Merge remote-tracking branch 'qatar/master' 

* qatar/master:
  swscale: make yuv2yuv1 use named registers.
  h264: mark h264_idct_add8_10 with number of XMM registers.
  swscale: fix V plane memory location in bilinear/unscaled RGB/YUYV case.
  vp8: always update next_framep[] before returning from decode_frame().
  avconv: estimate next_dts from framerate if it is set.
  avconv: better next_dts usage.
  avconv: rename InputStream.pts to last_dts.
  avconv: reduce overloading for InputStream.pts.
  avconv: rename InputStream.next_pts to next_dts.
  avconv: rework -t handling for encoding.
  avconv: set encoder timebase for subtitles.
  pva-demux test: add -vn
  swscale: K&R formatting cosmetics for SPARC code
  apedec: allow the user to set the maximum number of output samples per call
  apedec: do not unnecessarily zero output samples for mono frames
  apedec: allocate a single flat buffer for decoded samples
  apedec: use sizeof(field) instead of sizeof(type)
  swscale: split C output functions into separate file.
  swscale: Split C input functions into separate file.
  bytestream: Add bytestream2 writing API.

The avconv changes are due to massive regressions and bugs not merged yet.
