Warner Losh 5b31cc94b1 sccs: Manual changes
For the uncommon items: Go through the tree and remove sccs tags that
didn't fit any nice pattern. If in the neighborhood, other SCM tags were
removed when they were detritis of long-ago CVS somehow in the early
mists of the project. Some adjacent copyrights stringswere removed (they
duplicated the copyright notices in the file). This also removed
non-standard formations of omission of SCCS tags (usually by adding an
extra #if 0 somewhere.

After this commit, a number of strings tagged with the 'what' @(#)
prefix remain, but they are primarily copyright notices.
