9851184d30 Reset internal state on corrupted blocks in wavpack decoder. 
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.

7aa24b157d h264: ff_h264_decode_extradata: check buffer args 
The buffer size and pointer were not checked prior to testing the first
byte of the buffer. These were sometimes checked before calling, but it is
better to add it inside the function as it takes buf and size arguments.
