Robert Watson 597df30e62 Import OpenBSM 1.1p1 from vendor branch to 8-CURRENT, populating 
contrib/openbsm and a subset also imported into sys/security/audit.
This patch release addresses several minor issues:

- Fixes to AUT_SOCKUNIX token parsing.
- IPv6 support for au_to_me(3).
- Improved robustness in the parsing of audit_control, especially long
  flags/naflags strings and whitespace in all fields.
- Add missing conversion of a number of FreeBSD/Mac OS X errnos to/from BSM
  error number space.
