when hlsenc use flag second_level_segment_index,
second_level_segment_size and second_level_segment_duration,
the rename is ok but the output filename always use the old filename
so move the rename operation after the close the ts file and
before open new segment

Fixes ticket #6075.

Hopefully fix compilation with suncc.

Fixes decoding the sample from ticket #6072 with ffmpeg.

avfilter_graph_request_oldest() does work that should be done by
either the filter or the application.

The principle of this function, calling ff_request_frame() from
outside the filter was always shaky. This version is less elegant
since it requires making special cases for each filter, but it
is more robust since it no longer calls ff_request_frame()
directly without notifying the filter.

Eventually, avfilter_graph_request_oldest() will be deprecated
for a function to just run the graph.

ff_request_frame_to_filter() and ff_filter_frame_to_filter()
are only used in avfilter.c.

Having two different functions allows to have stricter tests
and detect errors earlier.

It does not change anything for the existing filters and makes
better code fatrorization when future code will use the utility
functions.

Unlike av_frame_is_writable(), it uses the link's alloc callback,
making direct rendering possible.

The code comes from ff_filter_frame_framed(), moved with mostly
trivial changes.

Also introduce libavfilter/filters.h for all functions needed
to implement filters.

av_buffersink_get_frame_rate() did already exist; its argument becomes const.

The names are only used for technical output and debugging.
Make them similar to C identifiers for easier quick reading
of debug dumps.
