ff_avfilter_graph_check_validity() ff_avfilter_graph_config_links() ff_avfilter_graph_config_formats() and move their declaration to internal.h. These functions are never used in application code, so it is better to consider them internal functions, this can be changed later if necessary. Simplify API.
