a4899af8d6 mpegtspacketizer: Offset calculation 
Allows PCR<=>PTS<=>offset estimation/calculation
Right now the calculation is very naive, but can be extended later on
without disrupting the code in tsdemux/mpegtsbase

39cc29a7d2 mpegtspacketizer: clock fix and minor addition 
* Don't take into account packets that arrived at the same time as
  previous ones for clock skew estimation
* Add convenience method for processing the next ts packet

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.

818762e8fc tsdemux: do not send a new-segment on stream removal 
When a program is changed, stream_added is called which sets the
need_newsegment to TRUE, then stream_removed is called, which calls
the flush_pending_data, which checks for the newsegment and causes
it to send a new-segment.

We must not send the newsegment when flushing the pending data on the
removed stream. We should only push it when flushing data on the newly
added streams (after they finish parsing their PTS header)

382710e200 tsdemux: Fix newsegment when switching programs 
If a program/stream is changed, then a newsegment is sent which must

and the current PTS of the stream

57279cdd24 tsdemux: Refactor stream/program removal 
The program_stopped vmethod was called before stream_removed vmethod
was being called. Since we only did stream-related operations in there,
we just remove the program_stopped vmethod and do everything in the
stream_removed one.

Also, make sure we flush out all pending data before sending EOS.

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).

d0e8427b4e pesparse: Fix stuffing byte handling
