This is needed for SAMI and RealText demuxers.

The "Default" style written in the header is ignored unless you explicit
it in the Dialogue events (it was valid, just ignored). This requires an
update of the SubRip test since the ASS output obviously changes.

Consistent with the rest of the file, less confusing.

This simplifies usage for segment streaming formats with no global
headers, tipically MPEG 2 transport stream "ts" files.

The seg class duplication is required in order to avoid an infinite loop
in libavformat/utils.c:format_child_next_class().

Consistent with av_find_input_format().

Patch is addition to my previous patch
(https://lists.ffmpeg.org/pipermail/ffmpeg-cvslog/2012-June/051590.html)
and disables seeking on FIFOs/named pipes by setting
URLContext::is_streamed (same as pipe: protocol does for stdin/stdout pipes)

swr_free() already checks for nullness, no need to add the check in
calling code.

The comment now references swr_convert(), rather than audio_convert(),
which was deprecated and/or dropped.

Favor av_buffersrc_add_ref() instead, which is more powerful.

Below fixes the maximum reference count check for second reference list in
non-B frames.  There is nothing to prohibit full (field sized) reference
list in this case as far as I can tell, and this fixes several syntax-test
files here (this is a regression caused when this check was made more
stringent by
http://git.videolan.org/?p=ffmpeg.git;a=commit;h=dc9ce40069bde3d28f8d0b3e5bd733ae255fecb5)

Probably a silly corner case seldom seen irl, but thought I'd pass along
in case there was interest in correcting the check.
