a Jail.

route: switch transport protocol to Netlink.

All known bugs have been fixed, try to enable Netlink once again.

route: revert transport to rtsock

Temporary switch route(8) back to using rtsock to address
the discovered issues.

route(8): convert to netlink

This change converts all kernel rtsock interactions in route(8)
to Netlink.

Based on the WITHOUT_NETLINK_SUPPORT src.conf(5) variable, route(8)
now fully operates either via Netlink or via rtsock/sysctl.
The default (compile-time) is Netlink.

The output for route delete/add/get/flush is targeted to be exactly
the same (apart from some error handling cases).
The output for the route monitor has been changed to improve
readability and support netlink models.

Other behaviour changes:
* exact prefix lookup (route -n get a.b.c.d/e) is not yet supported.
* route monitor does not show the change originator yet.

Add tests for "add", "change" and "delete" functionality of /sbin/route.

Add tests to cover "add", "change" and "delete" functionality of /sbin/route
for ipv4 and ipv6. These tests for the existing route tool are the first step
towards creating libroute.

Check in first src/tests snapshot from NetBSD anoncvs

Sources were obtained like so:

% export CVSROOT="anoncvs@anoncvs.NetBSD.org:/cvsroot"
% cvs -z9 co -D "09/30/2014 20:45" -P src/tests
% mv src/tests/* tests/dist/.

'*CVS*' has been added to svn:ignore to ease updating periodically from
upstream

Some line ending issues had to be resolved with test outputs and scripts
via dos2unix and by deleting the eol-style property set in usr.bin/sort

Use src.opts.mk in preference to bsd.own.mk except where we need stuff
from the latter.

- Add support of MK_INET_SUPPORT=no.
- Fix a bug in sodump() which prevented struct sockaddr_in6 from displaying.
- Fix a bug in in fiboptlist_csv() which could cause free() of uninitialized
pointer.
- Style cleanups:
. Add missing "static" keywords.
. Use an array of struct sockaddr_storage instead of sockunion for rtmsg.
. Use err() and errx() instead of pair of fprintf(stderr, "...") + exit(1).
. Use nitems() macro.
. Various style(9) fixes.

Simplify keywords.h generation.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

route(8): make WARNS=3 clean

- add static and const where appropriate
- check pointers against NULL
- minor styling nits
- it is actually WARNS=6 clean for non-strict alignment platforms

This is shamelessly stolen from DragonflyBSD and reduces our diff.

This patch allows true interface routing to be controlled
from the command line..
you can now do:
route add default -interface ppp0
even if you have no clue what the address at the other end is..

this is part of a set of changes that allow true "unnumbered links"
such as netcom run between their sites..
In practice you should assign the address from one of your ethernet
interfaces to the local side of the P2P link so that IP doesn't
say that the packet comes from 255.255.255.255, but
there is no need whatsoever to assign an address of any kind
to the remote end of the link.. useful for frame relay links etc also.
