        staging: vc04_services: remove vchiq_copy_from_user

        The vchiq_copy_from_user function is not portable
        and is consider "bad practice."  Replace this function
        with a callback based mechanism that is passed downward
        on the stack.  When it is actually time to copy the data,
        the callback is called to copy the data into the message.

        This callback is provided internally for userland calls
        through ioctls on the device.

        NOTE: Internal clients will need to be modified to work
        with the new internal API.

        Test Run:
        vchiq_test -p 1
        vchiq_test -f 10

        Both tests pass.

        Internal API Changes:

        Change vchi_msg_queue to:
        int32_t
        vchi_msg_queue(VCHI_SERVICE_HANDLE_T handle,
                       ssize_t (*copy_callback)(void *context, void *dest,
                                                size_t offset, size_t maxsize),
                       void *context,
                       uint32_t data_size );

        Remove:
        vchi_msg_queuev_ex
        vchi_msg_queuev

        These functions were not implemented anyway so no need to fix them. It's
        easier to just remove them.
