implements data-url fetching
Fixes#10165
jdm mentioned of decoupling the, payload loading mechanism to data_loader.rs. So accordingly a `decoder` method has been added to data_loader.

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.

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.

Added a mapping between nodes and stylesheets
Currently a work in progress solution for #10143.
I am not sure how to make the stylesheets() func return a `Ref<Vec<Arc<Stylesheet>>>` or if this way work just as well.
If anyone has any feedback, that would be great.

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.
