Michael Niedermayer 6a287b739f Detect and prevent reading over the end of counts_*. We pass the error
through a context variable as this is simpler and i think also faster, but
the return value of functions could be used instead of course.
The code also ensures as a side effect that the AC decoder state does not
become invalid.
This fixes all known crashes. And outputs nothing in case of an error instead
of random noise.
