b1495183c8 my copyright: some minor adjustments 
- remove "all rights reserved" from my copyright on my extensive
  contributions
- belatedly add my name to tuning.7 which I was a large contributor to
  several years ago

This commit can also serve as implicit permission for any formatting or
non-substantive changes that FreeBSD wishes to make in the future.

c05bbe4d23 It's 2015, and some people are still trying to use fdisk and then 
go asking what debug flags to set for GEOM to make it work.  Advice
them to use gpart(8) instead.

Something similar should probably done with disklabel,
but I need to rewrite the disklabel examples first.
