cbc0a2f056 mpegtsbase: Prevent stack gardening by using the right type
stream_type is stored as guint inside the GstStructure but was retreived
using valist with a pointer to guint16. This would cause stack gardening
when code is compiled without optimisation (e.g. in -O0 the compiler wont
pad the stack to optimise out required mask).

634d29cd88 mpegtsbase/tsdemux: Fix stream/pad activation order
We first activate new streams before shutting down old ones.
We emit no-more-pads after we add new streams and emit EOS before
removing old ones.
Also cleanup/refactor a bit more of the code accordingly

2b127601e9 mpegtsbase: Avoid double removal of streams
This can happen if the PCR pid is the same as a audio/video PID.

b170b2020c mpegtsbase: Add a GList of streams to the program
Allows faster iteration of all program streams.

We still keep the Array to allow fast retrieval of stream by PID.

a82483e367 mpegtsbase: Split up whether we saw a PAT and its offset
Fixes the issue with streams that don't set an offset on their buffers,
like those coming from hlsdemux.

Fixes #653481

3ce1ec7c9c mpegtsdemux: accurate seeking
* pes header parsing for pts is ugly, refactor
 * timestamps/newsegment after seeking is still off

15391b29e1 mpegtsdemux: push based seeking based on PCR
buffer timestamps are converted to GstClockTime to cover pcr/pts wraps.
multiple pcr/pts wraps are handled with an index which ensures at most
a single pcr wraparound between two entries.
the last seen pcr is recorded to have a nearby index point for short seeks
resuming playback might be delayed if the postion is not a keyframe

TODO: replace manual packet scanning and parsing in the initial duration estimation

74a8e966f5 mpegtsdemux: fix playback if PMT is seen before PAT
The stream for the PMT pid has to be cleared since the version checking
in the packetizer won't emit the same PMT again otherwise.
