[Ilia Valiakhmetov]

Tile threading is ~45% faster at 2 threads vs 1.
Frame threading is ~55% faster at 2 threads vs 1.
ffvp9 tile threading is ~25% faster than libvpx-vp9 at 2 threads

execute3() function is similar to execute2(), execept it has
a extra argument - main function for avpriv_slicethread_create(), it is used for the loopfilter.

Ilia Valiakhmetov (2):
  avcodec: add execute3() api to utilize the main function of
    avpriv_slicethread_create().
