Also add missing trailing commas, break long codec_tag lines and
add spaces in codec_tag declarations.

Make the muxers/demuxers that use the field handle the default
-1 in the same way as 0.
This allows distinguishing an intentionally set 0 from the default
value where the user hasn't set it.

When segmenting the output from the mpegts muxer, one can
now set this option when cutting to a new segment, to make sure
the next segment starts with PAT/PMT/SDT.

-vbsf doesn't exist anymore. It got renamed to -bsf somewhere along the
line. Update print statement accordingly.

With the current default PES packet size, and very small audio bitrates,
audio packet duration gets too long. For players, which wait for a whole
audio packet (or more) it takes a very long time to start playing sound.
For 24kbps audio, one PES packet is about 1 second long. On Motorola STBs,
we observe about 3 second delay before the playback starts with the
default setting.

Since a private class is set for this muxer, the callers will
assume that the private data starts with an AVClass pointer.
If no such member exists, the first few bytes of the struct
will be overwritten, and the class pointer may be broken at
any later time.

The mpegts muxer does not set the stream time base using
av_set_pts_info, but expects it to have the default value of 1/90000.
If the calling code changes stream pts before writing the header,
other muxers override the time base at that point (like mpegenc.c).
This adds the AAC codec to the list of audio codecs that results
in a PES stream_id of 0xc0 (audio stream).

In the name of consistency:
put_byte -> avio_w8
put_<type> -> avio_w<type>
put_buffer -> avio_write
put_nbyte will be made private
put_tag will be merged with avio_put_str

See attached. I hope the documentation is enough.

According to EN 300 468 section 3.1 (Definitions):
Unless otherwise specified within the present document all
"reserved_future_use" bits is set to "1".
This was not the case for SDT generation so this patch fixes it.

This patch adds support in mpegts muxer for using service_provider and
service_name metadata to set service_provider_name and service_name
fields in SDT.
Example usage:
ffmpeg -i file.ts -f mpegts -re -acodec copy -vcodec copy -f mpegts \
-metadata service_provider="Some provider" \
-metadata service_name="Some Channel" \
"udp://239.0.70.2:5000?pkt_size=1316&ttl=1"

This fixes PCR drift due to accumulating TS_PACKET_SIZE*8*90000LL/ts->mux_rate each packet, due to rounding errors when mux_rate does not evenly divide 135360000.
This patch also increases the PCR precision to 27 MHz from 90 kHz and takes the location of the PCR data into account (+11 bytes according to the spec).
