There are a few canvas2d-related dependencies that haven't updated, but they
only use euclid internally so that's not blocking landing the rest of the
changes.
Given the size of this patch, I think it's useful to get this landed as-is.
Transforms should always create containing blocks. This bug already
existed in Servo, but was covered up by the reference frame id
replacement feature in WebRender. Now that we create reference frames
manually we need to fix it.
Move display_list_builder.rs and webrender_helpers.rs
along with the new file to components/layout/display_list/
Remove apparently unused IdType enum.
Only variant used was OverflowClip.
See #19676
These are two different passes during layout, but previously they
shared a state object. While some of the members are the same, many are
different so we separate them out into two separate objects. We also
change the HashMaps of these state objects to use the FnvHashMap.
Add support for position:sticky
This leverages the position:sticky support in WebRender to bring basic
support for position:sticky in Servo. There are still some issues with
nested sticky flows as well as a few other corner cases. Tests are
imported from WPT and can be removed once we update to the latest
version.

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).
Fix margin size calculation for TableWrapper
<!-- Please describe your changes on the following line: -->
Fixes inline size calculation for TableWrapper. The table's width was always reaching the inline size equation solver as a specified variable, which was causing the system to be overdetermined when there was a margin specified for the table, and this caused the overflow reported in #12748. The fix consists in handling three cases when the table's width is not specified: if the preferred size of all columns fits, it is returned; if the minimum size does not fit, it is returned instead (it will overflow), otherwise, it is returned as a free variable (that should be solved together with the margin to some value above the minimum width and below the preferred width).

Collect scroll roots during the collect_stacking_context phase instead
of during display list construction. This will be useful in order to
collect containing block scroll roots as well as to give scroll roots
sequential ids in the future. This change also pulls stacking context
children out of the StackingContext struct itself, which should reduce
very slightly the memory used by the finished display list. This also
simplifies the DisplayListBuilder because it no longer has to maintain
a stack of ScrollRootIds and StackingContextIds and can instead just
rely on the program stack.
This is a step in disassociating scrolling areas from stacking
contexts. Now scroll areas are defined by unique ids, which means that
in the future stacking context will be able to contain more than one.
Implement sequential fallback to float speculation
This shouldn't impact any pages that are already rendering correctly, but it is a very naive implementation of this pass.

<!-- Reviewable:end -->
Simplify the way that stacking contexts are collected. Instead of
passing the StackingContextId down the tree, pass the parent
StackingContext itself. This will allow future patches to get more
information about the parent stacking context (such as location).
Also remove the return value of collect_stacking_contexts, which was
unused.
