Dirty elements whose selectors are affected by sibling changes
This fixes incremental layout of nodes that match pseudo-class selectors such as :first-child, :nth-child, :last-child, :first-of-type, etc. Fixes#8191 and other intermittent layout bugs.
This code is based on the following flags from Gecko:

Depends on servo/rust-selectors#71. r? @SimonSapin
There are a couple of TODO items in this commit, but I'd appreciate feedback on the general approach before I finish it up. (Also, if someone who knows more than I do could give some advice about atomic orderings...)

Add WebRender integration to Servo.
WebRender is an experimental GPU accelerated rendering backend for Servo.
The WebRender backend can be specified by running Servo with the -w option (otherwise the default rendering backend will be used).
WebRender has many bugs, and missing features - but it is usable to browse most websites - please report any WebRender specific rendering bugs you encounter!

Ensure when calculating font metrics that the total line height matches requested line height.
This fixes rounding accuracy issues that could result in layout producing results off by a small number of Au.

CORS Preflight Logic Fix
Fix check to set flag if any header is not a simple header, rather than only if all
headers are simple headers.
Fix failing tests to allow merge in advance of @nikkibee's changes
as per @jdm's direction via IRC.

Fix a broken reftest.
The strong element has a different font weight by default. This means that the line height
is slightly different from the ref test. In normal Servo this doesn't matter due to how the
default snapping works.
However, in both WebRender and Firefox, this results in the reftests being one pixel different.
Setting the font weight to be normal makes the reftest pass in Servo, WebRender and FF.
