rwatson 7e3aff1dc1 Merge OpenBSM 1.1 changes to the FreeBSD 8.x kernel:
- Add and use mapping of fcntl(2) commands to new BSM constant space.
- Adopt (int) rather than (long) arguments to a number of auditon(2)
  commands, as has happened in Solaris, and add compatibility code to
  handle the old comments.

Note that BSM_PF_IEEE80211 is partially but not fully removed, as the
userspace OpenBSM 1.1alpha5 code still depends on it.  Once userspace
is updated, I'll GCC the kernel constant.
