We've ifdef'd out the copyright strings for some time now. Go ahead and remove the ifdefs. Plus whatever other detritis was left over from other recent removals. These copyright strings are present in the comments and are largely from CSRG's attempt at adding their copyright to every binary file (which modern interpretations of the license doesn't require).
