Added Async HTML Tokenizer
Design: I realized having two different parsers for sync and async was wrong, because the API for both was fundamentally the same. All I needed to do was create another Tokenizer, because `ParseNode` ( representation for nodes which are yet to be created) is used by the TreeBuilder and the Sink, and the `Tokenizer` is the 'lowermost' type concerned with these two types.
Therefore, I created one and placed it in `async_html.rs`, and also created a new Sink which deals with `ParseNode`s. I changed the methods in ServoParser to take an `async` argument too, which decides which Tokenizer will be used. The Tokenizer isn't exactly *async* for now, but this PR separates action creation from execution, which allows the async behaviour to be implemented later. Right now, all actions are executed soon after they are created.
The Sink consists of two Hashmaps, `nodes`, which contains the actual nodes, with the key being their corresponding `ParseNode`'s id, and `parse_node_data`, which contains metadata about the nodes.
It's still a bit rough, (I can't figure out how to deal with `complete_script` and `is_mathml_annotation_xml_integration_point`, along with some other parts I wrote in a hurry), but I believe the overall design is sound. I'd like to hear what you think about it.

Hold stderr lock when using stdout through Console APIs.
This addresses a longstanding source of intermittent test failures where the stderr and stdout outputs get interleaved and the test harness becomes confused.

Avoid panic when reloading a page with mouse event handlers
This PR fixes issue #16057, by nullifying `topmost_mouse_over_target` inside of the `handle_exit_pipeline_msg` method, in case owner document is the same as the pipeline document that is being destroyed.

Testing was done manually, by running `./mach run (-r|-d) "http://localhost:8000/minimal.html" `, where `minimal.html` contains `<div onmouseover="location.reload()" onmouseout="this.clientLeft">hi there</div>`.

This commit also removes the old restyle_hints module and splits it into
multiple modules under components/style/invalidation/element/.
The basic approach is to walk down the tree using compound selectors as needed,
in order to do as little selector-matching as possible.
Bug: 1368240
MozReview-Commit-ID: 2YO8fKFygZI
This patch renames TNode::parent_element to traversal_parent, since it returns
the parent from the perspective of traversal (which in Gecko uses the
flattened tree). It also renames TNode::children to traversal_children
for the saem reason.
We keep parent_element and children functions on TNode to use for selector
matching, which must be done on the real DOM tree structure.

The pref `webgl.testing.context_creation_error` will cause creation of a new WebGLRenderingContext to fail, iff set to true.
Also update test expectation of `context_creation_error.html` to pass.
