7d039e70a5 wavpack: extract channel information from the bitstream 
This way we don't require the caller to parse the block header. It also
allows the channel configuration to change mid-stream.

78f75b6fa4 wavpack: extract sample rate from the bitstream 
This way we don't require the caller to parse the block header. It also

9b6f47c448 matroskadec: export full wavpack blocks. 
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.

5074f4545c wavpack demuxer: export full wavpack blocks. 
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.

1d177200ce wavpack: remove a useless check. 
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.

474fb0c9d9 wavpack: return 0 instead of samples count from decoding functions

480b133e6f wavpack: Don't shift minclip/maxclip 
Since we are clipping before we shift the values to
16 or 32 bits, we should not shift the min/max clip
values to compensate.

e6e7bfc11e wavpack: fix clipping for 32-bit lossy mode 
Reference decoder clips data before shifting it to final range and also
forces 32-bit lossy mode to be actually 24-bit lossy mode in order to be
able to perform proper clipping.

aaf47bcde7 Drop ALT_ prefix from BITSTREAM_READER_LE name. 
The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.

2c6cf13940 wavpack: Reset internal state on corrupted blocks

same buffer unless it has returned with an error. With multi-channels
files, wavpack_decode_frame() was breaking this assumption.

9bc4e21a9b wavpack: use context reset in appropriate places 
This fixes improper flushing in the cases when the same frame is decoded in
several iterations (for being too large to fit into output buffer) and flush is
called mid-decoding and it also resets context in case of decoding errors.
