The most interesting parts are initialization in ff_MPV_common_init() and
uninitialization in ff_MPV_common_end().
ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL
checks for Picture.f, because these functions can be called on
uninitialized or partially initialized Pictures.
NULL pointer checks are added to ff_thread_release_buffer() stub function.

Its usefull to know immediatly if extradata is wrong and not just when later
the decoder tries to use it.

It has been checking the number of bits in the offset instead of the
actual offset.

The mask `x && (1 << y)' is incorrect and always yields true.
The correct form should be `x & (1 << y)'.

This prevents undefined behaviour of signed left shift if the coded
value is larger than 2^31. Large values are most likely invalid and
caused errors or by feeding random.
Validate every use of svq3_get_ue_golomb() and changed the place there
the return value was compared with negative numbers. dirac.c was clean,
fixed rv30 and svq3.
This makes no differnce as the affected values cannot occur
But it will likely help static analyzers
