This also removes the meta viewport support (which was implemented on top), but that also had a single test and is disabled everywhere, so I'm not too concerned, it can be implemented again if / when needed.
This directory now contains third_party software that is vendored into
the Servo source tree. The idea is that it would eventually hold
webrender and other crates from mozilla-central as well with a standard
patch management approach for each.
Replace use of the deprecated RUST_SYMBOL_TO_JSID by SymbolId
<!-- Please describe your changes on the following line: -->
A simple replacement of a deprecated function, according to changes in https://github.com/servo/mozjs/pull/315
That removes the only build warning I saw when doing a clobber.

When turning DOM exceptions into `ErrorInfo` always try to stringify
the JavaScript value, even if it's an object that isn't a `DOMException`
or native exception. This means that exceptions that extend the `Error`
prototype are now stringified. The result is that test output for WPT
global assertion failures is more useful. For instance for the test
include-frames-from-child-same-origin-grandchild.sub.html:
Before:
```
uncaught exception: unknown (can't convert to string)
```
After:
```
uncaught exception: Error: assert_equals: expected 4 but got 3
```
- Mark some instances of unused fields and variables as as allowed,
when they are used for memory management.
- Remove the use of some deprecated function.s

```
The expression `crossOriginIframe.contentWindow.location.href = "new
href"` takes the following steps: (1) Get the setter for `href` by
invoking `[[GetOwnProperty]]` on `crossOriginIframe.contentWindow.
location`. (2) Call the setter, passing `crossOriginIframe.
contentWindow` and `"new href"`. Since the target `Location` is cross
origin, getting the setter succeeds only if the `CrossOriginWritable`
extended attribute is present on the `href` attribute, and it's present.
However, instead of `CrossOriginWritable`, `CrossOriginReadable` was
checked mistakenly.
Since `Location#href` has `CrossOriginWritable` but not
`CrossOriginReadable`, this bug rendered `Location#href` inaccessible
from a cross-origin document.
There are code fragments in `(Method|Attr)Definer.generateArray` that
are much alike. This commit refactors them into a new method of
`PropertyDefiner` named `generateUnguardedArray` (in contrast to the
existing method `generateGuardedArray`).
It's technically safe to do because of `#[repr(transparent)]` and is a
prerequisite of having `ServoJSPrincipalsRef: Copy`, but I guess it's
not worth an `unsafe` block.
Fixes the following assertion from `tests/wpt/web-platform-tests/html/
browsers/origin/cross-origin-objects/cross-origin-objects.html`:
assert_equals(Object.keys(win.location).length, 0,
"Object.keys() gives the right answer for cross-origin Location");
