    radeon: add correct flushing for direct rendered

    this is a port of 69d65f9184006eac790efcff78a0e425160e95aa from the Intel
    driver.

        Submit batch buffers from flush callback chain

        There are a few cases where the server will flush client output buffers
        but our block handler only catches the most common (before going into
select
        If the server flushes client buffers before we submit our batch buffer,
        the client may receive a damage event for rendering that hasn't
happened yet

        Instead, we can hook into the flush callback chain, which the server
will
        invoke just before flushing output.  This lets us submit batch buffers
        before sending out events, preserving ordering.
