rwatson c3c1c81918 Four .c files from OpenBSM are used, in modified form, by the kernel to
implement the BSM audit trail format.  Rename the kernel versions of the
files to match the userspace filenames so that it's easier to work out
what they correspond to, and therefore ensure they are kept in-sync.
