Crashes are probably due to libwebrtc not defining NDEBUG while WebCore does.
Then classes from libwebrtc included/instantiated within WebCore no longer have the same definition, size...

I like this.  Let's split it up and do it cleanly.

> Source/WebCore/ChangeLog:10
> +        * platform/mediastream/libwebrtc/VideoToolBoxEncoderFactory.cpp:

This change is not in this patch.

> Source/ThirdParty/libwebrtc/Configurations/Base.xcconfig:75
> +DEAD_CODE_STRIPPING_normal = YES;

This cuts almost 1MB of code from release libwebrtc.dylib!

> Source/ThirdParty/libwebrtc/Source/webrtc/sdk/objc/Framework/Classes/videotoolboxvideocodecfactory.cc:40
> -    return new H264VideoToolboxEncoder(codec);
> +    return CreateSupportedVideoEncoder(codec);

This change is unrelated to the rest of the changes in this patch.  The other changes should be in a separate patch titled something like "Strip dead code from release libwebrtc.dylib"

Well, this change was triggering crashes.
The fact that it no longer crashes on EWS show that  we have a fix there.

OK to split it now that the fix is validated.
