Add static tracing for privilege checking:
priv:kernel:priv_check:priv_ok fires for granted privileges
priv:kernel:priv_check:priv_errr fires for denied privileges
The first argument is the requested privilege number. The naming
convention is a little different from the OpenSolaris equivilent
because we can't have '-' in probefunc names, and our privilege
namespace is different.
A typical tracing command might be:
dtrace -n 'priv:::priv_ok { trace(execname); trace(arg0);}'
arg0 requires manual interpretation using /usr/include/sys/priv.h.
