"javascript:" urls: execute in correct global scope
<!-- Please describe your changes on the following line: -->
#### Summary
This pull request makes `javascript:` urls execute in the correct global scope.
#### Example
```html
<script> var x = 4; </script>
<!-- this branch: logs "4" -->
<!-- master: undefined variable error -->
<a href="javascript:console.log(x)">link</a>
```
#### Questions
I'm new to servo and rust, so I'm unsure about these changes. In particular:
* What's the appropriate place to evaluate the js?
* I moved it to `handle_navigate`, but I'm not sure if this will catch all occurrences of `javascript:` urls. I also don't know if this will execute in the correct thread and the correct window.
* What should I do with the result of the js evaluation?
* I just ignored it. The previous behavior displayed it as the content of a new page load.

- generalize the eval_js_url function so it can be called from
multiple places.
- call it in htmliframeelement.
- if the js eval results in a non-string result, then it won't
navigate to a new page, so don't block on the new page loading.
Problem:
After aborting on a 204 or 205 status code, you could no longer
follow links on the page.
Cause:
`constellation.rs` ignores new LoadUrl requests since the aborted
one is in its `pending_changes` list.
Solution:
Send a message to constellation that lets it clean up its
`pending_changes` list.

First step toward iOS Support
This mostly prevents Gaol/sandboxing to be used during compilation.
There are a number of issues with : `expat-sys`, `servo-freetype-sys`, `fontsan`, `heartbeats-simple-sys`, `mozjs_sys`.
Also modified `components/script/dom/navigatorinfo.rs` in order to add iOS.
```rust
#[cfg(target_os = "ios")]
pub fn Platform() -> DOMString {
DOMString::from("iOS")
}
```

make sure proper frame tree is sent when iframes change
We ran into a hittest issue because the frame tree was not correctly updated after #17425.
The frame tree should be updated on tab change (via send_frame_tree) or when the frame sub tree changes and it's the active one (via update_frame_tree_if_active).

always call new_pipeline() before add_pending_changes()
There are some changes we want to make in `add_pending_changes` which require pipelines to be registered in self.pipelines.

Separate waking the event loop, from communicating with Compositor
<!-- Please describe your changes on the following line: -->
@paulrouget first step of #15934, Glutin only for now, please take a look...
If this makes sense, I will also update the code for ports other than Glutin...
One question: one do I add the `warn!` macro to `servolib`? Also perhaps we would also want to add `box`, since I had to switch to using `Box::new`...

I ran some tests at random from the `navigating-across-documents` folder, and they are passing.
