           Summary: suggest needKey report codecs+key system supported by
                    the UA

It is a little complex for JS to test the UA using canPlayType() for many times
to determine the key system.

I propose we just use needKey event to report the supported codec+key system
pairs list to app, let app choose one key system among it, this will reduce the
times of call to the UA for testing key system using canPlayType, and avoid
extension of canPlayType.

What do you think about it?
