- Implemented WebVTTLoadListener to manage the webvtt parser.
- TextTrackCue now handles the conversion of webvtt nodes to
anonymous content which will be displayed on the video div
overlay.
- HTMLTrackElement manages the lifetime of the WebVTTLoadListener.
It's a little unfortunate that we need both ${jsvalHandle} and
${jsvalRef}, but the only other option is to consistently have a
MutableHandle in this code. If the thing we have to work with is a
Rooted, that means doing JS::MutableHandle<JS::Value>(&myRooted) as
the thing to substitute for ${jsvalHandle}. Just using "&myRooted"
doesn't work, because things like "&myRooted.set()" or
"&myRooted.address()" fail, even if parenthesized as
"(&myRooted).set()", because &myRooted is actually a Rooted*, not a
MutableHandle.
We could go the JS::MutableHandle<JS::Value>(&myRooted) route if
desired; it would primarily uglify dictionary and sequence to-js
conversions. With the setup in this patch, ideally it looks pretty
idiomatic except for the use of .set() instead of operator= on Rooted.
The code in nsHTMLStyleSheet implements LangRule to map xml:lang into
style and the code to manage its uniqueness.
The change to nsGenericHTMLElement fixes the mapping of the HTML lang
attribute to do cascading the way all other rule mapping does so that
the cascading works correctly.
The tests test that the correct style language is used for hyphenation
by copying over a set of hyphenation reftests that check its basic
response to languages. There are no specific tests for font selection,
but font selection is known to use the same language data from style.
I verified manually (see other attachments to bug) that the rule
uniqueness is being managed correctly.

Add webidl interfaces and implementations of the HTML <track>
element and related TextTrack, TextTrackList, TextTrackCue,
and TextTrackCueList dom objects.
Visibility is controlled by the media.webvtt.enabled pref,
which defaults to false.
HTMLMediaElement:NewURIFromString() is hoisted to
nsGenericHTMLElement so it's available to the track
element as well.
This patch is primarily work by Dale Karp, David Humphrey
and others as Seneca College.
There are still a handful that either are used with other runtimes, or that
happen very early/late in cx the lifetime of various things where it doesn't
necessarily make sense to have a cx on the stack. This should definitely ensure
that we're not doing double-duty with the nsCxPusher change, though.
