Subject: OpenCL version of krb5 aes256-cts-hmac-sha1-96 as-req pre-auth committed

We now have a first take of krb5ng-opencl in the git repo:

OpenCL platform 0: NVIDIA CUDA, 1 device(s).
Using device 0: GeForce GTX 570
Local worksize (LWS) 128, Global worksize (GWS) 131072
Benchmarking: Kerberos 5 AS-REQ Pre-Auth aes256-cts-hmac-sha1-96 [OpenCL]... (8xOMP) DONE
Raw:    37449 c/s real, 33182 c/s virtual

OpenCL platform 1: AMD Accelerated Parallel Processing, 2 device(s).
Using device 0: Tahiti
Local worksize (LWS) 256, Global worksize (GWS) 262144
Benchmarking: Kerberos 5 AS-REQ Pre-Auth aes256-cts-hmac-sha1-96 [OpenCL]... (8xOMP) DONE
Raw:    125728 c/s real, 270251 c/s virtual

I'm planning to add optional vectorizing to this format as well as wpapsk-opencl some day or the other. Max length of salt (username + realm) is 52 characters and max length of password is 64 characters. I have only tested it with the built-in test vectors though.

Enjoy,
magnum
