[gnome-builder/wip/libide] libide: add stub implementation for ide_buffer_get_line_flags()

    libide: add stub implementation for ide_buffer_get_line_flags()
    
    This function will eventually track the changes in a buffer based on the
    response from the Vcs. Doing so will give us a bit better abstraction
    over the current git implementation.
    
    We'll probably implement the lookup hash independently though, so it can
    be resused based on diff callbacks from the VCS implementation.
