Vendor branch import of TrustedBSD OpenBSM 1.0 alpha 6:

- Use AU_TO_WRITE and AU_NO_TO_WRITE for the 'keep' argument to au_close();
  previously we used hard-coded 0 and 1 values.
- Add man page for au_open(), au_write(), au_close(), and
  au_close_buffer().
- Support a more complete range of data types for the arbitrary data token:
  add AUR_CHAR (alias to AUR_BYTE), remove AUR_LONG, add AUR_INT32 (alias
  to AUR_INT), add AUR_INT64.
- Add au_close_token(), which allows writing a single token_t to a memory
  buffer.  Not likely to be used much by applications, but useful for
  writing test tools.
- Modify au_to_file() so that it accepts a timeval in user space, not just
  kernel -- this is not a Solaris BSM API so can be modified without
  causing compatibility issues.
- Define a new API, au_to_header32_tm(), which adds a struct timeval
  argument to the ordinary au_to_header32(), which is now implemented by
  wrapping au_to_header32_tm() and calling gettimeofday().  #ifndef KERNEL
  the APIs that invoke gettimeofday(), rather than having a variable
  definition.  Don't try to retrieve time zone information using
  gettimeofday(), as it's not needed, and introduces possible failure
  modes.
- Don't perform byte order transformations on the addr/machine fields of
  the terminal ID that appears in the process32/subject32 tokens.  These
  are assumed to be IP addresses, and as such, to be in network byte
  order.
- Universally, APIs now assume that IP addresses and ports are provided
  in network byte order.  APIs now generally provide these types in
  network byte order when decoding.
- Beginnings of an OpenBSM test framework can now be found in openbsm/test.
  This code is not built or installed by default.
- auditd now assigns more appropriate syslog levels to its debugging and
  error information.
- Support for audit filters introduced: audit filters are dynamically
  loaded shared objects that run in the context of a new daemon,
  auditfilterd.  The daemon reads from an audit pipe and feeds both BSM and
  parsed versions of records to shared objects using a module API.  This
  will provide a framework for the writing of intrusion detection services.
- New utility API, audit_submit(), added to capture common elements of audit
  record submission for many applications.
