This patch makes Element::GetAnimationPlayers return not only current animations
but also animations that have finished but are filling forwards. This brings the
implementation into line with recent changes to the Web Animations spec and
allows querying all the animations that are currently affecting an element or
which are scheduled to do so in the future.
It's not the player that's "current" (a Web Animations term for an animation
that hasn't yet finished), but its source content, if any. This patch renames
the method on AnimationPlayer accordingly.
At the same time this patch moves the method to the header file since it's
quite simple and could possibly benefit from inlining.
- Updated ScrollTo method in nsGlobalWindow to accept a
mozilla::dom::ScrollOptions parameter to select between the instant
and smooth MSD motion.
- Updated WebIDL binding boilerplate scrolling functions in nsGlobalWindow
to pass the correct value of mozilla::dom::ScrollBehavior to the
implementation and functions, activating smooth scrolling.
- These functions will need to be updated again to support the scroll-behavior
CSS property in Bug 1010538.

- Extended the Element and Window webidl interfaces as described in the
CSSOM-View smooth-scrolling specification.
- The Element.scrollTop and Element.scrollLeft changes have been omitted
until either WebIDL is extended to allow properties to have union datatypes
that contain dictionaries or the CSSOM-View smooth-scroll specification
is upddated. This will not prevent the other interface changes from being
useful.
- Implemented wrapper functions for the nsGlobalWindow to connect to the new
WebIDL bindings. The ScrollOptions parameters are ignored in this patch,
and used in Part 3 of this patch series.

Now that we have both AnimationPlayer and Animation in use we need to clarify
which object we are referring to. This patch renames a number of member and
local variables to better reflect whether they point to an AnimationPlayer or an
Animation.
This patch is mostly renaming only with one exception. Since we are touching
a number of local variables used in loops (for looping over the array of
animation players) we take the opportunity to replace a number of instances of
uint32_t with size_t since that is the preferred type for array indices now.
This patch renames mozilla::ElementAnimations to mozilla::dom::AnimationPlayer
and moves the code from layout/style/AnimationCommon.cpp to
dom/animation/AnimationPlayer.cpp.
It also moves various helper classes needed by AnimationPlayer to
AnimationPlayer.cpp and moves them from the mozilla::css namespace to the
mozilla namespace.
Beyond that, there are no functional changes contained in this patch.
The renaming of various members and variables that used to refer to
ElementAnimation objects but now refer to AnimationPlayer objects--to give them
a more appropriate name--is performed in a subsequent patch.

This patch adds the WebIDL definitions and implementation of
getAnimationPlayers on Element.
It does not include the full definition of AnimationPlayer but only readonly
versions of the currentTime and startTime attributes since these are easy
to implement and enable identifying the different animations that are returned
for the sake of testing.
Web Animations defines getAnimationPlayers as only returning the animations that
are either running or will run in the future (known as "current" animations).
This will likely change since it seems desirable to be able query animations
that have finished but are applying a forwards fill. For now, however, this
patch makes us only return animations that have not finished.
This patch also removes an assertion in ElementAnimation::GetLocalTime that
would fail if called on a finished transition. This assertion is no longer
necessary since an earlier patch in this series removed the overloading of
the animation start time that meant calling this on a finished transition
was unsafe. Furthermore, this assertion, if it were not removed, would fail
if script holds onto a transition and queries its start time after it
completed.
This patch was mostly generated with the following command:
find . -name "*.h" -o -name "*.cpp" | xargs sed -e '/WrapObject(JSContext/ {; N; s/\(WrapObject(JSContext *\* *a\{0,1\}[Cc]x\),\n\{0,1\} *JS::Handle<JSObject\*> a\{0,1\}[sS]cope/\1/ ; }' -i ""
and then reverting the changes that made to
dom/bindings/BindingUtils.h, since those WrapObject methods are not
the ones we're trying to change here, plus a bunch of manual fixups
for cases that this command did not catch (including all the callsites
of WrapObject()).
