There shouldn’t be (and there currently isn’t) any platform-specific code in Page.cpp.

Removed #if PLATFORM(IOS) where possible.

Why doesn't this all happen via an exitFullscreen() code path? Bad to pollute Document with yet more fullscreen gunk.

Per our conversation. This is now much simpler. WebView and WebPageProxy request exit-fullscreen from  WebVideoFullscreenController and WebVideoFullscreenManagerProxy respectively.

This looks good to me but I am not a WK2 reviewer so someone else will need to r+.

Nit: this can be done in a follow-up patch, but you should NULL-check m_mediaElement here as well.

WK2 part is fine with me, the rest has ericc's review.

Merge these and put the #ifs inside the conditional, maybe?
