audit: fix event coverage of AUDIT_ANOM_LINK
The userspace audit tools didn't like the existing formatting of the AUDIT_ANOM_LINK event. It needed to be expanded to emit an AUDIT_PATH event as well, so this implements the change. The bulk of the patch is moving code out of auditsc.c into audit.c and audit.h for general use. It expands audit_log_name to include an optional "struct path" argument for the simple case of just needing to report a pathname. This also makes audit_log_task_info available when syscall auditing is not enabled, since it is needed in either case for process details.
