* Address review (and add a bit myself).

 - Tweek man page.
 - Remove all mention of RANDOM_FORTUNA. If the system owner wants YARROW or DUMMY, they ask for it, otherwise they get FORTUNA.
 - Tidy up headers a bit.
 - Tidy up declarations a bit.
 - Make static in a couple of places where needed.
 - Move Yarrow/Fortuna SYSINIT/SYSUNINIT to randomdev.c, moving us towards a single file where the algorithm context is used.
 - Get rid of random_*_process_buffer() functions. They were only used in one place each, and are better subsumed into those places.
 - Remove *_post_read() functions as they are stubs everywhere.
 - Assert against buffer size illegalities.
 - Clean up some silly code in the randomdev_read() routine.
 - Make the harvesting more consistent.
 - Make some requested argument name changes.
 - Tidy up and clarify a few comments.
 - Make some requested comment changes.
 - Make some requested macro changes.

* NOTE: the thing calling itself a 'unit test' is not yet a proper
  unit test, but it helps me ensure things work. It may be a proper
  unit test at some time in the future, but for now please don't make
  any assumptions or hold any expectations.
