For legacy support no suffix defaults to bytes. - Audit trail log expiration support added. It is configured in audit_control(5) with the expire-after parameter. If there is no expire-after parameter in audit_control(5), the default, then the audit trail files are not expired and removed. See audit_control(5) for more information. - Change defaults in audit_control: warn at 5% rather than 20% free for audit partitions, rotate automatically at 2mb, and set the default policy to cnt,argv rather than cnt so that execve(2) arguments are captured if AUE_EXECVE events are audited. These may provide more usable defaults for many users. - Use au_domain_to_bsm(3) and au_socket_type_to_bsm(3) to convert au_to_socket_ex(3) arguments to BSM format. - Fix error encoding AUT_IPC_PERM tokens.
