* rbultje/vp9-simd:
  vp9: implement top/left half (4x4) sub-8x8-IDCT.
  vp9: split pre-load of 11585x2 out of 1d idct macro.
  vp9: minor refactorings in idct ssse3 assembly.
  vp9: split x86 assembly in two files.
Merged-by: Michael Niedermayer <michaelni@gmx.at>

For that specific case (eob>3&&eob<=12), runtime of idct8x8 goes from
668 to 477 cycles. For all idct8x8, runtime goes from 521 to 490 cycles.

This allows us to load it only once, instead of twice, in this function.

Make register usage in macros explicit; change mulsub_2w_4x to use 2
instead of 3 temp registers.

(And in future, loopfilter or intra pred could be put in their own
respective files also.)

* cus/stable:
  ffplay: set default window size before starting audio
  ffplay: factor out function setting default window size
  ffplay: remove no longer necessary codec flush
  ffplay: do not wait for flushing the picture queue on flush packet

It was introduced in c2e8691c, but since we no

It is no longer necessary. Also do frame timer and video current pos reset in
the main thread because with the wait removed, the timing would not be optimal
in the read thread.
