nit: maybe "for CDM initialization". Same with the struct name, though I don't
have a great name.

PP_CdmConfigurationFlags?

Done.

FYI, dmichael@ I'm going to rip out the CanChallengePlatform() PPAPI in favor of
this. There's just no way for us to use this value asynchronously in a clean

FWIW, if you're invoking from a background thread, you can use
PP_BlockUntilComplete to make it a synchronous call. This is probably okay too.
