Summary:
FlushTarget wants to decide whether we should flush the parent document or all
of them. However, the only point of flushing parent documents is that media
query changes could affect the document we really want to flush.
That's completely pointless if we actually don't flush the subdocument, so just
skip doing that. This case is already checked (see the DocumentNeedsRestyle
stuff, which is also somewhat poorly named, which walks up the document chain).

Now that what we use to decide whether a document is styled by Servo are only
prefs and the doc principal, we don't need to inherit the style backend type,
since unless the pref has changed, the result will be the same.

The autofocus attribute on form elements forces layout in CheckIfFocusable.
To avoid unpleasant FOUCs, defer autofocus processing until frames are
constructed in PresShell::Initialize.
Resolve the race between nsAutoFocusEvent running and page load by checking the
readystate at time of event posting. Skip autofocus if the element moved to a
different window in the meantime.

Everything that needs them up-to-date will call flush appropriately, there
should be no need to do it manually.
This way we coalesce all the stylist updates until the next style flush in the
best case, or until one of the consumers actually needs them.

We don't need to collect whole descendants documents.
This patch intentionally leaves animation events handling which is another
caller of CollectDocuments in nsRefreshDriver since the animation part will
be fixed in a different way in bug 1415780.

In contrast to nsIDocument::EnumerateSubDocuments(), this new function is
supposed to work with the callback function which does not mutate any state
in the document, and also this function checks all descendant documents even
if there is a descendant that the callback function returns false.

This is a short-term solution to our inability to apply CSP to
chrome-privileged documents.
Ideally, we should be preventing all inline script execution in
chrome-privileged documents, since the reprecussions of XSS in chrome
documents are much worse than in content documents. Unfortunately, that's not
possible in the near term because a) we don't support CSP in system principal
documents at all, and b) we rely heavily on inline JS in our static XUL.
This stop-gap solution at least prevents some of the most common vectors of
XSS attack, by automatically sanitizing any HTML fragment created for a
chrome-privileged document.

Returning a zero-sized viewport in the case there's no shell / pres context.
For now, no other change yet. After this we can start tweaking the ShadowRoot
Stylist setup, and even try to return computed styles without a document \o/.

Most of the Shadow DOM related code are behind "dom.webcomponents.enabled" and
this pref is only used by Shadow DOM right now, so we should rename it to
"dom.webcomponents.shadowdom.enabled"

In order to write tests, I would like to create an method that allows chorome js can directly set the user-activation flag.
Therefore, I need to move all these details into nsDocument, then we could easily simulate the user activation.

For top level frame, it should also be activated when user activate its child frame.
eg. A (youtube.com) -> B (ad.com), when user activate B frame, the A frame would also be activated.
