rar5 SSE:  Work started. This code change now uses pbkdf2_hmac_sha256.h
It does NOT yet do SSE2, but is starting to set things up.  NOTE, we will have to do
the last 32 hmacs outside of SSE2 (probably)
Got RAR5 working with SSE2.  NOTE, OMP is broken.  I have looked, but see nothing wrong
rar5_fmt:  Found my OMP bug (stupid me)
Fix a formatting problem in sha256 OpenCL kernel file.
On --list=opencl-devices show PCI information for NVIDIA cards.
