Behaviorally this port should already be largely on par with the
NetBSD 8 version, in that it sets the RTF_LLDATA flag on routing
socket requests to indicate that they target link-local data.
Many parts of the arp(8) functionality are currently not yet supported
by the operating system, largely due to lwIP not exposing appropriate
means of implementing them.

The port forces the use of sysctl(7), as obtaining information through
KVM is not and will never be viable. The sysctl mode of netstat(1) is
currently somewhat limited and buggy, though. We fix a few minimal
issues, but more improvements will have to come from NetBSD reimports.
Some of netstat(1)'s views are currently not supported by the
operating system. Later improvements on this point will not require
changes to the imported code, though.

Not all of its functionality is actually implemented in the operating
system. In addition, a few modules (agr, vlan) have been disabled
because we have not imported the necessary headers yet.

Also retire support for the MINIX versions of /etc/hosts and
/etc/resolv.conf. These files will be brought back with NetBSD
imports, although like NetBSD, MINIX 3 will be using external
resolvers directly from then on. Since resolv.conf is hand-created
rather than installed, we do not mark it as obsolete.

This commit (temporarily) leaves MINIX 3 without a TCP/IP service.
Thanks go out to Philip Homburg for providing this TCP/IP stack in the
first place. It has served MINIX well for a long time.

This needs to be done before retiring inet itself, since these
utilities include headers from inet directly.
Also retire the now-obsolete paramvalue(3).

This new implementation of the UDS service is built on top of the
libsockevent library. It thereby inherits all the advantages that
libsockevent brings. However, the fundamental restructuring
required for that change also paved the way for resolution of a
number of other important open issues with the old UDS code. Most
importantly, the rewrite brings the behavior of the service much
closer to POSIX compliance and NetBSD compatibility. These are the
most important changes:
- due to the use of libsockevent, UDS now supports multiple suspending
calls per socket and a large number of standard socket flags and
options;
- socket address matching is now based on <device,inode> lookups
instead of canonized path names, and socket addresses are no longer
altered either due to canonization or at connect time;
- the socket state machine is now well defined, most importantly
resolving the erroneous reset-on-EOF semantics of the old UDS, but
also allowing socket reuse;
- sockets are now connected before being accepted instead of being
held in connecting state, unless the LOCAL_CONNWAIT option is set
on either the connecting or the listening socket;
- connect(2) on datagram sockets is now supported (needed by syslog),
and proper datagram socket disconnect notification is provided;
- the receive queue now supports segmentation, associating ancillary
data (in-flight file descriptors and credentials) with each segment
instead of being kept fully separately; this is a POSIX requirement
(and needed by tmux);
- as part of the segmentation support, the receive queue can now hold
as many packets as can fit, instead of one;
- in addition to the flags supported by libsockevent, the MSG_PEEK,
MSG_WAITALL, MSG_CMSG_CLOEXEC, MSG_TRUNC, and MSG_CTRUNC send and
receive flags are now supported;
- the SO_PASSCRED and SO_PEERCRED socket options are replaced by
LOCAL_CREDS and LOCAL_PEEREID respectively, now following NetBSD
semantics and allowing use of NetBSD libc's getpeereid(3);
- memory usage is reduced by about 250 KB due to centralized in-flight
file descriptor tracking, with a limit of OPEN_MAX total rather than
of OPEN_MAX per socket;
- memory usage is reduced by another ~50 KB due to removal of state
redundancy, despite the fact that socket path names may now be up to
253 bytes rather than the previous 104 bytes;
- compared to the old UDS, there is now very little direct indexing on
the static array of sockets, thus allowing dynamic allocation of
sockets more easily in the future;
- the UDS service now has RMIB support for the net.local sysctl tree,
implementing preliminary support for NetBSD netstat(1).

IMPORTANT: this change has a docs/UPDATING entry!
This patch performs an initial import of the infrastructure and a
subset of the NetBSD set of rc startup and shutdown scripts. The
"initial" refers to the fact that this is not yet a full switch to the
NetBSD rc system: the MINIX ramdisk rc script, which (typically) runs
as the first thing, is kept as is. After mounting the root file
system, the ramdisk rc script will start the NetBSD rc infrastructure
by invoking /etc/rc, however. The regular MINIX startup-and-shutdown
script has been moved from /etc/rc to /etc/rc.minix, and is now
invoked as part of the NetBSD rc infrastructure through a bridge rc
script /etc/rc.d/minixrc. /etc/rc.minix invokes /usr/etc/rc as before.
Switching over the ramdisk to the NetBSD system and decomposing the
MINIX rc.minix script into smaller components are left to future work.
Also, the current pkgsrc etc/rc.d auto-start functionality is left as
is, even though it should be removed (see the etc/usr/rc comment).

This requires importing a few files from mail(1) already. Importing
the rest of mail(1) is left to future work.

IMPORTANT: this change has a docs/UPDATING entry!
This rename is unfortunately necessary because NetBSD has decided to
create its own service(8) utility, and we will want to import theirs
as well. The two can obviously not coexist.
Also move ours from /bin to /sbin, as it is a superuser-only utility.

Without this file, the NetBSD userland will fall back by default to the
old, insecure classic UNIX password hashing algorithm.
This is a big security issue. Please check docs/UPDATING for details.

The way these options work is by creating files that contain debugging
symbols and stashing them in a dedicated set. The minix-debug set has
been created for this purpose, but it will probably have to be refined
since it has been tested only with the default options with an i386
cross-build.
LSC: Amended to support many combination of MKDEBUG, MKDEBUGLIB, with
and without X11, for both intel and arm.

If this directory doesn't exist, pid files are not created, which create
issues when shutting down or rebooting.

Due to differences in (mainly) measuring and accumulating CPU times,
the two top programs end up serving different purposes: the NetBSD
top is a system administration tool, while the MINIX3 top (now mtop)
is a performance debugging tool. Therefore, we keep both.
The newly imported BSD top has a few MINIX3-specific changes. CPU
statistics separate system time from kernel time, rather than kernel
time from time spent on handling interrupts. Memory statistics show
numbers that are currently relevant for MINIX3. Swap statistics are
disabled entirely. All of these changes effectively bring it closer
to how mtop already worked as well.

No changes except for one cosmetic adjustment: NetBSD has chosen to
rename the standard TT column to TTY and not shorten tty names; we
undo those changes, making ps(1) behave more in accordance with the
specification and its manual page, and, most importantly for us, not
use an incredibly wide TTY column to print "console".

Adapt libc devname(3) to make use of it, so that such device name
queries are now several orders of magnitude faster. The database
is created and updated at system bootup time.
