avfilter_default_filter_name() is supposed to access an AVFilterContext
struct, if used with a private struct it will cause a crash since it will
access fields which are non defined in the private struct.
The function is modelled after av_default_item_name(), and will print the
name of the instance filter if defined, otherwise the name of the filter.
This allows to show the instance name in the log, which is useful when
debugging complex filter graphs.
The old implementation, upon receiving a frame on the main
input, would request an overlay frame if necessary. This could
generate an infinite recursion, off-by-one frame mismatch and
other harmful effects, especially it the split filter is present
upgraph.
The new implementation uses the linear approach: it uses two
buffer queues for frames received out of turn and forwards
request_frame calls to the input where a frame is necessary.

Link properties have to be checked after config_props() is called to
make sure everything is sane, so the default config_props() for output
links was redundant.
Remove now empty defaults.c
