This way if we by chance run into a valid PMT we have a more complete
set of streams, also do not reset streams in case we run into a worse
PMT
Fixes Ticket4046
alternatively Ticket4046 could be closed as invalid or wontfix as it contains
some PMTs which lack the 2 subtitle streams

AVFormatContext->priv_data is not always a MpegTSContext, it can be
RTSPState when decoding a RTP stream. So it is necessary to pass
MpegTSContext pointer explicitly.
Within libav, the write_section_data function doesn't actually use
the MpegTSContext at all, so this doesn't change anything at the
moment (no memory was corrupted before), but it reduces the risk of
anybody trying to touch the MpegTSContext via AVFormatContext->priv_data
in the future.

MpegTSContext pointer explicitly.
This fixes memory corruption from bug #3721 (RTSPState is smaller than
MpegTSContext thus innocent memory gets overwritten).

We cannot easily determine if an mpeg TS's packet size is DVHS, FEC
or so on, for that we need to expose the internal raw_packet_size
field.

This (ugly) hack fixes Ticket3348
If someone has an idea on how to fix this nicer, that would be very welcome
but the stream contains several PMTs with just one of the 2 streams at the start

Used in some HLS streams ("Timed Metadata for HTTP Live Streaming").
This is just ID3 tags at arbitrary stream positions, but I still added
"timed" to the codec name to avoid confusion with regular non-stream ID3
tags.
