The C++ interface should take care of reference counting for you correctly. If
it doesn't, it's a bug in the C++ wrapper
(ppapi/cpp/private/content_decryptor_private.cc). You can either do
ReleaseResource there, or add a PassRef constructor to pp::BufferDev (see
pp::Resource).

Added a PassRef ctor to pp::BufferDev.

   return true;
