Add static DTrace probes for MAC Framework access control checks and
privilege grants so that dtrace can be more easily used to monitor
the security decisions being generated by the MAC Framework following
policy invocation.
Successful access control checks will be reported by:
mac_framework:kernel:<entrypoint>:mac_check_ok
Failed access control checks will be reported by:
mac_framework:kernel:<entrypoint>:mac_check_err
Successful privilege grants will be reported by:
mac_framework:kernel:priv_grant:mac_grant_ok
Failed privilege grants will be reported by:
mac_framework:kernel:priv_grant:mac_grant_err
In all cases, the return value (always 0 for _ok, otherwise an errno
for _err) will be reported via arg0 on the probe, and subsequent
arguments will hold entrypoint-specific data, in a style similar to
privilege tracing.
