With `--no-default-features --features default-except-unstable`, more crates can now be compiled on stable Rust. This will help integrate them in rustc’s regression testing and compiler performance benchmarking.

At the moment, layout panics if it discovers an iframe without a nested browsing context. Under normal circumstances, this is reasonable, but it requires very tight synchronization between script, layout, the constellation and the compositor. In particular, if a layout is in progress when an iframe's browsing context is discarded, this can trigger panic.
This PR fixes this in two ways:
1. Making the pipeline and browsing context ids optional in layout's representation of an iframe.
2. Shutting down layout before discarding a browsing context, rather than after.
This is belt and braces.

These are the inter-dependent patches of bug 1392161. We want to handle
extreme small lengths carefully for some properties, such as transform, so we
shouldn't use |Au| as the computed value of specified::Length. Now, we introduce
a new type, CSSPixelLength, which is a wrapper of CSSFloat, and it is the
computed value of specified::Length, so we can keep the fractional part
of computed::Length.

Instead of only promoting flows with positioned fragments to containing
blocks, also do this for flows which have the transform, perspective or
filter properties set. This is what the spec requires and also fixes
some failing tests. It will allow us to stop creating stacking contexts
for overflow:hidden and overflow:scroll flows.
Fixes#18091.

Info about the big picture and the goals of the WebGL refactor in this thread: https://groups.google.com/forum/#!topic/mozilla.dev.servo/0WMGz60kKzQ
I tried to reduce this PR as much as possible as requested in the thread. I'll do separate PRs for other features (e.g.: Batch messages or use shared memory to improve frame times) or fixes.
Some tips to ease the review process:
- Most changes in DOM objects follow the same pattern (remove CanvasMsg wrapper and use the new sender method).
- WebGLCommands are the same ones as before (moved from webrender_api). So those lines are already reviewed.
- See WebGL traits in [components/canvas_traits/webgl.rs](https://github.com/servo/servo/pull/17891/files#diff-8701045d01505418701d0631d4d45562)
- See WebGLThread and WR External Image bridge in [components/canvas/webgl_thread.rs](https://github.com/servo/servo/pull/17891/files#diff-281554879f39a2a041f7a69d442a5d2e)
- The implementation submitted in this PR creates a single `WebGLThread` for all ScriptThread/Pipelines. See that in [components/canvas/webgl_mode/inprocess.rs](https://github.com/servo/servo/pull/17891/files#diff-250070c6c5a38c7f9fa0f5b3c101f68b)
The conformance tests will help to guarantee that we don't miss anything.

According to the spec, the computed value of transform is as specified, but
with relative lengths converted into absolute lengths, so in Gecko, we do
nothing while computing the value of rotate3d(), and do normalization in
ProcessRotate3D(). If the direction cannot be normalized, we treat it as
an identity matrix.
However, in Servo, we do normalization in to_computed_value(), and looks
like we are trying to normalize any kind of direction vectors, so according
to the spec, let's move the normalization into Fragment::transform_matrix(),
and return an identity matrix if we cannot normalize its direction vector.

Some properties only accept non-negative values, or values greater than or equal to one. It is possible to produce an negative interpolated values while using negative timing functions, so we have to apply a restriction to these values to avoid getting invalid values.
For example, line-height must be non-negative, but the output progress of some timing functions (e,g. cubic-bezier(0.25, -2, 0.75, 1)) may be a negative value, so the interpolated result of line-height is also negative.

These are the interdependent patches of Bug 1335998. We want to do interpolation and accumulation for mismatched transform lists, so introduce ComputedOperation::InterpolateMatrix and ComputedOperation::Accumulation. Both arms store the from_list and to_list, and resolve them until we have the layout information. For the Servo part, we haven't implemented how to read the transform lists in layout/fragment.rs, but I think it would be easy. (related issue #13267)

-moz-transform property is an alias shorthand property. It has transform as sub-property but their parsing is different in some cases(matrix/matrix3d). -moz-transform also accepts LengthOrPercentage in the nondiagonal homogeneous components of matrix and matrix3d.
It looks like length and percentage values are getting computed to number directly. For example 120px converts into 120 and calc(120px + 20%) converts into 140. So I did like this. But we need to check this behavior again to be sure, I guess.
Also I spent half day investigating why matrices are not serializing after this change and found out their ToCss functions is not completely implemented yet 😄 I was going to implement them but there is an easy issue about it(#15194) so I left it that way. Probably all tests won't pass without it.

The design of initiating network requests from the image cache thread was simple, but it makes it difficult to implement image loading that conforms to the HTML specification. These changes make the implementation of HTMLImageElement responsible for network requests for `<img>` elements, and CSS-based images (background-image, bullets, etc.) are requested by the script thread to ensure that the layout thread does not attempt to retain unsafe pointers to DOM nodes during asynchronous operations.

<!-- Please describe your changes on the following line: -->
When calculating size of replaced element that has intrinsic aspect ratio, we need to multiply the ratio if one of the dimensions has definite size. And we can not precompute the ratio and store it as a float, because doing so may result one pixel difference in calculation for certain images, thus make some tests fail. So it may overflow when the dimension lengths are large, and this pull request convert them to `i64` before multiplication.

<!-- Please describe your changes on the following line: -->
According to https://github.com/servo/servo/pull/3069 the cached thread local context is introduced for green threads. Now green threads has gone, and the existence of cache force us to create a `LayoutContext`, an `AssignISizes` and an `AssignBSizes` for each flow during parallel layout, so the pull request tries to remove it. And it also switch `assign_inline_sizes()` to accept a `LayoutContext` parameter, as according to my current design we need to do full layout to some flex items for column flexbox during assign isize traversal.
Part of #14123.

This patch allows Servo to incrementally reflow truncated fragments correctly.
* The untruncated version of a fragment is preserved, and when incrementally reflowing, the untruncated version is what gets reflowed. If it needs truncated, it will get truncated again.
* The ellipsis fragments are skipped when incrementally reflowing a line. If it is still needed, it will be recreated.
