As part of the normalization process for WebExtension API calls, we need to
extract and validate the full set of value properties (including properties
X-rays would normally deny access to) from cross-compartment objects. This
currently involves waiving X-rays, enumerating property descriptors, and
unwaiving X-rays - all through X-ray wrappers and waivers - and generating a
lot of expensive and short-lived wrappers in-between.
This helper reads out the list of safe properties from within the object's
compartment, and then copies them over to an object in the target compartment,
without any X-ray overhead, or any unnecessary intermediate wrappers or
compartment switches. It cuts about 40% off the overhead of our normalization
code.

In the code that I'm profiling, the XPC WrappedNative overhead of calling
these functions adds up to about a quarter of the time spent executing the
code. The overhead of the WebIDL versions is negligible.

There is no reason that SetTextRangeStyle is defined at nsISelectionPrivate. Also, SetTextRangeStyle isn't scriptable, and is called from CompositionTransaction::SetIMESelection only. So we should move this to Selection.

The libaom av1 decoder will return 16 bit per channel
aom_image_t structures with only 8 significant bits.
Detect this case and use the mSkip fields of PlanarYCbCrImage
to handle the extra data instead of allocating and performing
an extra copy to obtain the necessary 8 bit representation.

The libaom av1 decoder can return high bit depth frame
data now. Handle those frames by downsampling them
to 8 bits per channel so they can be passed to our
normal playback pipeline.

The virtual call to this method shows up in profiles, and therefore
would be nice to avoid if possible. We can do that by making
nsIWeakReference hold the weak reference itself and therefore
implementing a non-virtual QueryReferent method.
1. Adding new checks in ConstructorChromeScript.js to checking the top level
document's principal information.
2. Adding a new test testCrossOriginTopLevelPrincipal in
test_constructor.html to testing the topLevelPrincipal attribute under
cross origin situation.
3. Removing some useless mochitest browser-chrome testcase.
Getting the top level document's principal when constructing PaymentRequest,
then sending it to chrome process and saving it in nsIPaymentRequest.
Creating a new readonly attribute nsIPrincipal topLevelPrincipal in
nsIPaymentRequest for UI to query the top level document's principal
information.

In the patch2, we would honestly return the value of playback rate.

According to [1], we should only dispatch event "ratechange" when playbackRate or
defaultPlaybackRate attribute has just been updated. In these tests, they didn't
change the playbackRate or defaultPlaybackRate, we should not expect for the
"ratechange" event.

According to [1], we should return NotSupportedError for the negative playback rate.
