Merge remote-tracking branch 'qatar/master'

* qatar/master:
  avformat: Drop pointless "format" from container long names
  swscale: bury one more piece of inline asm under HAVE_INLINE_ASM.
  wv: K&R formatting cosmetics
  configure: Add missing descriptions to help output
  h264_ps: declare array of colorspace strings on its own line.
  fate: amix: specify f32 sample format for comparison
  tiny_psnr: support 32-bit float samples
  eamad/eatgq/eatqi: call special EA IDCT directly
  eamad: remove use of MpegEncContext
  mpegvideo: remove unnecessary inclusions of faandct.h
  af_asyncts: avoid overflow in out_size with large delta values
  af_asyncts: add first_pts option
