c557f71756 tsdemux: Push packets as early as possible
When the PES header tells us how big the outgoing packet is, push the
packet downstream as soon as we have the specified size instead of waiting
for the beginning of the next packet.
Reduces latency and removes issues with very sparse streams (like subtitles
and subpictures).

01f5f62d95 tsdemux: Fix segment start position
If we *really* can't figure out the first start position, that most
likely means the data to push out doesn't have any timestamp.
Use a default value of 0 then

c10fc17a1e Revert "mpegtsdemux: Not apply various time the same PMT to a program when repetead"
This reverts commit 8cb0e87f56.

mpegtspacketizer already checks if it's a new PMT or not

5c2e6dc512 mpegtspacketizer: catch section lengths extending past the buffer length
This is probably the cause for an occasional crash while streaming
MPEG. Blind fix after staring at the code and following logic, so
may or may not fix the issue, I cannot test.

8cb0e87f56 mpegtsdemux: Not apply various time the same PMT to a program when repetead
Sometimes their are several times the same PMT applying to a same program in a stream,
tsdemux was totally baffled when this was happening, we now keep the one we
already applied so it works properly.
