Robert Watson c0020399a6 Merge OpenBSM 1.1 from OpenBSM vendor branch to head. 
OpenBSM history for imported revision below for reference.

MFC after:      2 weeks
Sponsored by:   Apple, Inc.
Obtained from:  TrustedBSD Project

OpenBSM 1.1

- Change auditon(2) parameters and data structures to be 32/64-bit architecture
  independent.  Add more information to man page about auditon(2) parameters.
- Add wrapper functions for auditon(2) to use legacy commands when the new
  commands are not supported.
- Add default for 'expire-after' in audit_control to expire trail files when
  the audit directory is more than 10 megabytes ('10M').
- Interface to convert between local and BSM fcntl(2) command values has been
  added:  au_bsm_to_fcntl_cmd(3) and au_fcntl_cmd_to_bsm(3), along with
  definitions of constants in audit_fcntl.h.
- A bug, introduced in OpenBSM 1.1 alpha 4, in which AUT_RETURN32 tokens
  generated by audit_submit(3) were improperly encoded has been fixed.
- Fix example in audit_submit(3) man page.  Also, make it clear that we want
  the audit ID as the argument.
- A new audit event class 'aa', for post-login authentication and
  authorization events, has been added.
