because of bad alignment.

60d18149e5 video-format: sprinkle some 'restrict' keywords in pack/unpack functions 
In cases where we just call orc directly this is somewhat
superfluous, but let's do it anyway for consistency. In
other cases the compiler can hopefully use this to optimise
memory access a little.

a3da634db6 video-format: improve unpack i420 
unpack_i420 does not need extra code to handle odd widths, the orc code
already handles it fine.

cecb900704 video-format: fix pack of 4:2:0 formats 
When packing 4:2:0 formats, we need to take the chroma from the even
lines, for the odd lines we only take luminance.

f52fd7a68b video: Don't use extra plane and componenent for tile format 
Instead of using extra plane, we encode the number of tiles in x and y in the stride of
each planes (i.e. y_tiles << 16 | x_tiles) and introduce tile_mode, tile_width and
tile_height into GstVideoFormatInfo structure.

c1a25d2ce7 video-format: fix interlaced 4:2:0 and 4:1:0 pack/unpack 
For interlaced vertically subsampled images we need to combine alternating
chroma lines with alternating luma lines. That is line 0 and 2 are combined
with the first line of chroma samples and line 1 and 3 with the second line
of chroma samples.
