Add a flag field to PP_CompletionCallback to control if the callback should
always be invoked asynchronously on success or error or skipped if the
operation can complete synchronously without blocking. Keep the default
behavior as-is until clients update their code. Bump revisions of all
interfaces that take callbacks as args. Update browser interface function
implementations and C++ layer to force callbacks if sync option is not set.
Change ppapi/tests to run tests involving callbacks with both flag options.
