Not much changed in the interface: - CDM initialization takes a use hardware codecs arg, we pipe this through, but don't do anything more with it in the clearkey CDM. - The CDM should call the hosts OnInitialized() when it's initialized. This is done is now done in the clearkey CDM once the session management is ready, as that is the last thing done during init. Aside from the above, it's just updating interface usage. While the new CDM interface adds support for different encryption schemes, this is not handled here and will be done in follow up bug 1516673.
