lavc: add avcodec_is_open().
It allows to check whether an AVCodecContext is open in a documented way. Right now the undocumented way this check is done in lavf/lavc is by checking whether AVCodecContext.codec is NULL. However it's desirable to be able to set AVCodecContext.codec before avcodec_open2().
