90f8cca04e video: add VUYA pixel format 
AYUV in gstreamer was defined in A-Y-U-V order in memory[1], however
Microsoft defined another AYUV format in V-U-Y-A order in memory[2]. Add
VUYA format for the latter in order to distinguish the two formats

103d265cf0 Fix RGBA and ABGR pack/unpack on big endian cpu 
The pack and unpack functions for RGBA and ABGR only work for little
endian cpus. Add variants for big endian as well.

7a40442ad5 video: Add VYUY pixel format 
This format is sometimes the output of JPEG decoders. It is the same as
YUY2 and UYVY but with a different component order.

8239da2311 video-dither: Use saturated add when adding ordered dither for > 8 bit targets 
Otherwise our 16 bit integers are going to overflow in intermediate
calculations, causing video to become mostly black.

b2fd20c416 video: move videoconvert code to video library

and expose a simple but generic API to do arbitrary conversion. It can
currently do colorspace conversion but the plan is to add videoscale to
it as well.
