  vp8: fix return value if update_dimensions fails
  matroskadec: fix out of bounds write
  adpcmdec: calculate actual number of output samples for each decoder.
  adpcmdec: check remaining buffer size before decoding next block in the ADPCM IMA WAV decoder.
  adpcmdec: do not terminate early in ADPCM IMA Duck DK3 decoder.
  adpcmdec: remove unneeded buf_size==0 check.
  adpcmdec: remove unneeded zeroing of *data_size
