Merge remote-tracking branch 'newdev/master'

* newdev/master:
  avio: make udp_set_remote_url/get_local_port internal.
  asfdec: also subtract preroll when reading simple index object
  matroskaenc: remove a variable that's unused after bc17bd9.
  avio: cosmetics - nicer vertical alignment.
  Remove unnecessary icc version checks
  Disable 'attribute "foo" ignored' warnings from icc
  rtsp: Don't use a locale dependent format string
  Add xd55 codec tag for XDCAM HD422 720p25 CBR files.
  configure: get libavcodec version from new version.h header
  lavc: move the version macros to a new installed header.
  matroskaenc: simplify get_aac_sample_rates by using ff_mpeg4audio_get_config
  Do not use format string "%0.3f" for RTSP Range field.
  Add apply_window_int16() to DSPContext with x86-optimized versions and use it in the ac3_fixed encoder.
  Document usage of import libraries created by dlltool
  configure: Set the correct lib target for arm/wince dlltool
  fate: simplify regression-funcs.sh
  fate: add support for multithread testing
