* qatar/master:
  swscale: Fix stack alignment for SSE
  avcodec: move some AVCodecContext fields to an internal struct.
  avcodec: use av_opt_set() instead of deprecated av_set_string3()
  avcodec: fix some const warnings
  avcodec: remove pointless AVOption, internal_buffer_count
  imgutils: Fix illegal read.

2011-10-20 - b35e9e1 - lavu 51.22.0
Add av_strtok() to avstring.h.
2011-xx-xx - xxxxxxx - lavc 53.21.0
Move some AVCodecContext fields to a new private struct, AVCodecInternal,
which is accessed from a new field, AVCodecContext.internal.
- fields moved:
AVCodecContext.internal_buffer --> AVCodecInternal.buffer
AVCodecContext.internal_buffer_count --> AVCodecInternal.buffer_count
AVCodecContext.is_copy --> AVCodecInternal.is_copy
2011-11-13 - lavf 53.15.0
New interrupt callback API, allowing per-AVFormatContext/AVIOContext
interrupt callbacks.
