Converting the specified value of some properties into a computed value
depends on the value of other properties. For example, the `em` unit
of any length depends on the `font-size` property.
Previously, we would do a first pass over applicable declarations
to build up a `values::computed::Context` struct with a number of fields
for each such piece of data from other properties.
This simplies the struct by instead having it contain the
set of computed values (for a given element) that is being populated
and classify properties into "early" and "other",
such that the only dependencies can be from "other" to "early".
We iterate applicable_declarations twice, first cascading "early" properties
then "other".
Unfortunately, it’s not easy to check that this classification is correct.
Update WebSocket blocked ports to match the Fetch spec
Adresses #9949.
This adds a function that tests whether a request should be blocked or not based on it's url's scheme and port. It also adds testing for port restriction to the `main_fetch` method. More info in eb07418c83.
@Ms2ger In https://github.com/whatwg/html/issues/841, @annevk proposes to remove port restrictions from websockets. Should we go ahead do that, given that the spec hasn't been changed yet?

compositing: In borderless mode, don't show the window until the page has loaded.
This avoids a flash of unstyled content, which looks especially bad in
browser.html since unstyled content is white and browser.html has a
transparent background.
Closes#9996.

style: Compute damage for text nodes.
They have styles just like elements do.
Allows a dynamic change of `display: none` to `display: inline` to work.

Use lazy_static for HOST_TABLE.
This might change behaviour if the file is changed between Servo startup and
the moment HOST_TABLE is first accessed. I don't think we care.

Compute damage even when incremental layout is disabled
This fixes traversals that use the damage flags to decide which nodes to process, such as `resolve_generated_content`, which was broken in non-incremental mode. r? @pcwalton

Don't re-resolve already-resolved generated content
This fixes#7846, a failure in the "quotes-036.htm" test. Servo lays out this test correctly in its initial layout, but then messes it up in any relayout (whether it's an incremental or full layout).
The problem is that the ResolveGeneratedContent traversal is not safe to run more than once on the same flow. It mutates some GeneratedContent fragments into ScannedText fragments, but leaves others unmodified (in particular, those that generate empty content). The next time layout runs, these remaining GeneratedContent fragments are processed *again* but with an incorrect correct quote nesting level (because some of the surrounding GeneratedContent fragments are gone).
This patch ensures that each GeneratedContent fragment is resolved only once.
