  build: Drop YASM-OBJS-FFT from SUBDIR_VARS.
  build: Drop unused X86-OBJS variable.
  avconv: remove debugging cruft from do_video_out().
  avconv: factorize setting stream_index for the output packet.
  frame{crc/md5}: set the stream timebase from codec timebase.
  apedec: remove unneeded #include of get_bits.h and associated macro
  apedec: av_fast_malloc() instead of av_realloc()
  apedec: fix handling of packet sizes that are not a multiple of 4 bytes
