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)

Fixes Ticket986

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.
