Merge remote-tracking branch 'newdev/master'

* newdev/master: (33 commits)
  Fix an infinite loop when RoQ encoded generated a frame with a size greater than the maximum valid size.
  Add kbdwin.o to AC3 decoder
  Detect byte-swapped AC-3 and support decoding it directly.
  cosmetics: indentation
  Always copy input data for AC3 decoder.
  ac3enc: make sym_quant() branch-free
  cosmetics: indentation
  Add a CPU flag for the Atom processor.
  id3v2: skip broken tags with invalid size
  id3v2: don't explicitly skip padding
  Make sure kbhit() is in conio.h
  fate: update wmv8-drm reference
  vc1: make P-frame deblock filter bit-exact.
  configure: Add the -D parameter to the dlltool command
  amr: Set the AVFMT_GENERIC_INDEX flag
  amr: Set the pkt->pos field properly to the start of the packet
  amr: Set the codec->bit_rate field based on the last packet
  rtsp: Specify unicast for TCP interleaved streams, too
  Set the correct target for mingw64 dlltool
  applehttp: Change the variable for stream position in seconds into int64_t
  ...
