mpegvideoparse: Handle Sequence Display Extension
...
Change the way the pixel-aspect-ratio is computed by
interpreting the sequence header aspect ratio info
as MPEG-1 values until a sequence extension or
sequence display extension is seen, and then updating
the sequence header struct accordingly.
Fixes incorrect anamorphic display on some MPEG-2 (DVD)
sequences.

Fix 'ignoring return value of function declared with const attribute'
...
This always happens with GstByteReader/Writer and friends when
not taking into account returned boolean of the _read/_write functions
(which is actually wrong).
Make use of the *_unchecked variant as much as possible, or take the
returned value into account.
