* qatar/master: (28 commits)
  Remove some non-compiling debug messages.
  ffplay: Fix non-compiling debug printf and replace it by av_dlog.
  H264: x86 predict init cosmetics.
  ac3enc: Fix linking of AC-3 encoder without the E-AC-3 encoder.
  Move E-AC-3 encoder functions to a separate eac3enc.c file.
  ac3enc: remove convenience macro, #define DEBUG
  ac3enc: remove unused #define
  vc1: re-initialize tables after width/height change.
  APIchanges: fill-in git commit hash for av_get_bytes_per_sample() addition
  samplefmt: add av_get_bytes_per_sample()
  iirfilter: fix biquad filter coefficients.
  swscale: remove duplicate conversion routine in swScale().
  swscale: add yuv2planar/packed function typedefs.
  swscale: integrate yuv2nv12X_C into yuv2yuvX() function pointers.
  swscale: reindent x86 init code.
  swscale: extract SWS_FULL_CHR_H_INT conditional into init code.
  swscale: cosmetics.
  swscale: remove alp/chr/lumSrcOffset.
  swscale: un-special-case yuv2yuvX16_c().
  shorten: Remove stray DEBUG #define and corresponding av_dlog statement.
