Keep my dirty paws off of the $NetBSD$ id's. They're tabbed and should
remain so.

Aesthetics: fix placement of $NetBSD$ (use space instead of tab)

Add $FreeBSD$ to the files which didn't have it yet.

Fix the .c files, so that the $FreeBSD$ is contained within the rcsid. [bde]

This commit was generated by cvs2svn to compensate for changes in r12099,
which included commits to RCS files with non-trunk default branches.

Jochen Pohl's lint(1) from NetBSD. Yet another import.

This is just a vendor import by now. I'll wait until i'll get the
imported files back via CTM before applying the FreeBSD patches.
Don't use it yet.
