> Not all of the above branch is to be merged right now; the UMA_ALLOC harvester bit will NOT be merged. In follow-up discussions, I will work out how to do this properly. Right now, that code works, but will no doubt piss off RWatson and company for messing up the carefully optimised slab allocator! :-)
> 
> In the first merge, very little change should be observed. ‘sysctl kern.random’ will look different as the harvesting has been slightly generalised. Yarrow will still be used, but Fortuna will be available as an alternative. Automatic startup due to probing entropy is tested and more-or-less trusted (analysis of numbers to form part of a more academic study).
> 
> The code is much simplified, and use of overly complex data structures has been rewritten.

> I request review and comments please, with a view to merging this to CURRENT.
