Merge OpenBSM 1.2-alpha3 from head to stable/9, upgrading from the previous
OpenBSM 1.1p2:

OpenBSM 1.2 alpha 3

- Various minor tweaks to the auditdistd build to make it fit the FreeBSD
  build environment better.
- AUE_WAIT6 merged from FreeBSD 9.

OpenBSM 1.2 alpha 2

- auditdistd, a distributed audit trail management daemon, has now been
  merged.  This allows trail files to be securely and reliably synced from
  audited hosts to an audit server, and employs TLS encryption.  Where
  available, it uses Capsicum to sandbox the service.  This work was
  contributed by Pawel Jakub Dawidek under sponsorship from the FreeBSD
  Foundation.

OpenBSM 1.2 alpha 1

- Add Capsicum-related error numbers for FreeBSD: ENOTCAPABLE, ECAPMODE.
- Add Capsicum, process descriptor audit events for FreeBSD.
- Allow 0% minspace.
- Fixes from the clang static analyser.
- Fix expiration of trail files when the host parameter is used.
- Various typo fixes.
- Support for Solaris privilege and privilege set tokens.
- Documentation for getachost(), improvements for getacfilesz().
- Fix a directory descriptor leak that happened when audit trail partitions
  filled.
- Support for more Linux distributions with a partial contemporary endian.h.
- Improved escaping of XML-encapsulated BSM.
- A variety of minor documentation, style, and functional.

A separate commit will merge build changes to enable auditdistd, etc.
