Robert Watson 06edd2f1e8 Merge OpenBSM 1.1 beta 1 from OpenBSM vendor branch to head, both 
contrib/openbsm (svn merge) and src/sys/{bsm,security/audit} (manual
merge).

OpenBSM 1.1 beta 1

- The filesz parameter in audit_control(5) now accepts suffixes: 'B' for
  Bytes, 'K' for Kilobytes, 'M' for Megabytes, and 'G' for Gigabytes.
  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.
