I don't think this code is called when there is no document element, but I
added assertions to make sure we notice in case I was wrong.

I don't believe there is a case where it would make sense to drop the
ScriptReflow struct without joining the script thread. This approach should
be somewhat more robust, and avoids the code smell of a RAII guard in an
otherwise unused variable.

This patch makes DOMString an opaque wrapper round String (currently it's a transparent wrapper).
The changes are:
* Replacing DOMString(foo) by DOMString::from(foo).
* Replacing foo.0 by String::from(foo).
* Adding functions clear, push_str and extend for in-place mutation of DOMStrings.
* Replacing DOMString by String in other threads (devtools, storage and filereader).
* Making DOMString implement !Send.
* Removing the pub attribute from the contents of DOMString.
This enables experimenting with other string representations in the DOM.

Instead of making a stacking context out of inline fragments parent
flow, make the inline fragment itself the stacking context. This fixes
positioning and rendering of these sort of fragments and prevents
over-layerization.

Stylesheets for `HTMLLinkElement`s are now loaded by the resource task, triggered by the element in question. Stylesheets are owned by the elements they're associated with, which can be `HTMLStyleElement`, `HTMLLinkElement`, and `HTMLMetaElement` (for `<meta name="viewport">).
Additionally, the quirks mode stylesheet (just as the user and user agent stylesheets a couple of commits ago), is implemented as a lazy static, loaded once per process and shared between all documents.
This all has various nice consequences:
- Stylesheet loading becomes a non-blocking operation.
- Stylesheets are removed when the element they're associated with is removed from the document.
- It'll be possible to implement the CSSOM APIs that require direct access to the stylesheets (i.e., ~ all of them).
- Various subtle correctness issues are fixed.
One piece of interesting follow-up work would be to move parsing of external stylesheets to the resource task, too. Right now, it happens in the link element once loading is complete, so blocks the script task. Moving it to the resource task would probably be fairly straight-forward as it doesn't require access to any external state.
Depends on #7979 because without that loading stylesheets asynchronously breaks lots of content.

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.

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.

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.

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.

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.

Given the comments above the match statement, it seems that fixed-pos check should match only block elements in this case. Doing this change seems to partially resolve the issue where list items with `position:fixed;` styling are not displaying their bullet points. This change only resolves the issue for list items with `list-style-position: inside`, outside positioning is still not functioning correctly.

Previously, this was most noticeable with 45deg gradients, where the gradient would end too early, and the remainder was filled with a solid color.
(This also fixes gradients on webrender, which relies on the start and stop points being correct).

This reduces some unnecessarily tight coupling, makes it clearer what these functions do, and may help avoid bugs where we would return from such a function without updating the relevant field.
It is also a precondition for some future experimentation I'm thinking of doing with this querying design.

Canvas is currently given a layer at the stacking context level.
Instead it's DisplayItem should be given a layer directly. This fixes
painting order issues where canvases are painted on top of other
positioned content that is later in tree order. It always simplifies
the code a bit.

This adds the input caret for textareas. Although, it does not handle multiline textareas correctly. The caret gets displayed for each line.
I'll look into that but that will take more time. Some feedback on this small patch would be appreciated though.
