Jump to the common release code in case of failure.

If the stats are printed when request_frame on the input
returns EOF, then they are never printed if the filter is
not flushed, in particular when using the -t ffmpeg option.

By default, fps selects frames near PTS 0, 0.5, 1.5, 2.5, etc.
With round=down, it selects the frames near PTS 0, 1, 2, 3, etc.

We don't have a text encoder yet, so this commit makes automatic
encoding working with srt output.

The SRT format should never have outputted CODEC_ID_SRT packets in the
first place: SRT is a subtitle format containing SubRip text markup
events. The timing information is part of the format, not the codec, and
thus CODEC_ID_SRT should not exist.

Creating packets with the timing information within the payload only
leads to problem (such as remuxing with timing alteration not working),
especially when the SubRip markup is being used in container like
Matroska in addition to this standalone SRT format.

The main reason the timing line was included in those CODEC_ID_SRT
packets is likely because it contained extra information (the event
position) the codec actually needs. This issue is solved by using the
AV_PKT_DATA_SUBTITLE_POSITION side data type.

This commit introduces a new packet side data type for the subtitle
position information. This is meant to be used by the SRT format where
that information is stored along with the timing, which is not part of
the subrip packets.

This allows side data to be transmitted properly with subtitles.

Also fix potential overflow (CID733778)

Allow to factorize buffers initialization/release, for all the writers
which use it. Simplify.

I cannot find a reason for such a rule, which was resulting in badly
escaped filtergraph snippets.

Fix trac ticket #1610.

If someone finds a cleaner fix, dont hesitate to revert this!
