I'm working on resolving https://github.com/servo/servo/issues/8213 as per the spec online and feedback in the servo channel. Note that currently I cannot build (and thus test) my code, so this is a bit of a rough first draft. I'd still like feedback on my progress, and I hope that there is another way for my code to be tested.

This is the strategy we'll need to take for attributes, and so this change
puts us in a position to handle attributes and state the same way.
This does mean that we stop taking care to track the situations where our
state has reverted to the original state, with no net change. I think that's
probably of negligible value though.
For some reason when I wrote this code I mixed up the rules for pseudo-elements
(rightmost, maximum of one) with those of pseudo-classes (which have no such
restriction). This caused a correctness issue which can be demonstrated with the
associated reftest modification.
Eliminate LAYERS_NEEDED_FOR_DESCENDANTS flag
This flag is no longer necessary, because stacking contexts can now
create layers lazily for content that needs to be stacked above a
layer. This should reduce the number of layers on pages, hopefully
reducing overdraw.

New Android suppport
r/f? @mbrubeck
No need to r+ urgently; I want to do a little bit more testing of the release build, but I'm hoping to land this bit (moving to a more sane build process) next week.
The new version of building an APK:
1) Removes the glutin-based APK builder from the link step
2) Adds a build.rs step to the build of the final Servo library that adds the native code required by glutin's android_rs_glue (e.g., `ANativeActivity_onCreate` definition)
3) Replaces the link step with a `fake-ld.sh` script that instead creates a libservo.so
4) Adds a new mach `package` step to build the APK that has some Rust code that builds the library from a set of in-tree build files
This setup fixes a number of problems:
1) We can use gdb, because we use `ndk-build`, which adds the .gdbserver info, plus we keep around all of the build files (also required by the ndk gdb)
2) We can add more Java code & hooks to handle Android intents
3) We no longer have any git submodules or the awkward two-step build with android-rs-glue
Many other setups were tried (and failed). The most obvious ones is building a libservo.so from a `dylib` target from the servo build on Android. This doesn't work because you can't have a different default lib target on one platform than others in Cargo, and you also can't pass it in from the commandline (e.g., --lib does not have a dylib arg). Additionally, if you don't go through the intermediate libservo.rlib step (which removes unused symbols), then you end up with a TON of missing symbols because our -sys crates are super sloppy about that. I spent a few weeks beginning to clean them up, but since it's something we can't easily enforce (and new -sys packages will have this problem, too, since it's only an issue with the Android loader), it made more sense to me to just have the build set up to discard those unused bits of code before they ever get to the linker, much less the loader.

Properly resize iframe root layers
When a layer containing an iframe changes, we also need to resize the
root layer of the subpage. This ensures that content from the child
layer tree is masked to the new size.

Always produce a DisplayList when processing nodes for display list
construction. StackingContexts are now added to the positioned content
section of DisplayLists. This makes the code a bit simpler and opens up
the possibility of producing a StackingContext in another section of
the DisplayList. This doesn't change behavior, but is a cleanup
prerequisite for proper inline stacking context support.
Simplify implementation of '<canvas>' 'width' and 'height' attributes.
Strictly speaking, this affects correctness for extremely large width and height values... but that's unlikely to matter in practice.

This should make it somewhat easier to experiment with alternative
representations in the future. To reduce churn, this commit leaves the String
field public, though.
Also, this will allow us to use the default String type to represent the IDL
USVString type, which explicitly forbids unpaired surrogates, ans as such is
a better match to the Rust String type.
Allow retrieving width/height for non-positioned elements
This was causing a bunch of tests in tests/wpt/web-platform-tests/html/semantics/embedded-content/the-canvas-element/size.attributes* to fail. They were returning "auto" instead of the correct size. They still fail because the returned size is off by a few pixels, not sure why yet. But this is more correct and may fix other failing tests.

Mix stacking contexts into the positioned content list
Sometimes positioned content needs to be layered on top of stacking
contexts. The layer synthesis code can do this, but the current design
prevents it because stacking contexts are stored in a separate struct
member. In order to preserve tree order, mix stacking contexts into the
positioned content list, by adding a new StackingContextClass
DisplayItem. Such items do not have a base DisplayItem.
In some ways this simplifies the code, because we no longer have to
have a separate code path in the StackingContextLayerCreator.

Fix several bugs causing the page to reflow on every mouse move event
After all these changes are applied, Hacker News and GitHub only repaint and reflow nodes that actually have hover styles applied when the mouse moves over them.

add get_raw_layout_value (HTMLInputElementHelpers)
This resolves#8107
Previously the index of the insetion point for a password input was
calculated using the scrambled string based on the edit point in the
raw string. That could lead to a wrong position of the caret. This
commit changes this behavior to calculate the insertion point using
the raw string.
