possible shorthands matches the linked spec.
Previously substep 5 attempted to serialize the complete shorthand
declaration and substep 6 skipped to the next shorthand only if the
current shorthand was not serialized, but this did not catch empty
serializations. The spec on the other hand specifically says that the
*value* should be evaluated first and if the value is empty substep 6
should skip to the next shorthand - which is what happens now.
To do this required some refactoring which mostly simplifies the code.
Specifically:
- append_declaration_value was refactored so that importance is not
required as a arg (by moving it to the end of append_serialization)
and is_overflow_with_name was removed as an arg also (initially I
refactored it elsewhere, but it turns out it's no longer required at
all - more below). With these changes, append_declaration_value can
be used within the algorithm for to_css to obtain just the value for
substep 5.
- Substeps 7 and 8 of the algorithm become explicit (they were implicit
before) by passing the value, shorthand and importance to
append_serialization.
- serialize_shorthand_to_buffer is no longer required (as the algorithm
serializes the value first instead, as per the spec.
A surprising result of this was that I could also remove a lot of code
handling the special case of the overflow properties serialization. This
is because the overflow's LonghandToCss implementation of
to_css_declared already does the right thing according to the spec - it
writes the single value if both overflow-x and -y are equal, and
writes nothing otherwise - so that the algorithm now skips that shorthand
instead rendering the longhands.
Remove network requests from image cache thread
The design of initiating network requests from the image cache thread was simple, but it makes it difficult to implement image loading that conforms to the HTML specification. These changes make the implementation of HTMLImageElement responsible for network requests for `<img>` elements, and CSS-based images (background-image, bullets, etc.) are requested by the script thread to ensure that the layout thread does not attempt to retain unsafe pointers to DOM nodes during asynchronous operations.

Simplify defining arc ffi types

In support of this goal, the layout thread collects information about
CSS images that are missing image data and hands it off to the script
thread after layout completes. The script thread stores a list of
nodes that will need to be reflowed after the associated network
request is complete. The script thread ensures that the nodes are
not GCed while a request is ongoing, which the layout thread is
incapable of guaranteeing.
The image cache's API has also been redesigned in support of this
work. No network requests are made by the new image cache, since it
does not possess the document-specific information necessary to
initiate them. Instead, there is now a single, synchronous
query operation that optionally reserves a slot when a cache
entry for a URL cannot be found. This reserved slot is then
the responsibility of the queryer to populate with the contents
of the network response for the URL once it is complete. Any
subsequent queries for the same URL will be informed that the
response is pending until that occurs.
The changes to layout also remove the synchronous image loading
code path, which means that reftests now test the same code
that non-test binaries execute. The decision to take a screenshot
now considers whether there are any outstanding image
requests for layout in order to avoid intermittent failures in
reftests that use CSS images.
Update WR (inset box shadow fix, border-image support).
I have a follow up PR for Servo that uses the new border-image
APIs, but I'll land that separately, so that we don't delay
landing the WR update itself.

Add ImmutableOrigin to allow for serializing origins
<!-- Please describe your changes on the following line: -->
This PR adds a serializable type `ImmutableOrigin` and a non-serializable type `MutableOrigin`. The immutable type represents an origin with `null` domain, and the mutable type represents an origin with a mutable domain. This separation is needed for implementing setting `document.domain`.
