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.

DECLARE_ALIGNED_8 is not defined at that point, but this code is powerpc
only, so it's really equivalent to DECLARE_ALIGNED(16...

d8870f120e use scale factor instead of sum for downmix level adjustment. avoids division
inside downmix loop. 7% faster 5.1-to-stereo downmixing.
