Ronald S. Bultje b64a72e1b2 yuv2rgb: handle line widths that are not a multiple of 4.
This introduces support for width%4==2 in addition to width%4==0. For
odd widths, some more checks are needed, since the current code always
handles two luma items in a row, thus there is a possibility of an
overread by one.

Benoit Fouet 453d28af60 Change the type of Y table to pointer to void in fill_table().
This fixes warnings about wrong type being used, e.g.:
libswscale/yuv2rgb.c: In function ‘ff_yuv2rgb_c_init_tables’:
libswscale/yuv2rgb.c:778: warning: passing argument 4 of ‘fill_table’ from incompatible pointer type
libswscale/yuv2rgb.c:598: note: expected ‘uint8_t *’ but argument is of type ‘uint16_t *’
