audit patches

Misc audit patches (resend again...); the most intrusive one is AUDIT_FD_PAIR,
allowing to log descriptor numbers from syscalls that do not return them in
usual way (i.e. pipe() and socketpair()).  It took some massage of
the failure exits in sys_socketpair(); the rest is absolutely trivial.
