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

d0e8427b4e pesparse: Fix stuffing byte handling
We in fact get the size of the header (including stuffing bytes), therefore
use that instead of trying to skip 0xff bytes ourselves since some media
streams do start with 0xff (like mpeg audio's initial 0xfff).

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.

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
