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.

5c043f3d50 video-format: handle unpack interlaced subsampled formats 
For interlaced vertically subsampled formats the check for even lines
needs to take into account the two fields.

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.

a18c098f82 video: add option to unpack and truncate the range 
Add an unpack option to specify what to do with the least significant bits of
the destination when the source format has less bits than the destination. By
default we will now copy the most significant bits of the source into the least
significant bits of the destination so that the full color range is represented.
Add an option to leave the extra destination bits 0, which may be faster and
could be compensated for in the element algorithm.
