Prefix with "ff_" the functions: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 neverused in application code, so it is better to consider them internal...
Implement ff_get_ref_perms_string() and use it for tracing.

Rename ff_dprintf_picref() to ff_dprintf_ref().
The function is going to be used to represent also audio data.

Rename AVFilterPicRef to AVFilterBufferRef.
The struct is going to be used for storing audio buffer references aswell, and the new name is more generic.
