29b1af40f3 avformat/mpegts: add scan_all_pmts option 
This allows selecting if the demuxer should consider all streams to be
found after the first PMT and add further streams during decoding or if it rather
should scan all that are within the analyze-duration and other limits

db0471c40f avformat/mpegts: Continue parsing PMTs during duration estimation 
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

5adcef9c1b mpegts: pass MpegTSContext ptr explicitly 
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.

8635954335 avformat/mpegts: pass MpegTSContext ptr explicitly (fixes #3721) 
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.

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