Merge remote-tracking branch 'qatar/master'

* qatar/master:
  rtpdec: Use 4 byte startcodes for H.264
  matroskadec: Mark variable as av_unused.
  Move some conditionally used variables into the block where they are used.
  Drop some completely unnecessary av_unused attributes.
  swscale: Remove unused variable alpMmxFilter.
  Drop unnecessary av_uninit attributes from some variable declarations.
  movenc: Support muxing wmapro in ismv/isma
  mpegtsenc: Add an AVOption for forcing a new PAT/PMT/SDT to be written
  swscale: move YUV2PACKED16WRAPPER() macro down to where it is used.
  swscale: handle gray16 as a "planar" YUV format (Y-only, of course).
  swscale: use yuv2packed1() functions for unscaled chroma also.
  swscale: fix incorrect chroma bias in yuv2rgb48_1_c().
  swscale: fix invalid memory accesses in yuvpacked1() functions.
  Move PS2 MMI code below the mips subdirectory, where it belongs.
  mips: Move MMI function declarations to a header.
  build: Set correct dependencies for rtmp* protocols implemented by librtmp.
