The quantization code needs more work, not so much work
merging but more work investigating what is correct.

This allows us to get rid of demuxer-specific hacks in the decoder and
will allow streamcopy from matroska once we have a wavpack muxer.

Currently the demuxer shaves the blocks and exports only the
information that is useful to the decoder.

Exporting the blocks just as they are stored is simpler to understand
and will make remuxing wavpack easier.

We don't know whether it will be float until we look at the data.

Conflicts:

Merged-by: Michael Niedermayer <michaelni@gmx.at>

The decoder always returns output if an error does not occur.

Such blocks are not valid.

Number of samples in the first block is checked to be strictly positive
earlier in wavpack_decode_frame() and number of samples in all the other
blocks is checked to be equal to the first one.

The caller never cares about the number of decoded samples, so this only
confuses the reader.

This simplifies the code and makes it faster.

The decoder always consumes full packets.
