  tests: Refactor rotozoom/videogen common code into a separate file.
  tests: Mark some file-internal symbols as static.
  build: Drop leftover .exp pattern from LIBSUFFIXES list.
  vsrc_buffer: return EAGAIN if no frame is available.
  WMAL: Shift output samples by the specified number of padding zeroes.
  WMAL: Restore removed code in mclms_predict()
  rtpdec_h264: Remove a useless ifdef
  rtpdec_h264: Remove outdated/useless/incorrect comments
  rtpdec_h264: Remove useless memory corruption checks
  rtpdec_h264: Return proper error codes
  rtpdec_h264: Check the available data length before reading
  rtpdec_h264: Add input size checks
  png: check bit depth for PAL8/Y400A pixel formats.
  ea: check chunk_size for validity.
  celp filters: Do not read earlier than the start of the 'out' vector.
