[OpenAFS] OpenAFS and windows/unix versioning

[Harald Barth]

"In sync" would have been nice, but as "in sync" has been problematic
in the past and I don't expect that to change, I suggest to go with
the last suggestion. I would call it "marketing numbers" and these
should have another range so that they have clearly differing version
numberings (like the 5.x example from Andrew). Or call the Windows
versions 14.x this year and 15.x next year. Then we will never reach
the feared OfW-13 version for sure ;-)

Harald.
