Three component formats are not very helpful, at least the Intel driver doesn't
expose them as color renderable, and other drivers most likely also just emulate
them using RGBX textur formats. RGB32* we have to keep though because it is needed
for ARB_rbo_rgb32 which in turn is needed for OpenGL 4.0.
To handle the latter, mesa/virgl will take care that RGB32* textures are only
allocated as buffers objects.

There's a few minor mistakes in the old license statement, for
instance:
- missing the year 2014 from the copyright
- "without limitation the" instead of "without limitation on the"
Apart from that it's just minor details like wrapping, and adding
"(including the next paragraph)". None of this seems to change
anything from a legal standpoint.
This matches the copyright-header we have for the same file in
Mesa, and makes it a bit less noisy to update the file there.
