ima: audit log hashes
This adds an 'audit' policy action which audit logs file measurements.
Changelog v6:
- use new action flag handling (Dmitry Kasatkin).
- removed whitespace (Mimi)
Changelog v5:
- use audit_log_untrustedstring.
Changelog v4:
- cleanup digest -> hash conversion.
- use filename rather than d_path in ima_audit_measurement.
Changelog v3:
- Use newly exported audit_log_task_info for logging pid/ppid/uid/etc.
- Update the ima_policy ABI documentation.
Changelog v2:
- Use 'audit' action rather than 'measure_and_audit' to permit
auditing in the absence of measuring..
Changelog v1:
- Initial posting.
