Subject: Pad the strings sccs[], version[], and osrelease[] up to a minimum of
 128 bytes, 256 bytes, and 32 bytes respectively.  This makes it much easier
 to identify when two kernels are identical apart from a version number bump
 (as often happens on security branches).

Discussed on:	freebsd-arch, in May 2005
