Merge remote-tracking branch 'qatar/master'

* qatar/master: (29 commits)
  ARM: disable ff_vector_fmul_vfp on VFPv3 systems
  ARM: check for VFPv3
  swscale: Remove unused variables in x86 code.
  doc: Drop DJGPP section, Libav now compiles out-of-the-box on FreeDOS.
  x86: Add appropriate ifdefs around certain AVX functions.
  cmdutils: use sws_freeContext() instead of av_freep().
  swscale: delay allocation of formatConvBuffer().
  swscale: fix build with --disable-swscale-alpha.
  movenc: Deprecate the global RTP hinting flag, use a private AVOption instead
  movenc: Add an AVClass for setting muxer specific options
  swscale: fix non-bitexact yuv2yuv[X2]() MMX/MMX2 functions.
  configure: report yasm/nasm presence properly
  tcp: make connect() timeout properly
  rawdec: factor video demuxer definitions into a macro.
  rtspdec: add initial_pause private option.
  lavf: deprecate AVFormatParameters.width/height.
  tty: add video_size private option.
  rawdec: add video_size private option.
  x11grab: add video_size private option.
  x11grab: factorize returning error codes.
