This implements just enough of [Touch Events](http://w3c.github.io/touch-events/) to enable scrolling on Android without regressing basic single-touch interaction like clicking on links.
Dragging a page will scroll it, unless the page calls `preventDefault` on the "touchstart" event.
Does **not** yet support pinch zooming or other multi-touch gestures or events.
Includes a `-Z convert-mouse-to-touch` command line flag for testing on non-touch platforms. This is also enabled by default on Android because Glutin currently translates touch input to mouse events on Android.

Instead of always promoting iframes to StackingContexts, integrate them
into the display list. This prevents stacking bugs when
non-stacking-context elements should be drawn on top of iframes.
To accomplish this, we add another step to ordering layer creation,
where LayeredItems in the DisplayList are added to layers described by
the LayerInfo structures collected at the end of the DisplayList.
Unlayered items that follow these layered items are added to
synthesized layers.
Another result of this change is that iframe layers can be positioned
directly at the location of the iframe fragment, eliminating the need
for the SubpageLayerInfo struct entirely.
Iframes are the first type of content treated this way, but this change
opens up the possibility to properly order canvas and all other layered
content that does not create a stacking context.

This makes use of the new functionality that allows iframes to generate their own pipeline IDs in order to remove any knowledge of subpage ids from the compositor.
(This is the first of several commits removing subpage from parts of servo).

This doesn't change any functionality, but it's the first step towards removing SubpageId.
Adding this change now will allow us to gradually change over code referencing subpage id rather than in one massive PR.
Introduces a namespace for pipeline ID generation - there is a namespace for the constellation thread, and one per script thread.

StackingContexts are added to layers when it is necessary to maintain
their ordering on top of other layered StackingContexts. Instead of
tracking the information about a layer scattered around into different
structs, combine it all into LayerInfo. LayerInfo will be used in the
future to hold layer information for DisplayItems that are layerized
independently of StackingContexts.

The old code that attempted to do this during layout wasn't able to work
for multiple reasons: it couldn't know where the iframe was going to be
on the page (because of nested iframes), and at the time it was building
the display list for a fragment it couldn't know where that fragment was
going to be in page coordinates.
This patch rewrites that code so that only the size of an iframe is
determined during layout, and the position is determined by the
compositor. Layout layerizes iframes and marks the iframe layers with
the appropriate subpage ID so that the compositor can place them
correctly.
Closes#7377.

There were two problems here:
(1) The animation state update function was only called when nodes were dirty or there were new animations.
(2) When all animations for a node expired, the entry from the hash table was not removed.
The result was that once an animation began, the compositor would be running as fast as it can forever.
Fixes#7721.

Currently pseudo-elements, like the fragments created for ::before and
::after, with layers will have the same LayerId as the body of their
owning fragments. Instead all LayerIds should be unique.

StackingContexts that should be painted on top of StackingContexts that
are already layerized should automatically get their own layer. This
will ensure proper painting order.

Previously, StackingContexts might have a PaintLayer. We switch the
ownership, for several reasons:
* We want PaintLayers to potentially contain something other
than a StackingContext soon.
* We want to delay the creation of PaintLayers until the last
minute, so that we can synthesize new layers for sandwiched
content.
This commit also implements the second goal. Instead of creating
PaintLayers during layout itself, wait until we are sorting and
layerizing a completed DisplayList.

Also adds HeapSizeOf implementations/derive for some types. I've used "Cannot calculate Heap size" as a reason everywhere, because my imagination is rather limited. If you'd like me to change this message for specific types, please write something like this: "Trusted - Cannot calculate Heap size for Trusted" so that it would be easier for me to replace them through a script :)

Known issues:
* Display list optimization can sometimes optimize out elements that
should be shown. This affects the Enyo demo.
* The `overflow: scroll` container doesn't clip the inner layer properly
when borders, border radius, etc. are present.
* `overflow-x: scroll` and `overflow-y: scroll` don't work individually;
elements are scrolled all at once.
Note that multiple layers per stacking context aren't needed for the Enyo demo; rather the issue is that the height of the main area is being calculated incorrectly. (It looks like JS is measuring the height and poking in an explicit value that is too tall.)

…s for frame treese in script tasks.
This underreports by a significant amount, since only Document, Window and CharacterData (ie. text) nodes are fully represented. That being said, every HTML element in the tree is measured, but only counted as a Node. It's easy to improve this, it just requires adding the appropriate HeapSizeOf derives and increasing the granularity of `measure_memory_for_eventtarget`. google.com shows a dom-tree value of 0.24 MB for me at the moment.

This commit introduces the `serde` dependency, which we will use to
serialize messages going between processes in multiprocess Servo.
This also adds a new debugging flag, `-Z print-display-list-json`,

Supersedes #6488. Changes since then:
* Fix a few places where we needed cfg(feature = "window") in order to compile without the feature.
* Zoom-in shortcut now works both with and without shift. (Uses a guard because I couldn't think of another way to do it without CTFE.)
* Back/forward shortcuts now correctly use Alt on non-Mac platforms.
* The back/forward shortcuts that use square brackets are now non-Windows, rather than Mac-only. This roughly matches XP_UNIX: http://hg.mozilla.org/mozilla-central/file/d4c4ce7f060c/browser/base/content/browser-sets.inc#l354
