Fix the "get the parent" loop when dispatching event (fixes#6733)
The DOM specification says:
> A document's get the parent algorithm, given an event, returns null
> if event's type attribute value is "load" or document does not have
> a browsing context, and the document's associated Window object
> otherwise.

Validate MIME pattern checking
The MIME detector for a HTML file contains an additional byte in the mask. While it doesn't hurt, it is not used in the byte matching code (since it is zipped with the `pattern` iterator).
I'm not clear how to test this within the `servo` code. The fix doesn't change any externally visible behavior. A test to validate the `ByteMatcher` structures would require the private ByteMatcher structures to be visible to the test. I could use a sub-module, as described at https://doc.rust-lang.org/book/testing.html#the-tests-module but this pattern doesn't appear anywhere else in the `servo` code.

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...)

This adds a size to the test webp file, since the error fixed occurs
when the test object is the same length as the matched pattern, and
is not equal to the pattern.
Add methods to move ByteStrings underlying bytes
Add methods to move the underlying `Vec<u8>` for `ByteString`.
I saw this as at least two methods. One to "move and replace with and empty Vec<u8> (`bytes`), and one to take ownership of the whole object (`own_bytes`). I typically also don't like adding methods with out unit tests. If you think they're unnecessary, just let me know.
As always, please let me know if you have any comments, critiques, or nits!
Fixes#9655

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.
