Update the stable DRI port to X.Org 6.7.0-release's DRI modules. Note that
the version number has changed to track the Mesa version instead of the X
release, which is not really related to DRI development. This is because it is
very likely that we will be building the DRI drivers from Mesa soon.
Tested on: XFree86 4.3 + R100, X.Org 6.7.0 + R200
(Only the first 10 of 11 ports in this commit are shown above. )
Add new port "dri". This port contains the split-out DRI client drivers from
XFree86-4-Server. I decided the history from XFree86-4-Server wasn't
significant enough, and will hopefully be obsolete soon when Mesa starts
providing the DRI drivers.
