In the case where we accumulate transform:none onto decomposed matrix for
iteration composite whose iteration count is over 2, we pass zero
other_portion and self_portion which is over 1.0. We should care about the
case.
Add support for having two separate parent styles. Fixes gecko bug 1382806.

This is needed for ::first-line support. See https://drafts.csswg.org/css-pseudo-4/#first-line-inheritance
This PR doesn't quite implement what the CSS spec draft says right now. It implements what Gecko does, which is what an earlier draft said.

Cleanup @font-face rule constructor
Passing SourceLocation into constructor instead of assigning
immediately after construction cleans up the code and helps to
prevent leaving an invalid SourceLocation in the future.

The concept of inherited style is about to get a bit more complicated, and this
will prevent consumers from doing it wrong.
Part 1 of Gecko bug1382806. r=emilio
Add message suffixes to stylo error reports.
This is the Servo-side part of https://bugzilla.mozilla.org/show_bug.cgi?id=1381137. This allows us to add the "Declaration dropped" or "Skipped to next declaration" messages after relevant CSS errors that are reported.

style: Don't skip computation of pseudo-elements of display: none elements
We have optimizations to avoid doing selector-matching when the style attribute
changes, so, given you can toggle the display property and the pseudo-elements
will suddenly become effective, we can't really skip them.
Furthermore, we assume that if an element has an ElementStyles, they're
up-to-date and we can use them for getComputedStyle, so it's pretty easy to
prove that we do the wrong thing when calling getComputedStyle with a
pseudo-element on a display: none root.

selectors: Fix note_next_sequence.
Selector-matching can backtrack when looking for ancestor combinators, so we
can't just arrive there once and forget.
Also, there was a further problem before this patch, which was that
note_next_sequence was called _before_ checking whether all simple selectors
matched, so the sequence you could get there is just wrong.

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.
