@jdm This is going to require some effort to merge my changes with other recent changes to `ParserContext`. Because of that I would appreciate a quick sanity check before I put the time into performing the merge.
For example, should I store the `offset` as a u64, or should it be an Option?

This PR aims to solve issue #15729. I tried to follow the recommendations there as much as possible.
This is my first attempt at contributing to Servo, so this will probably need a lot of input, although I'm eager to make it as polished as possible.
- The base inaccuracy issue seems solved, as can be easily verified with the `console.log` based example in the issue.
- Very basic unit tests were added.
I have doubts mainly about the right way to represent these new enum variants for the various length units:
1. With new enum variants in `NoCalcLength` *and* newtypes (current solution)
2. With a `NoCalcLength::Absolute` variant that contains a new `AbsoluteLength` enum, but without newtypes
3. Same as solution 2 but with newtypes
- I mostly cared about unit tests until now but will investigate other types of tests
- Tests to check the clamping
- Write a proper commit message
Thanks for your time and feedback :)

issue https://github.com/servo/servo/issues/15252
The primary goal of this PR is to add add a generic trait method that returns a void ptr.
In addition to that change, I made the casting explicit in `components/script/dom/bindings/callback.rs` and `components/script/dom/promise.rs`. I did not use the new trait method because `AddRawValueRoot` is not looking for a `c_void`. It's looking for `std::os::raw::c_char`.
```rust
pub fn AddRawValueRoot(cx: *mut JSContext, vp: *mut Value,
name: *const ::std::os::raw::c_char) -> bool;
```
So I replace the `as *const _ ` with a more specific cast.

Fix#16165.
Also, it turns out that the CSSFontFaceRule IDL specified in the css-fonts spec is not web-compatible. Instead browsers implement a .style attribute like in CSSStyleRule: https://github.com/w3c/csswg-drafts/issues/825
This in turn requires preserving data about which descriptors were set or not (distinguishing unset from set to a value that happens to be the initial value), so this commit also makes every field `Option<_>`.

Instead of unwrapping `new_with_jsobject` result, `ImageData::new` will just pass the error along.
It required tweaking `canvasrenderingcontext2d` as it no longer needs to assume the result is `Ok`.

<!-- Please describe your changes on the following line: -->
Before this PR, every object reflected in CSSOM is in `Arc<RwLock<_>>` to enable safe (synchronized) mutable aliasing. Acquiring all these locks has significant cost during selector matching:
* https://bugzilla.mozilla.org/show_bug.cgi?id=1311469
* https://bugzilla.mozilla.org/show_bug.cgi?id=1335941
* https://bugzilla.mozilla.org/show_bug.cgi?id=1339703
This PR introduce a mechanism to protect many objects with the same `RwLock` that only needs to be acquired once.
In Stylo, there is one such lock per process (in a `lazy_static`), used for everything.
I non-Stylo Servo, I originally intended to have one such lock per document (for author-origin stylesheets, and one per process for user-agent and user sytlesheets since they’re shared across documents, and never mutated anyway). However I failed to have the same document-specific (or pipeline-specific) `Arc` reachable from both `Document` nodes and `LayoutThread`. Recursively following callers lead me to include this `Arc` in `UnprivilegedPipelineContent`, but that needs to be serializable. So there is a second process-wide lock.
This was previously #15998, closed accidentally.

I think these properties are generally rare enough that they're not worth adding 8 bytes of memmove overhead on every PropertyDeclaration. There are a _lot_ of 24-byte properties though, so I think that's probably a good sustainable level.

Current browsing context accessor in `Document` unwraps the browsing context `Option` which prevents document to handle correctly the case when there is no browsing context.
This is the reason servo panics with `session-history.max-length=1` (https://github.com/servo/servo/issues/15877).
As it is my first contribution, I added a `safe` method to retrieve the browsing context rather than change the existing method, but I am happy to change if you think this is the right approach. I did not as well replace all existing method call to the `safe` method, to focus on fixing the issue.
If someone can give me a bit of guidance for the test, I will try to contribute one.
