    [dri2] Add tail pointer to reemitDrawableInfo callback.
    
    When the DRI doesn't parse the event buffer for a while, the X server
    may overwrite data that the driver didn't get a chance to look at.  The
    reemitDrawableInfo callback requests that the X server reemit all info
    for the specified drawable.  To make use of this, the drive needs to know
    the new tail pointer so it know where to start reading from.

    [dri2] Optimize event parsing to skip obsolete events.
    
    This also fixes the problem where the X server does multiple resizes before
    the DRI driver gets the events.  The obsolete buffer attach events then
    reference already destroyed buffer objects.
