Bryce Van Dyk 5aecaa0a28 Bug 1516669 - Update gmp-clearkey to use CDM10 interface. r=cpearce
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.
