- Add a more detailed comment describing the mac_test policy.
- Add COUNTER_DECL() and COUNTER_INC() macros to declare and manage
various test counters, reducing the verbosity of the test policy
quite a bit.
- Add LABEL_CHECK() macro to abbreviate normal validation of labels.
Unlike the previous check macros, this checks for a NULL label and
doesn't test NULL labels. This means that optionally passed labels
will now be handled automatically, although in the case of optional
credentials, NULL-checks are still required.
- Add LABEL_DESTROY() macro to abbreviate the handling of label
validation and tear-down.
- Add LABEL_NOTFREE() macro to abbreviate check for non-free labels.
- Normalize the names of counters, magic values.
- Remove unused policy "enabled" flag.
