/**
* \file
* ways to create uuid variant 5. For uuid of variant 1 I use
* the implementation delivered with the core utils.
* But this is wrapped in here, so that the rest of the code
* can use only this implementation...this additionally has the
* advantage that we can implement version 1 here too for systems
* where the coreutils implementation is not available.
