Only allow animation-timing-function in @keyframes
CSS animations used to erroneously indicate that 'animation-play-state' is permitted in @keyframes. It is not and it'ss non-sensical to allow it there. This mistake was faithfully transferred into Servo code (although we also make 'animation-timing-function' which is what the spec text meant to say).
The spec has [been updated](adeb3434c5) and so we should update the Servo code accordingly.

use DisplayListBuilder::with_capacity
DO NOT MERGE until https://github.com/servo/webrender/pull/1399 has landed in Servo.
Previously webrender was reserving 1MB of space for each display list (empirically pages weighed between 100k and 10MB when I implemented this). This was problematic for gecko because they used webrender differently. This just brings Servo back to where it was.

This makes us hit some assertions in Gecko.

Make network error messages more specific
Instead of having a bogus "Network error" string, we extract the NetworkError struct from the Response and send it back to FetchResponseListener.

is permitted in @keyframes. It is not and is non-sensical to allow it

The spec has been updated[1] and so we should update the Servo code
accordingly.
[1] adeb3434c5
Update WR (switch to new text-decorations API in WR).
This only makes use of the "Solid" text decoration type, which
matches the existing support. WR now supports dotted, dashed
and wavy text decorations, but supporting those will need some
extra work in Servo to pass through the correct values.

Store raw string for prop decl in @supports
This fixes the serialization issue of `@supports` rule that whitespaces are not preserved like in other browsers.
It makes the work a bit redundant (the property name and colon is parsed twice), but I suppose this isn't a big deal.
