Version 5 (2.6.23-rc8-mm2) Smack: Simplified Mandatory Access Control Kernel

I have broken the Smack patch into the netlabel changes from Paul Moore (1/2) and the Smack LSM (2/2), at Paul's kind suggestion.

The smackfs symlinks have proven too contentious. I have removed the facility. Al and Alan are correct that the rich set of mount options currently available can handle any of the use cases I was looking at without excessive difficulty.

I think that is the last of the major issues. I'm sure that if there are more y'all will let me know.

Thank you.
