Mojo: Beginnings of (local) data pipe tests + more refactoring.

Make the DataPipe methods not take |flags|, to make it more obvious that
dealing with/validating |flags| is the responsibility of the caller.

Also split ConsumerReadData into three methods (read/discard/query),
which parallels what the implementation subclass already had.
