashreporter when running on Windows and Mac and the system-provided NSS
library under Linux. The latter is required because the crashreporter client
uses the system curl library which is linked to NSS and which would thus clash
with the bundled one if used together.
This patch introduces two new methods for the nsICrashService interface:
|getMinidumpForID()| and |getExtraFileForID()|, these reliably retrieve the
.dmp and .extra files associated with a crash and ensure the files exist
before returning. These new methods are used in the CrashService for
processing and will become the only way to reliably retrieve those files
from a crash ID.

This is a bug from https://hg.mozilla.org/mozilla-central/rev/2d171d75b746 (bug 1157546). It took a shortcut in trying to get around one of the downsides of tracking visibility on frames instead of content nodes.
We cannot get our primary frame during FrameCreate calls because FrameCreate is called during the frame's Init() function, which happens before the primary frame pointer is set.
So when TrackImage is called from FrameCreate |frame| will be null but mFrameCreateCalled will be true. So we won't hit the early return that tries to detect nonvisible images.
The comment being removed is just wrong. We can obtain a frame for <feImage> just as well as any other image type.
The thing that is different about <feImage> is that it calls IncApproximateVisibleCount() followed by FrameCreated() in the frame's Init() function. This means that the frame is marked visible at the time of the FrameCreated, and there will be no further calls to TrackImage (because there are no further changes). So the FrameCreated call is the last chance to mark this image visible. The regressing changeset tries to get around this by just considering the image visible whenever we know a frame exists (because of mFrameCreateCalled) but can't access it. This ends up affecting all types of images, not just <feImage>.
The above paragraph is also true for SVG <image> that are non-display.
This property allows enumerating over all permissions. As the content
process no longer has access to all permissions, this method cannot be
correctly implemented in the content process anymore.
Because of that, we now error with NS_ERROR_NOT_AVALIABLE when it is
accessed in the content process.

Our caller is C++ code, and the implementations are all also written in C++,
so there is no reason to go through SpiderMonkey here. This patch also makes
nsILoadContext builtinclass to ensure that the implementation is always native.
nsStyleContext::CalcDifference had an optimization where, when we knew
that the old and new style context have the same rule node, we knew that
the only change hints that would need to be handled are those in the
"not handled for descendants" category, generated due to explicit
'inherit' values on reset properties. This was because any changes due
to differences in inherited properties should only have generated
"handled for descendants" change hints (and thus would already have been
handled on an ancestor).
Before bug 931668, this let us avoid calling CalcDifference on structs
that only would have generated hints that we knew we already would have
handled. However, after bug 931668, we compare all structs anyway so
that we can set the aEqualStructs outparam, so we don't gain anything
from this optimization. We can still return these change hints we know
will not need to be handled, and rely on ElementRestyler::CaptureChange
to filter them out.
