Mesa3D BEP

[kallisti5]

This is my in-development Mesa3D BEP.

This bep is not complete, and will be a lot more stable once Mesa 9.0 comes out.

This port is a little 'strange' as it's sole purpose is to generate a zip which is used by the Haiku build system.

mesa-9.0.diff is *not* ready for prime time as the OpenGL kit needs adjusted to use it.

Problems:

• libglu was removed from Mesa 9.0, so we need to add libglu to the build system (our glut uses libglu)
• radeon (and other) gallium drivers don't build for Haiku... seems like a cherry pick was missed for 9.0 :(
• A few small OpenGL git changes

This bep does however generate a package for gcc4 Haiku builds and place it in your home directory with the correct naming to be an optional package.

committed in 2098.

This is used to generate an optional package for the OpenGL kit. This should *not* be installed via -i or made into an optional package via -d! (we wrap up private headers for the OpenGL kit via a script)
