For now do the obvious check rather than bigger refactorings, since we keep them
matching :link or not depending on whether they have an href.
I'll file an HTML spec issue about not making them traversable, and a MathML
issue about the craziness that it is that almost all MathML elements can be
links.

We always define it to the same thing, and we're inconsistent in whether
we use `CPP_THROW_NEW` or `throw()`, so we might as well just use the
standard C++ thing and get rid of some baggage.

There are two existing callers of IsTableCellFrame that both appear to want to
include BCTableCell frames, but don't. A patch in bug 1547759 will add a
third that wants the same.
The existing users of frame types all have to work around it being a distinct
type, and none appear to want the distinction. This removes that complexity.
If any callers want to make the distinction, they could implement QueryFrame
for BCTableCellFrame and use it. (It's not implemented now, though!)
In a little more detail, prior to this patch (in my debug build, at least):
* nsQueryFrame::ClassID::nsMathMLmtdFrame_id was 46
* nsQueryFrame::ClassID::nsTableCellFrame_id was 47
* nsQueryFrame::ClassID::nsBCTableCellFrame_id was 65
and entries 46 and 47 in sLayoutFrameTypes were
mozilla::LayoutFrameType::TableCell while entry 65 was
mozilla::LayoutFrameType::BCTableCell.
With this patch:
* nsQueryFrame::ClassID::nsBCTableCellFrame_id is 40
* nsQueryFrame::ClassID::nsMathMLmtdFrame_id is 41
* nsQueryFrame::ClassID::nsTableCellFrame_id is 42
and entries 40 through 42 in sLayoutFrameTypes are
mozilla::LayoutFrameType::TableCell.

This fixes an edge case where it was possible for an HTMLMediaElement in the
middle of setup to have ownership transferred to a inactive document and deref a
null pointer. This happened because we have special handling for EME related
media where we perform more aggressive shutdown on for media in inactive
documents.
As far as I can tell, there's nothing specced that forbids performing EME
related functionality on elements in inactive documents. However, our code
already prevents doing so in other cases. E.g. if you create an inactive
document, place an HTMLMediaElement in it and try to setup EME related data on
it, then that will fail. So this fix just covers another such case.
While it would be nice to support doing these operations on inactive document's
media, it seems like very much an edge case, and something that would require a
large amount of reworking in how we handle inactive documents. We can cross that
bridge later should we ever need do so.

The time input widget was missing a call to updateEditAttributes which was
caught by the test, which can be seen without this patch by going to:
data:text/html,<input type="time" disabled value="20:40">
Toggling the 'disabled' attribute back and forth fixes the rendering.

Editor creates a `<br>` element to end of a block if last line
of the block is empty because caret should be placed as there is an empty
line. Such special `<br>` element has `type` attribute whose value is "_moz".
However, adding/removing the attribute is expensive and such hacky attribute
shouldn't be referred nor changed by web apps.
Therefore, this patch makes `HTMLBRElement` take another specific flag whether
it's a special node for empty last line. For making the meaning clearer,
this patch calls the such `<br>` elements as "padding `<br>` element for
empty last line" insead of "moz-br". So, this patch also includes a lot of
renaming methods and variables, and modifying related comments.
Note that with this change, `IMEContentObserver` counts the padding `<br>`
element in `<textarea>` because it's inserted before setting the new flag
and setting the flag does not cause DOM tree mutation. This issue will be
fixed by the following patches.

Editor creates a `<br>` element when it's root element is empty.
Then, it's stored by `TextEditRules::mBogusNode` and used for checking
whether the editor is empty quickly. However, this `<br>` element has
`mozeditorbogusnode` attribute whose value is `true`. However, adding or
removing the attribute is not cheap and web apps can refer such illegal
attribute.
Therefore, this patch makes `HTMLBRElement` take a specific flag whether
it's a bogus node or not. However, this means that this hacky thing will be
exposed outside editor module. For making what is the bogus node clearer,
this patch calls the such `<br>` elements as "padding `<br>` element for
empty editor". So, this patch also includes a lot of renaming methods and
variables, and modifying related comments.

This is inherently large, because modifying these bits of DOMMediaStream and
MediaStreamTrack affects all consumers and producers of all DOMMediaStreams and
MediaStreamTracks.
Things are generally much simpler now.
Producers of tracks now create a MediaStream in the graph, add it to a
MediaStreamTrackSource subclass that takes ownership of it, and add the source
to a MediaStreamTrack. Should the producer need a DOMMediaStream it is now much
simpler to create as the only thing needed is the current window. The stream is
a rather simple wrapper around an array of MediaStreamTracks.
HTMLMediaElement is still not as straight forward as other consumers since it
consumes the DOMMediaStream directly, as opposed to a set of tracks.
The new MediaStreamRenderer helper class helps bridge the gap between this fact
and the new track-based MediaStreamGraph interface, as it needs to juggle
registering multiple audio tracks for audio output. This hooks into existing
HTMLMediaElement logic and brings a welcome simplification to all the glue
previously needed there.

See https://github.com/whatwg/html/issues/4810.
I accidentally changed its behavior in bug 1547985 due to an embarrassing typo.
Turns out that my typo made us follow the spec, but the spec is not what we or
anybody else implemented. Fun times. I added a test accounting for the proposed
spec change.
There's a different divergence between what does abscenter map to. Other
browsers don't map `abscenter` at all, looks like, but it's in the spec.
We may want to remove it, but for now I've left it in the test.

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

So for exmaple, if there are two viewport meta tags like this;
<meta name="viewport" content="width=980">
<meta name="viewport" content="initial-scale=1,maximum-scale=1">
We will use "initial-scale=1,maximum-scale=1". Before this change we used to
use merged "width=980,initial-scale=1,maximum-scale=1".
Another example is to replace the content of a single viewport meta tag like this;
<meta id="viewport" name="viewport" content="width=device-width, initial-scale=1">
what will happen when this tag is replaced by below;
<meta id="viewport" name="viewport" content="width=1080">
We will use the replacing one (i.e. "width=1080"), before this change, we used
to use merged "width=1080,initial-scale=1".
As of this commit, we don't properly remove corresponding viewport meta data
when a) viewport meta tag is detached from document and b) `name` attribute is
changed from 'viewport'. These cases will be handled in subsequent commits.
Note that we no longer store invididual viewport meta data in Document::mHeaderData
so that nsIDOMWindowUtils.getDocumentMetadata doesn't work any more for the
invididual viewport meta data, but there is no use cases for them other than
two test cases which are removed in this commit.

My preference was to annotate most of the failing tests with `fail-if` so that
if they start passing, the `fail-if` needs to be removed and they need to keep
passing. That doesn't work for tests that timeout, or which trigger failures
from their cleanup functions, however, so those tests need skip-if. And tests
with fail in their cleanup functions likely leave the browser in an
inconsistent state for subsequent tests, anyway, so really should be skipped
regardless.
There are some remaining tests which still fail because of crashes. I chose
not to skip them here, but to fix the crashes in separate bugs instead.
