Fixed the logic for seeking in ffmpeg video files. The main fix is that we now apply a small offset in ffmpeg_get_seek_pos to make sure we don't get the frame in front of the seek position when seeking backward. The rest of the changes is general cleanup and untangling code. Reviewed By: Richard Antalik Differential Revision: http://developer.blender.org/D11492
