math/blas, math/lapack: Install interchangeable BLAS system

Install the new interchangeable BLAS system created by Thomas Orgis,
currently supporting Netlib BLAS/LAPACK, OpenBLAS, cblas, lapacke, and
Apple's Accelerate.framework.  This system allows the user to select any
BLAS implementation without modifying packages or using package options, by
setting PKGSRC_BLAS_TYPES in mk.conf. See mk/blas.buildlink3.mk for details.

This commit should not alter behavior of existing packages as the system
defaults to Netlib BLAS/LAPACK, which until now has been the only supported
implementation.

Details:

Add new mk/blas.buildlink3.mk for inclusion in dependent packages
Install compatible Netlib math/blas and math/lapack packages
Update math/blas and math/lapack MAINTAINER approved by adam@
OpenBLAS, cblas, and lapacke will follow in separate commits
Update direct dependents to use mk/blas.buildlink3.mk
Perform recursive revbump

Switch packages using GLUT to FreeGLUT.

Start building FreeGLUT with GLUT compatibility on.

- GLUT's maintainance state is much worse than FreeGLUT's, with no
  substanital commits since 2011.
- GLUT can no longer be consider a core component of Mesa or X11.
- Nobody except us seems to be using it...

Other vendors still shipping GLUT:
- GoboLinux, T2 SDE, PLD Linux

Revbump packages using GLUT or freeglut by default.
