  aes: Avoid illegal read and don't generate more key than we use.
  mpc7: Fix memset call in mpc7_decode_frame function
  atrac1: use correct context for av_log()
  apedec: consume the whole packet when copying to the decoder buffer.
  apedec: do not needlessly copy s->samples to nblocks.
  apedec: check output buffer size after calculating actual output size
  apedec: remove unneeded entropy decoder normalization.
  truespeech: use memmove() in truespeech_update_filters()
  vorbisdec: remove AVCODEC_MAX_AUDIO_FRAME_SIZE check
  vorbisdec: remove unneeded buf_size==0 check
  vorbisdec: return proper error codes instead of made-up ones
  http: Don't add a Range: bytes=0- header for POST
  sunrast: Check for invalid/corrupted bitstream
  http: Change the chunksize AVOption into chunked_post
  http: Add encoding/decoding flags to the AVOptions
  avconv: remove some codec-specific hacks
  crypto: add decoding flag to options.
  tls: use AVIO_FLAG_NONBLOCK instead of deprecated URL_FLAG_NONBLOCK
