It's possible that if the HTMLMediaElement is loading while we're loading a new
document into a docshell, that the HTMLMediaElement can reach readyState
HAVE_FUTURE_DATA just after its OwnerDoc is removed from the docshell. If the
HTMLMediaElement wasn't paused, then it may start playing due to the readyState
change in HTMLMediaElement::ChangeReadyState().
For years we've had hard to reproduce issues where media started playing after
we've closed the tab; I bet this was the cause!
When we detect that the document has been removed from its DocShell,
HTMLMediaElement::NotifyOwnerDocumentActivityChanged() is called, and that
suspends the MediaDecoder just in case we need to resurrect the media element,
for example if the tab comes out of the BF cache. When we suspend we set
mPausedForInactiveDocumentOrChannel=true, and all other calls to
MediaDecoder::Play() are guarded by checks on
mPausedForInactiveDocumentOrChannel.
So we should also guard the MediaDecoder::Play() call in ChangeReadyState()
with a check on mPausedForInactiveDocumentOrChannel too.

This patch makes MediaDocumentStreamListener implement the
nsIThreadRetargetableStreamListener interface. This allows callers to
redirect the OnDataAvailable calls to another thread if possible. Since
ImageDocument's use ImageListener which inherits from this class, and we
are often viewing large images this way, it would be nice to move the IO
to the image IO thread.
For number controls, nsContentUtils::IsFocusedContent doesn't really do the
right thing, because the thing it thinks is focused is the anonymous text
element inside the number control. As a result, we weren't properly updating
the state of the currently-focused number control when hitting enter in it to
submit the form.
The HTMLFormElement change is enough on its own to fix the bug. The constraint
validation change is a just-in-case.
I haven't figured out a sane way to write a reftest for this, unfortunately:
the enter key press needs to look like a real user event to trigger the
submission behavior.

Sometimes when video is playing, a preroll ad plays, and that may be in a cross
origin iframe. If autoplay media is disabled, we require a user gesture in a
document before playback in that document is permitted, and we require each
origin to be gesture activated separately. So in the cross origin preroll video
add case, then the user will have to click once to unblock playback for the
cross origin ad, and then once the preroll ad finishes, the user will have to
click again to activate playback of the same origin content video.
This is a bad user experience.
So we should instead make gesture activation propagate up the doc tree
irrespective of crossing origins. This way, when the user clicks to activate,
all documents in that tab are also also effectively gesture activated, and so
can autoplay.

SeekToNextFrame is handled differently than other seeks by the
MediaDecoderStateMachine, and should not take place while other seeks already
are. Bug 1410225 implemented some changes in HTMLMediaElement to prevent this,
but it's still possible to move to a seeking state in the MDSM and accept
SeekToNextFrame (as in this bug).
This changeset changes the MDSM to reject SeekToNextFrame if a seek is already
happening. Since the MDSM now does this the changes from bug 1410225 can be
removed.
This has the functional change of the promise from SeekToNextFrame being
rejected if the seek in not performed due to another seek. Previously the
promise would succeed when the other seek completed. This seems sensible as the
next frame seek does not actually take place.

We currently observe changes to HTMLMediaElement::mPaused via a hand-rolled
wrapper class. We can use use mozilla::Watchable<> and avoid rolling our
own equivalent here.
This also paves the way for using state watching on other observable state
in HTMLMediaElement.

We don't need to track this state anymore, as we don't need to delay calling
MediaDecoder::Play() or delay firing the "playing" event anymore.

I don't think we should allow media without audio tracks to autoplay because:
* It means play() before loaded metadata behaves differently than play()
called after loaded metadata.
* With the current impl we dispatch the "play" event and then the "pause"
event when we decide we should block, which may confuse some sites' controls.
* Delaying running the play() algorithm until we've loaded metadata would add
significant complexity, and may break sites.
* Chrome doesn't have this provision, meaning the complexity required to
support it will not result in much benefit to us.

This patch splits FontTableURI and BlobURL in 2 classes:
FontTableURIProtocolHandler and BlobURLProtocolHandler
both under mozilla::dom.
It also removes a memory reporter because that report is already covered by the
BlobURL one.

rename : dom/file/nsHostObjectProtocolHandler.cpp => dom/file/BlobURLProtocolHandler.cpp

Same approach as the other bug, mostly replacing automatically by removing
'using mozilla::Forward;' and then:
s/mozilla::Forward/std::forward/
s/Forward</std::forward</
The only file that required manual fixup was TestTreeTraversal.cpp, which had
a class called TestNodeForward with template parameters :)

This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

When we implement InputEvent.inputType, we need to set a stack class to record
which edit action is currently handled. However, currently, we call smaller
jobs as edit action. For example, when user types a character at selecting
some characters, then, EditAction::deleteSelection is performed first, then,
EditAction::insertText is performed. However, for the InputEvent.inputType,
we need inserText information. So, for making new enum EditAction, we need
to rename current EditAction to EditSubAction.
And also this renames related stuff:
EditorBase::mIsInEditAction -> EditorBase::mIsInEditSubAction
EditorBase::IsInEditAction() -> EditorBase::IsInEditSubAction()
EditorBase::mAction -> EditorBase::mTopLevelEditSubAction
TextEditRules::mTheAction -> TextEditRules::mTopLevelEditSubAction
EditorBase::StartOperation() ->
EditorBase::OnStartToHandleTopLevelEditSubAction()
EditorBase::EndOperation() ->
EditorBase::OnEndHandlingTopLevelEditSubAction()
AutoRules -> AutoTopLevelEditSubActionNotifier
RulesInfo -> EditSubActionInfo
