Hans Petter Selasky d6b92ffa99 OFED user-space import and update for use with Linux-4.9 compatible RDMA 
kernel APIs.

List of sources used:

1) rdma-core was cloned from "https://github.com/linux-rdma/rdma-core.git"
Top commit d65138ef93af30b3ea249f3a84aa6a24ba7f8a75

2) OpenSM was cloned from git://git.openfabrics.org/~halr/opensm.git
Top commit 85f841cf209f791c89a075048a907020e924528d

3) libibmad was cloned from "git://git.openfabrics.org/~iraweiny/libibmad.git"
Tag 1.3.13 with some additional patches from Mellanox.

4) infiniband-diags was cloned from "git://git.openfabrics.org/~iraweiny/infiniband-diags.git"
Tag 1.6.7 with some additional patches from Mellanox.

Added the required Makefiles for building and installing.
