Merge remote-tracking branch 'qatar/master' 

* qatar/master:
  rv30: return AVERROR(EINVAL) instead of EINVAL
  build: add -L flags before existing LDFLAGS
  simple_idct: whitespace cosmetics
  simple_idct: make repeated code a macro
  dsputil: remove huge #if 0 block
  simple_idct: change 10-bit add/put stride from pixels to bytes
  dsputil: allow 9/10-bit functions for non-h264 codecs
  dnxhd: rename some data tables
  dnxhdenc: remove inline from function only called through pointer
  dnxhdenc: whitespace cosmetics
  swscale: mark YUV422P10(LE,BE) as supported for output
  configure: add -xc99 to LDFLAGS for Sun CC
  Remove unused and non-compiling vestigial g729 decoder
  Remove unused code under G729_BITEXACT #ifdef.
  mpegvideo: fix invalid picture unreferencing.
  dsputil: Remove extra blank line at end.
  dsputil: Replace a LONG_MAX check with HAVE_FAST_64BIT.
  simple_idct: add 10-bit version
