[MEMO]
In this commit, no version changed. But if you put
'WITHOUT_NOUVEAU' on /etc/make.conf, you can use
new version of Mesa3D and libdrm.
Discussed with: rnoland on freebsd-ports/freebsd-x11.
- Bump PORTREVISION for all ports depending on libglut since the shlib
version number went from 4 to 3.
- Bump PORTREVISION for all ports depending on libXaw as libXaw.so.8 isn't
installed anymore.
- Couple of ports fixes (mostly missing xorg components added to USE_XORG).
