glutin: Close the window if the event stream is closed.
Otherwise we can end up infinitely spinning for no good reason.
This happened today to me. Obviously the underlying situation is also buggy, but this seemed like a more sane behavior compared to infinitely spin waiting for a never-arriving event.

Switch glutin to use the crates.io version of osmesa-sys to remove a duplicate
<!-- Please describe your changes on the following line: -->
This removes the use of a git reference to osmesa-sys in glutin, to use the crates.io one with the same version that is already used in servo:
fabrice@fabrice-ThinkPad-X260:~/dev/servo/components/servo$ cargo tree -i -p osmesa-sys
error: There are multiple `osmesa-sys` packages in your project, and the specification `osmesa-sys` is ambiguous.
Please re-run this command with `-p <spec>` where `<spec>` is one of the following:
https://github.com/daggerbot/osmesa-rs#osmesa-sys:0.1.2https://github.com/rust-lang/crates.io-index#osmesa-sys:0.1.2

incremental restyle: Introduce StylingMode and deprecate explicit dirtiness
This is another chunk of work to move us toward the new incremental restyle architecture.
Eventually, we'll make a fine-grained decision at each node about what style to recompute based on the RestyleHint on the node data (along with other things). For now, we use the existence of RestyleData as a coarse-grained approximation of this.

Remove old rendering backend.
This removes paint threads, rust-layers dependency, and changes
optional webrender types to be required.
The use_webrender option has been removed, however I've left
the "-w" command line option in place for now so that wpt
runner can continue to pass that. Once it's removed from there
we can also remove the -w option.
Once this stage is complete, it should be fine to change the
display list building code to generate webrender display
lists directly and avoid the conversion step.
