First, we define computed::CSSPixelLength which contains a CSSFloat, a
pixel value, and then we replace computed::Length with CSSPixelLength.
Therefore, the |ComputedValue| of NoCalcLength, AbsoluteLength,
FontRelativeLength, ViewportPercentageLength, CharacterWidth, and
PhysicalLength is CSSPixelLength.
Besides, we drop NonNegativeAu, and replace computed::NonNegativeLength
with NonNegative<computed::Length>. (i.e. NonNegative<CSSPixelLength>)
This is a better approach than relying on
contains_positioned_fragments, because in the future other properties
will create absolute containing blocks.
Add values::computed::NonNegativeAu, so BorderSideWith could be computed
to this non-negative Au, for the following properties:
1. outline-width
2. border-{*}-width
3. column-rule-width
4. -webkit-text-stroke-width

The alias is left there temporarilly and will be removed completely in a later commit where
also components/style/gecko/generated/structs_{debug|release}.rs are re-generated (they still
use the old alias).
This commit splits the style and layout data in two separate refcells.
These transmutes have been a source of trouble (for example on Android), and
they feel like a hack anyway.
Fixes#16982
Since for nested inline elements non-inheritable properties are
properly stored in the inline context of an inline fragment, so get
rid of them on the style.
Now that cascade() gets a Device, we can use the default computed values from
there to avoid propagating that state all over the place.

In support of this goal, the layout thread collects information about
CSS images that are missing image data and hands it off to the script
thread after layout completes. The script thread stores a list of
nodes that will need to be reflowed after the associated network
request is complete. The script thread ensures that the nodes are
not GCed while a request is ongoing, which the layout thread is
incapable of guaranteeing.
The image cache's API has also been redesigned in support of this
work. No network requests are made by the new image cache, since it
does not possess the document-specific information necessary to
initiate them. Instead, there is now a single, synchronous
query operation that optionally reserves a slot when a cache
entry for a URL cannot be found. This reserved slot is then
the responsibility of the queryer to populate with the contents
of the network response for the URL once it is complete. Any
subsequent queries for the same URL will be informed that the
response is pending until that occurs.
The changes to layout also remove the synchronous image loading
code path, which means that reftests now test the same code
that non-test binaries execute. The decision to take a screenshot
now considers whether there are any outstanding image
requests for layout in order to avoid intermittent failures in
reftests that use CSS images.

style: Add a "start_end()" method to LogicalMargin
<!-- Please describe your changes on the following line: -->
Add a `LogicalMargin::start_end()` method that receives a `Direction' parameter. This is useful for some layout that is symmetric in inline and block directions, like flexbox.
Part of #14123.

Don't mark the first/last fragment of an {ib} split as FIRST/LAST_FRAGMENT_OF_ELEMENT.
<!-- Please describe your changes on the following line: -->
This change allows inline margins, borders, and padding to interact correctly with {ib} splits.

Set the flag of the fragment of children in a flex container according
to the direction of the container. The mark is done on the fragment
because flex item enstablish a stacking context when its z-index is
non-zero ,despite its `position' property.
