    avcodec/x86/lossless_videoencdsp_init: Don't read from before the buffer
sub_median_pred_mmxext() calculates a predictor from the left, top
and topleft pixel values. The left value is simply read via
ptr[-1], although this is not guaranteed to be inside the buffer
in case of negative strides. This happens e.g. with

ffmpeg -i fate-suite/mpeg2/dvd_single_frame.vob -vf vflip \
       -c:v magicyuv -pred median -f null -

Fix this by reading the first value like the topleft value.
Also change the documentation of sub_median_pred to reflect this
change (and the one from 791b5954bc8fe7c0077d7eb959ebd17e40d0a7c6).

    avcodec/x86/lossless_videoencdsp_init: Don't read too often
sub_median_pred_mmxext() calculates a predictor from the left, top
and topleft pixel values. The topleft values need to be initialized
differently for the first loop initialization than for the others
in order to avoid reading ptr[-1]. So it has been initialized before
the loop and then read again at the end of the loop, so that the last
value read was never used. Yet this can lead to reads beyond the end
of the buffer, e.g. with
ffmpeg -cpuflags mmx+mmxext -f lavfi -i "color=size=64x4,format=yuv420p" \
-vf vflip -c:v ffvhuff -pred median -frames 1 -f null -

Fix this by not reading the value at the end of the loop.
