f604eab30a wavpack: Fix an integer overflow
Integer Overflow Checker detected an integer
overflow while FATE was running.

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.

Fixes 8 and 24 bit lossy decoding.

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
wavpack_decode_block() supposes that it is called back with the exact
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.

737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.
