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

golomb: use unsigned arithmetics in svq3_get_ue_golomb()
...
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.
