OK. I did a version of this that uses lambdas, but I guess this is more elegant.

r=me, only if you fix the problem with setAsset

> Source/WebCore/platform/graphics/avfoundation/objc/MediaPlayerPrivateAVFoundationObjC.mm:3189
> +    std::function<void()> function;

I think we decided to standardize on void () with the space. Anders did a patch recently about making this consistent.

> Source/WebCore/platform/graphics/avfoundation/objc/MediaPlayerPrivateAVFoundationObjC.mm:3221
> -            function = WTF::bind(&MediaPlayerPrivateAVFoundationObjC::setAsset, m_callback, RetainPtr<NSArray>(newValue));
> +            function = std::bind(&MediaPlayerPrivateAVFoundationObjC::setAsset, m_callback, newValue);

This introduces a bug. Nothing will retain/release the value and it could be deallocated by the time it runs on the main thread. Need to cast to some kind of RetainPtr.

Uses RetainPtr<id> for ::setAsset().
