This reverts commit c813adf6.

Reason for revert: Needed to revert other CLs that caused a
regression in video_VideoSeek: https://crbug.com/834146
Bug: 834146

Original change's description:
> vaapi: cleanup a few comments and var names
>
> This CL cleans up a few things that I realized while
> debugging other CLs in the area:
> - |available_va_surfaces_| is a std::list on ToT, but has
>  queue semantics, so it's changed int his CL.
> -  s/output_buffers_/available_va_surfaces_/ because that's
>  what they are.
> - s/TryOutputSurface/TryOutputPicture/ because that's what
>  the method does.
> - s/pictures_/picture_map_/ to better define what it is. After
>  dcastagna@ suggestion, it's made a base::small_map in PS7
>
> Comments updated throughout these variables.
>
> No change in behaviour intended, but tested nonetheless with
> vp8/9-h264 crosvideo playback.
>
