That way all mix levels as exported by the parser
will have the same meaning.

Previously the 3bit center mix level for eac3 was
used to index in a 4 entry table leading to out of array reads.
this change removes the table and offsets the ac3 variable by 4
so it matches the meanings for eac3 except the reserved case.
The reserved case is then explicitly handled.

Sometimes the scan finds nothing that qualifies for addition to
the array and pos is zero after the loops.  The code forces pos to
1 and the array is then processed as if it had one valid element in it,
producing some amusing but not very useful results.

I don't see the rationale for this.  If pos is zero coming out of the
loops, the only appropriate thing to do is set t->angle to zero.  The
attached patch does that.  It's worked properly in several tests so far.

As the test is run during fate and the benchmark is useless for fate
this very slightly speeds up fate. Its also consistent with the other
tests.

The index for the binary_unit_prefixes array is expected to be positive,
so avoid to use negative indexes for accessing it.

The H.264 decoder needs SPS and PPS for initialization during
multi-threaded decoding. When probed single-threaded SPS and PPS are
copied to extradata and are available for proper initialization of
the decoder before the first frame is decoded.
