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")
}
```

stylo: Bug 1387990 - Fix the interpolation of 2d matrix.
Write a 2d matrix decomposition for Gecko, so the visual results and test results
could match those in Gecko. In long-term, we should let Gecko follow the spec, so we
can drop the redundant implementation.

The implementation of 2d matrix decomposition in Servo matches that in
spec, but its result is really different from that in Gecko, so the
visual results on the main thread and on the compositor thread are
really different and we got many test failures. Therefore, let's write a
different algorithm of decomposition of 2d matrix for Stylo, and keep
the original one for Servo.
The output of new implemented 2d matrix decomposition is a Decomposed3DMatrix,
so we can reuse the interpolation and re-composition code. (Just like
what we do in Gecko.)
Don't cache style data if the element has running animations.

Move fast checks into earlier Travis task.
This allows quicker feedback about whether the manifest needs updating; otherwise it has to wait until all builds and tests are complete.

style: Move the StyleSheetSet into the Stylist.
This will allow tracking whether there have been only additions to the
stylesheet set, and in that case don't destroy and completely rebuild the
invalidation map.
This is on top of #18143.

Bindgen bitfield enums don't work as return values with the Linux 32-bit ABI at
the moment because they wrap the value in a struct.
This causes the Rust side to believe the caller will pass along space for the
struct return value, while C++ believes it's just an integer value.

Also add a few comments and similar about pending invalidation work, and avoid
passing a device in script, since the work it performs scanning the stylesheet
is just thrown away in the `flush_without_invalidations` call.
This will allow tracking whether there have been only additions to the
stylesheet set, and in that case don't destroy and completely rebuild the
invalidation map.
