In the case where scroll-snap-type is specified for the scroll container, the
scroll-padding is also factored into in ScrollFrameHelper::ComputeScrollSnapInfo
which is called via ScrollFrameHelper::ScrollToWithOrigin. It doesn't double
the scroll-padding value, but it's actually redundant, we should avoid it.
We could separate the functionality of ScrollToWithOrigin, one is to scroll
to a given element, the other is to scroll to a given position. The former will
be used for Element.scrollIntoElement and relevant stuff, the latter will be
used for Element.scrollTo and relevant stuff. That's being said, as of now, we
have still the old scroll snap implementation, so the separation will introduce
complexity, the separation should be done once after the old implementation
removed.
There are 9 call sites of nsIPresShell::ScrollContentIntoView:
nsIPresShell::GoToAnchor
nsIPresShell::ScrollToAnchor
Element::ScrollIntoView
We definitely needs scroll-padding and scroll-margin for these functions.
nsCoreUtils::ScrollTo
This is used for Accesible::ScrollTo which scrolls to a given accesible node,
probably we should behave as what Element::ScrollIntoView does.
Accessible::DispatchClickEvent
Similar to the above, similated various mouse events on a given target node.
PresShell::EventHandler::PrepareToUseCaretPosition
PresShell::EventHandler::GetCurrentItemAndPositionForElement
Both are for context menu, we shouldn't consider scroll-padding and
scroll-margin.
nsFormFillController::SetPopupOpen
This is used for autocompletion popup, we shouldn't consider scroll-padding
and scroll-margin.
nsFocusManager::ScrollIntoView
This is bit unfortunate, we should use scroll-padding and scroll-margin
depending on call site of this function. Bug 1535232 is for this case.
cssom-view/scrollIntoView-scrollPadding.html which has some tests that is
actually testing scroll-padding with scrollIntoView passes with this change.
The reftest in this change is a test case that the browser navigates to an
element with specifying the anchor to the element.

Normally autocomplete results are cached based upon the search string but to get the desired behaviour we want two different sets of results for the same search string depending on how the autocomplete search was started:
a) Via automatically focusing a password field.
b) Every other method of starting an autocomplete search.
In order to not have cached results used, the result code for case (a) [an empty result] will be `RESULT_FAILURE` and I've updated the autocomplete code to not re-use an error result.
In the coming months we may be rewriting our content autocomplete code but that would be too risky to uplift to 67 so for now I'm tracking when satchel automatically opens the popup upon focus and then using that state in the autocomplete result creation code to know whether to include the footer.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
If class A is derived from class B, then an instance of class A can be
converted to B via a static cast, so a slower QI is not needed.

Some pages, like the Google login form, submit information on keydown, that
causes us to not autocomplete, because we handle keypress instead.
The patch changes autocomplete to happen on keydown.
Unfortunately formautofill also uses keydown and tries to access popup data too
late, thus it needs some hacks to work properly.
In general the formautofill code has too many indirections due to e10s, and that
makes the fix more fragile than we'd want. Ideally content autocomplete should
have its own codebase, rather than sharing the same controller as chrome code.

The autocomplete module listens to keypress event for both printable keys and
non-printable keys a lot. However, we'll stop dispatching keypress event for
non-printable keys in the default event group of web content. So, autocomplete
should listen to keypress events at the system event group.
Note that it's difficult to change keypress event listeners to keydown event
listeners because if we stop keypress events at preceding keydown event in
autocomplete or satchel module, some other modules fail to handle keydown or
keypress event before autocomplete and it's not easy to investigate which
module's which keypress event listener should be changed to keydown event
listener. Therefore, this patch doesn't do it at least for now.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.
