There were a few accounting data/macros that are used in CSA
but are #ifdef'ed inside CONFIG_BSD_PROCESS_ACCT. This patch is
to change those ifdef's from CONFIG_BSD_PROCESS_ACCT to
CONFIG_CSA_ACCT. A few defines are moved from kernel/acct.c and
include/linux/acct.h to kernel/csa.c and include/linux/csa_kern.h.
