[Ipopt] Intel has made their MKL freely available for Win, Lin and OSX

[Damien]

Actually, it's not ten years out of date.  It's ten years' diverged from 
the original code, but if you look at the changelog for the releases 
Intel has put a significant amount of work into Pardiso to improve 
performance and robustness.  We use MKL Pardiso in optimal control 
problems with over 20 million variables and it's by far the fastest 
linear solver at that scale in IPOPT, especially on Intel hardware.
