0f49c96cfc accept(2): Update portability note for accept4().
The accept(2) man page warns that O_NONBLOCK and other properties on the
new socket may vary across implementations. However, this issue only
applies to accept() and not to accept4(). On the other hand, accept4()
is not commonly available yet.

da7d2afb6d Add accept4() system call.
The accept4() function, compared to accept(), allows setting the new file
descriptor atomically close-on-exec and explicitly controlling the
non-blocking status on the new socket. (Note that the latter point means
that accept() is not equivalent to any form of accept4().)

The linuxulator's accept4 implementation leaves a race window where the new
file descriptor is not close-on-exec because it calls sys_accept(). This
implementation leaves no such race window (by using falloc() flags). The
linuxulator could be fixed and simplified by using the new code.

Like accept(), accept4() is async-signal-safe, a cancellation point and
permitted in capability mode.

de9dcfba06 accept(2): Mention inheritance of O_ASYNC and signal destination.
While almost nobody uses O_ASYNC, and rightly so, the inheritance of the
related properties across accept() is a portability issue like the
inheritance of O_NONBLOCK.

4054af4fb0 Attempt to reduce accidental foot-shooting by pointing out that
accept(2)ed sockets do not necessarily inherit O_NONBLOCK from
listening sockets on non-FreeBSD platforms.

This updates some structures with other, almost equivalent types and
effort is under way to get the whole more consistent.

Also removes a double definition of INET6 and some other clean-ups.
