This allows WebRender to correctly render complex clipping regions that
can be reduced to single rounded rectangles. WebRender still can't
render rounded rectangles with arbitrary intersections yet, but this
allows it to handle many more cases.
Closesservo/webrender#241.
We currently get tons of useless backtraces clogging up the output when we have a panic cascade. This adds a handler that outputs a single line when a thread panics due to a sender or receiver hanging up, since this is almost always due to a panic cascade.
Removed panicking when frame or pipeline lookup fails.
Removed the methods `pipeline(id)`, `pipeline_mut(id)`, `frame(id)` and `frame_mut(id)` from constellation, which panicked when the table lookup failed.
The panics were causing race conditions, e.g. visiting google.com and resizing the page would cause a panic, most likely due to an iframe being added and removed, with the `DOMLoad` event arriving after the iframe had been removed, causing a panic.
This patch fixes#10017 and #8769 (although in non-webrender builds there's now a different panic, see https://github.com/servo/servo/issues/10017#issuecomment-198160200).
There are a few `TODO` items in the initial commit, for cases where it's not completely obvious what to do in the case of failure.

In WebRender mode, we were sending two mouse move events: one with the
proper coordinates and one with the wrong coordinates, because of
incorrect fall-through. The script task would usually (but not always,
depending on timing) ignore the first event in favor of the second
event, resulting in incorrect mouse move event coordinates in most
cases.
Closes servo/webrender#238.
Closes#10298.
Update webrender to master
I'll rebase #10224 against it.
Sorry for the blocking of #10224, I expected it to be reviewed way sooner, my fault for landing breaking changes.

Include square brackets for IPv6 addresses in Document::domain.
The specification changed out from under us.
It's unfortunately impossible to write a test for this right now.

Implement ::selection pseudo-element
It only supports `color` and `background`, for now, but it shouldn't be hard to add more properties (like text-shadow).

Replace any uses of .send().unwrap() by .send().unwrap_or_else().
This is part of the effort to harden the constellation (#10124), in this case against panics caused by channel send.

Reduce size of layout::fragment::Fragment struct
This reduces the size of the SpecificFragmentInfo enum from 48 to 24.
