Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Catch up with many years of changes:

o Document PF_LOCAL as being an alias for PF_UNIX
o Document POSIX standardization of this interface using AF_*
constants rather than PF_* constants, and note the three particular
families which POSIX standardizes.
o Note anticipated POSIX standardization of SOCK_CLOEXEC.
o Delete from listing protocol families that FreeBSD doesn't support
(in some cases, like PF_PUP, has never supported).
o Add to listing some current protocol families that have been
introduced in the last decade or so.
o Document the correspondence of PF_* and AF_* constants.

We should probably change the documentation to make the AF_* constants
primary, but this commit does not do so.

Implement SOCK_CLOEXEC, SOCK_NONBLOCK and MSG_CMSG_CLOEXEC.

This change allows creating file descriptors with close-on-exec set in some
situations. SOCK_CLOEXEC and SOCK_NONBLOCK can be OR'ed in socket() and
socketpair()'s type parameter, and MSG_CMSG_CLOEXEC to recvmsg() makes file
descriptors (SCM_RIGHTS) atomically close-on-exec.

The numerical values for SOCK_CLOEXEC and SOCK_NONBLOCK are as in NetBSD.
MSG_CMSG_CLOEXEC is the first free bit for MSG_*.

The SOCK_* flags are not passed to MAC because this may cause incorrect
failures and can be done later via fcntl() anyway. On the other hand, audit
is expected to cope with the new flags.

For MSG_CMSG_CLOEXEC, unp_externalize() is extended to take a flags
argument.
