inline placement of floats.
Otherwise, the heuristics can pass even when there are no floats,
causing block formatting contexts to be speculated to be flowing around
floats that don't exist!
Closes#10237.
This is the first part of #10185. More to follow. I have built this locally with both servo and geckolib without errors; let's see if it succeeds on all platforms as well.
Allow setting preferences to false in WPT tests
First patch to servo - apologies if I did something stupid :)
This is a fix for #10161. I have squashed the commits into one.

Added ability to randomly kill pipelines to the constellation.
Added flags:
* `--random-pipeline-closure-probability`: probability of each event triggering a forced exit of a randomly chosen pipeline.
* `--random-pipeline-closure-seed`: seed to use for the RNG (to remove a source of intermittent failure).
These are designed for testing the hardness of the constellation.

Add Http Global State Object
This adds a new HttpState object which holds common http state(#10175). This reduces the amount of work that is required to add extra things to the Http state.
The HttpState object currently holds:
```
hsts_list: Arc::new(RwLock::new(HSTSList::new())),
cookie_jar: Arc::new(RwLock::new(CookieStorage::new())),
auth_cache: Arc::new(RwLock::new(HashMap::new())),
```

Highlight selected text in input fields
Fixes#9993. This does not yet allow stylesheets to set the selection colors; instead it uses a hard-coded orange background and white foreground.

layout: Rewrite the block formatting context/float inline-size speculation code.
The old code tried to do the speculation as a single bottom-up pass
after intrinsic inline-size calculation, which was unable to handle
cases like this:
<div>
<div style="float: left">Foo</div>
</div>
<div>
<div style="overflow: hidden">Bar</div>
</div>
No single bottom-up pass could possibly handle this case, because the
inline-size of the float flowing out of the "Foo" block could never make
it down to the "Bar" block, where it is needed for speculation.
On the pages I tried, this regresses layout performance by 1%-2%.
I first noticed this breaking some pages, like the Google SERPs, several
months ago.

layout: Allow floats to have negative ceilings due to negative margins.
This fixes `margin-collapse-104.htm`, which is currently accidentally
passing due to lack of #10085. When that PR lands, then that will become
a representative test case.
