  lavf: simplify handling of offset in av_probe_input_buuffer()

Conflicts:
	libavformat/utils.c

The simplification is broken and does not work at least for ffmpeg,
thus this change is not merged.

Always use the actually read size as the offset instead of making
possibly invalid assumptions.

c917cde9cc mpegts muxer, DVB subtitles encoder: common DVB subtitles payload
Improved DVB subtitles encoder to generate AVPacket.data in the same
format as generates MPEGTS demuxer + DVB subtitles parser. So now single
format of DVB subtitles data is used across all the components of FFmpeg:
only subtitles payload WITHOUT 0x20 0x00 bytes at the beginning and 0xFF
trailing byte.

Improved MPEGTS muxer to support format of DVB subtitles in
AVPacket.data described above: while muxing we add two bytes 0x20 0x00 to
the beginning of and 0xFF to the end of DVB subtitles payload.

The patch fixes DVB subtitle copy problems: tickets #2989 fully and #2024
partly.

b00a8b4d19 hevc: remove useless clip in FUNC(sao_band_filter)()
The src buffer should only contain values in the interval
[0, (1 << BIT_DEPTH) - 1]. Since shift = (BIT_DEPTH - 5), src[x] >> shift
must be in the interval [0, 31], so no clip is needed.

This removes the code that was changed in 5856bca360
as the clip that was repositioned in that commit is removed

This is a more proper fix than 5856bca360

previously we did not clip coding units where
cu_transquant_bypass_flag == 1

547f834537 flv: Workaround for buggy Omnia A/XE encoder
The Omnia A/XE encoder writes the explicit extra data incorrectly
and wrongly disables parametric stereo. Truncating the extra data
by setting the size to 2 works around this. The AAC extra data
parser will then only parse the correct parts.
