CSS-TEXT-3 § 7.3.
`text-justify: distribute` is not supported.
The behavior of `text-justify: none` does not seem to match what Firefox
and Chrome do, but it seems to match the spec.
Closes#213.
This used to conflict with the util crate from the standard library, which
has long since been removed.
The import in layout has not been changed because of a conflict with the
util mod there.
Avoids duplicated code when implementing the CSS properties accessors in
CSSStyleDeclaration WebIDL. Servo internal CSS properties are not
accessible.
CSS property "float" is unnacessible because we currently lack support
for BinaryName IDL annotation (#4435).
Fixes#4429, #4430.
Notes:
* This adds `#![allow(missing_copy_implementations)]` to components/*/lib.rs. I'm not sure how to approach the missing Copy warnings (are there things for which Copy should NOT be implemented, and how can I tell?) so I stuck this in to make life easier when looking through the warnings. I can easily remove this if necessary.
* This leaves the following type of warnings, which I couldn't figure out how to approach (I'll investigate it later if no one else wants to).

through display list building.
The old `flow_origin` concept was ill-defined (sometimes the border box
plus the flow origin, sometimes including horizontal margins and
sometimes not, sometimes including relative position and sometimes not),
leading to brittleness and test failures. This commit reworks the logic
to always pass border box origins in during display list building.
This does not implement any notion of CSSStyleDeclaration objects that do not have an owning element; there's no actual CSS object model in play here. This does support setting and getting properties of the style attribute for HTMLElement, and tries to implement the ambiguous CSS value serialization spec.
