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 library provides an event-based abstraction model and dispatching
facility for socket drivers. Its main goal is to eliminate any and
all need for socket drivers to keep track of pending socket calls.
Additionally, this library takes over responsibility of a number of
other tasks that would otherwise be duplicated between socket drivers,
but in such a way that individual socket drivers retain a large degree
of freedom in terms of API behavior. The library's main features are:
- suspension, resumption, and cancellation of socket calls;
- an abstraction layer for select(2);
- state tracking of shutdown(2);
- pending (asynchronous) errors and the SO_ERROR socket option;
- listening-socket tracking and the SO_ACCEPTCONN socket option;
- generation of SIGPIPE signals; SO_NOSIGPIPE, MSG_NOSIGNAL;
- send and receive low-watermark tracking, SO_SNDLOWAT, SO_RCVLOWAT;
- send and receive timeout support and SO_SNDTIMEO, SO_RCVTIMEO;
- an abstraction layer for the SO_LINGER socket option;
- tracking of various on/off socket options as well as SO_TYPE;
- a range of pre-checks on socket calls that are required POSIX.
In order to track per-socket state, the library manages an opaque
"sock" object for each socket. The allocation of such objects is left
entirely to the socket driver. Each sock object has an associated
callback table for calls from libsockevent to the socket driver. The
socket driver can raise events on the sock object in order to flag
that any previously suspended operations of a particular type should
be resumed. The library may defer processing such raised events if
immediate processing could interfere with internal consistency.
The sockevent library is layered on top of libsockdriver, and should
be used by all socket driver implementations if at all possible.

This library provides abstractions for socket drivers, and should be
used as the basis for all socket driver implementations. It provides
the following functionality:
- a function call table abstraction, hiding the details of the
socket driver protocol with simple parameters and presenting the
socket driver with callback functions very similar to the BSD
socket API calls made from userland;
- abstracting data structures and helper functions for suspending
and resuming blocking calls;
- abstracting data structures and helper functions for copying data
from and to the caller.
Overall, the library is similar to lib{block,char,fs,input,net}driver
in concept. Some of the abstractions provided here should in fact be
applied to libchardriver as well. As always, for the case that the
provided message loop is too restrictive, a set of more low-level
message processing functions is provided.

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.

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.
