Don't re-resolve already-resolved generated content
This fixes#7846, a failure in the "quotes-036.htm" test. Servo lays out this test correctly in its initial layout, but then messes it up in any relayout (whether it's an incremental or full layout).
The problem is that the ResolveGeneratedContent traversal is not safe to run more than once on the same flow. It mutates some GeneratedContent fragments into ScannedText fragments, but leaves others unmodified (in particular, those that generate empty content). The next time layout runs, these remaining GeneratedContent fragments are processed *again* but with an incorrect correct quote nesting level (because some of the surrounding GeneratedContent fragments are gone).
This patch ensures that each GeneratedContent fragment is resolved only once.

Add the scrollWidth and scrollHeight extensions to the element interface
Add the `scrollWidth` and `scrollHeight` extensions to the element interface. My goal was to create a method that encompassed getting `scrollWidth`, `scrollHeight`, `scrollTop`, and `scrollLeft`.
I also noted that `clientHeight` and `clientWidth` to not handle the root element and the body element correctly.

Fix work list order after split_line_at_last_known_good_position
This fixes a bug in line splitting caused by the following actions when `LineBreaker::split_line_at_last_known_good_position` is called:
1. Push some number of previous fragments onto the front of the work list.
2. Push the current fragment back onto the front work list.
This resulted in the work list being out of order. The correct order is action 2 followed by action 1. Fixes#9830. r? @pcwalton

Moved synthetic_click_actiavtion out of Activatable trait so it can be
called by all elements (not just activatable). Calls appropriately
from click. Also updates the isdisabled check in click to check for all
types of elements

Add Tests For Asynchronous Fetch Calls With Filtered Responses
I've added two tests using async_fetch intended to create filtered responses. I caught and fixed a bug where waiting for response.body to be completed would never pass for Opaque or OpaqueRedirect, since their response.body is always `Empty`.
As always, I'd appreciate review and feedback! I don't plan to write new tests, but I will gladly patch up any gaps in the current tests.

Set response.body Asynchronously In Fetch
Following having finished making Fetch asynchronous, response.body should be set asynchronously, since it's the major goal of calling Fetch. So far, I've made the body wrapped in Arc<Mutex<>>, and I've wrapped a new thread around the part where it's set. I've also discovered that the fetch_async function makes step 8 of Main Fetch obsolete, and I've commented it appropriately.
I'm currently having a hard time with the thread for setting response.body, though. @jdm suggested I have the body set continually, block by block, but my implementation for that runs so slow that I can't finish running my fetch test suite in reasonable time. @KiChjang pointed out that a lot of the lag is due to how response.body currently stores everything inside a Vec. Changing the storage container seems to be both necessary and beyond the scope of the time I have to work on this.

This fixes a bug where partially loaded content is displayed to the user
before it should be, usually before stylesheets have loaded. This commit
supresses reflows until either FirstLoad or RefreshTick, whichever comes
first.
Unfortunately, hit_test and mouse_over did not do reflows if they were
necessary, and so by suppressing the initial spurious reflows, these
methods started to panic without a display list to query. This patch
also transforms these into queries similar to the other existing
queries.
script: Fix MouseOver handling
Now we only query for the topmost node, and apply the hover state to all
of the parent elements.
This fixes things like #9705, where the hover state was applied only to
the children.
This also makes us more conformant with other browsers in the case of
taking in account margins and paddings.
For example, prior to this PR, when your mouse was over the inner
element, in the bottom part, `hover` styles didn't apply to the parent.
```html
<style>
div {
padding: 10px;
margin: 10px;
height: 15px;
background: blue;
}
div:hover {
background: red;
}
</style>
<div>
<div></div>
</div>
```
Fixes#9705

Table border-collapse fixes
Two related fixes for border-collapse:
* Fix border collapsing across table-row-group flows
This fixes the border-end calculation for table rows whose borders are collapsed with rows in different rowgroups. The border collapsing code now uses an iterator that yields all the rows as a flat sequence, regardless of how they are grouped in rowgroups. It gets rid of `TableRowGroupFlow::preliminary_collapsed_borders` which was never correct. (It was read but never written.)
This may fix#8120 but I'm not 100% certain. (I haven't managed to reproduce the intermittent failure locally, and my reduced test case still fails but in a different way.)
* Fix confusing `push_or_mutate` API
This fixes a bug when recalculating border collapsing for an existing table row. The bug was caused by using `push_or_mutate` which has no effect if there is already a value at the specified index.
The fix switches incorrect `push_or_mutate` calls to use `push_or_set` instead. It also renames `push_or_mutate` to `get_mut_or_push` which I think is a less-confusing name for this method.

Make Fetch Protocol Asynchronous
I'm working on making it possible to run Fetch Asynchronously, as required for some steps, such as Main Fetch. It looks like somebody has already laid some groundwork for that, with a AsyncFetchListener trait and two async fetch functions defined, which I'm building on top of.
So far, as a sort of proof of concept, I've written a test to asynchronously retrieve a fetch response, which uses a simple function to check if the fetch response is complete or not. I'd like to be checked if I'm on the right path, to see if I need to rework anything so far, and what my next step can be.
