Makes transfer of samples between the content and CDM processes use shmems.
The Chromium CDM API requires us to implement a synchronous interface to supply
buffers to the CDM for it to write decrypted samples into. We want our buffers
to be backed by shmems, in order to reduce the overhead of transferring decoded
frames. However due to sandboxing restrictions, the CDM process cannot allocate
shmems itself. We don't want to be doing synchronous IPC to request shmems
from the content process, nor do we want to have to do intr IPC or make async
IPC conform to the sync allocation interface. So instead we have the content
process pre-allocate a set of shmems and give them to the CDM process in
advance of them being needed.
When the CDM needs to allocate a buffer for storing a decrypted sample, the CDM
host gives it one of these shmems' buffers. When this is sent back to the
content process, we copy the result out (uploading to a GPU surface for video
frames), and send the shmem back to the CDM process so it can reuse it.
We predict the size of buffer the CDM will allocate, and prepopulate the CDM's
list of shmems with shmems of at least that size, plus a bit of padding for
safety. We pad frames out to be the next multiple of 16, as we've seen some
decoders do that.
Normally the CDM won't allocate more than one buffer at once, but we've seen
cases where it allocates two buffers, returns one and holds onto the other. So
the minimum number of shmems we give to the CDM must be at least two, and the
default is three for safety.

This means we can pass anything that converts implicitly to a Span to
PostResult, including an nsTArray<uint8_t>. We can also pass a Span
that contains the contents of a Shmem's buffer.

In the new architecture of Quantum DOM, all timer callback need a
specified event target. So, we add the new document arg to Start
function to get the event target from it. And update all callers.

In the new architecture of Quantum DOM, all runnables need a name label.
So, we add the new string-label arg to Start function, and update all
callers.

Since the ::cue div created by JS, it doesn't have the NODE_IS_NATIVE_ANONYMOUS flag.
We set the NODE_IS_NATIVE_ANONYMOUS when binding to domtree from the ::cue up to the RootOfAnonymousSubtree
so that GetClosestNonNativeAnonymousAncestor will return video element as style parent.

This seems like an existing bug. If the content specifies
attributeType="yer:opacity", we should not try to animate it as a CSS property.
This patch adds a namespace check before we try to animate as a CSS property.

In bug 1315874 we will create a method to check if we're likely to need to
resolve base styles or not, and for that we need to extract the check for
whether or not we're animating a CSS property.

nsSMILCompositor::mCachedBaseValue is an nsAutoPtr<nsSMILValue> that we allocate
on the heap. It looks like we did that back in bug 533291 presumably because it
makes transferring these cached values between nsSMILCompositor objects cheaper.
One drawback of this, however, is that mCachedBaseValue has two null states:
the mCachedBaseValue pointer can be null, and the pointed-to nsSMILValue can be
a null value (i.e. IsNull() returns true).
Now that we have move ctors and operators defined for nsSMILValue we can
transfer these objects between compositors cheaply without requiring the object
to be allocated as separate heap object. This patch makes mCachedBaseValue just
a regular nsSMILValue class member (i.e. drops the nsAutoPtr).
There's a subtle difference in behavior with regards to the first sample.
Previously we would compare the (initially) null mCachedBaseValue pointer with
the passed-in nsSMILValue and set mForceCompositing to true. With this patch,
however, we will only set mForceCompositing to true if the passed-in
mCachedBaseValue is not null.
I believe this is correct, however, since if we don't call GetBaseValue in
ComposeAttribute we should not be setting mForceCompositing to true (something
else should ensure that gets set to true), and if we do call GetBaseValue the
result should not be a null nsSMILValue (except in some OOM cases where we don't
really care if we miss a sample). This patch adds an assertion to check that
GetBaseValue does, in fact, return a non-null value. (I checked the code and
this appears to be the case. Even in error cases we typically return an empty
nsSMILValue of a non-null type. For example, the early return in
nsSMILCSSProperty::GetBaseValue() does this.)

We will add to these includes later in this patch series so we sort them now so
it's clear where to add to.

Some interface tests into mochitest is failure on android beta and release.
test_serviceworker_interfaces.js has nonReleaseAndroid flag, so we should use it into test_interfaces.js and test_worker_interfaces.js

Before this change, if you did formatBlock on "a<span
contenteditable=false>b</span>c", it would become "acb", because the "a"
and "c" would be moved to the front of the node, and the "b" would be
left alone at the end because the editing code doesn't want to move it.
Now we will move the "b" as well, even though it's not editable, so that
the node remains "abc". The rule is that a non-editable element cannot
have its attributes or children changed, but it can have its parent
changed, so there's nothing wrong with moving it here.
On the way, I fixed an exception in insert*List if there was an
uneditable inline node around. I don't intend to fix all the todo's in
the test, but now it should have better coverage, at least.
