Last bits of SCCS, RCS, CVS and Subversion IDs

So I plan on just removing the SCCS, RCS, CVS and Subversion Ids that
remain in the tree. Though I removed 32k $FreeBSD$ lines, there's about 100
or so remaining, and a few hundred miscellaneous other IDs. I do plan on
keeping the $NetBSD$ and $OpenBSD$ lines for now, though.

Comments?
