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.

The expiration specification can be one value or two values with the
logical conjunction of AND/OR between them.
Values for the audit log file age are numbers with the following
suffixes:
.Pp
.Bl -tag -width "(space) or" -compact -offset indent

.It Li h
Log file age in hours.
.It Li d

Values for the disk space used are numbers with the following suffixes:
.Pp
.Bl -tag -width "(space) or" -compact -offset indent
.It (space) or

.It Li K
Disk space used in Kilobytes.

The suffixes on the values are case sensitive.
If both an age and disk space value are used they are seperated by
AND or OR and both values are used to determine when audit
log files expire.
In the case of AND, both the age and disk space conditions must be meet
before the log file is removed.
In the case of OR, either condition may expire the log file.
