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.

mode. This addresses a well-known race condition that can cause
servers to hang in accept(). The relevant case is when somebody
connects to the server and then immediately kills the connection
by sending a TCP reset. On the server this causes select to report
a ready condition on the socket, after which the accept call blocks
because there is no longer any pending connection to accept.
In -current there is already a work-around for this in the kernel.
It was merged into -stable some time ago, but then David Greenman
reverted it because it seemed to be causing a socket leak in some
cases. (See uipc_socket.c revision 1.51.2.3.) Hence this userland
fix is needed in -stable, and I plan to merge it into that branch
soon because it fixes a potential DoS attack. It may also be needed
in -current if the suspected socket leak turns out to be real. In
any case, after thinking it over I believe the fix belongs in
userland. An application shouldn't assume that a ready return from
select guarantees that the subsequent I/O operation cannot block.
A lot can happen between the select and the accept.
A similar fix should most likely be applied to the Unix domain
socket transport too.

It used to loop back up to the accept() call and block there,
shutting out all other transports until a new connection came in.
Now it returns instead after dropping the connection. That will
take it back to the select() loop where all transports can be
serviced. I intend to MFC this within a day or two since it
fixes a DoS vulnerability.
This fixes some nasty procfs problems for SMP, makes ps(1) run much faster,
and makes ps(1) even less dependent on /proc which will aid chroot and
jails alike.
To disable this facility and revert to previous behaviour:
sysctl -w kern.ps_arg_cache_limit=0

All Makefiles now use MACHINE_ARCH for the target architecture.
Unification is required for cross-building.
