8b5fede0ac route(8): clarify -prefixlen description
Try to reword -prefixlen section to more clearly and accurately describe how
the -prefixlen modifier works.

While here, fix a word that igor considered a typo: aggregatable addresses is a
valid technical term per RFC-2374, however, it was superseded by the term
"aggregator" in RFC-3587.

9ec35e3cb4 Fix route manpage to show correct flush syntax
The current route(8) manpage shows that "flush" is an argument to
the optional -n flag, rather than a separate subcommand.  Correct
this to properly show flush as a route subcommand.

b3b6ff23e7 Allow route change requests to not specify the gateway.
Only require a gateway to be specified on a route add request.  On
a route change request that does not specify the gateway, the
gateway will remain the same.  This allows changing other route
parameters without having to re-specifying the gateway, like in
"route change 10.0.0.0/8 -mtu 9000".

Update the route(8) manpage to explicitly call out this usage
as being supported.

670e8b3b8c Kill custom in_matroute() radix mathing function removing one rte mutex lock.
Initially in_matrote() in_clsroute() in their current state was introduced by
r4105 20 years ago. Instead of deleting inactive routes immediately, we kept them
in route table, setting RTPRF_OURS flag and some expire time. After that, either
GC came or RTPRF_OURS got removed on first-packet. It was a good solution
in that days (and probably another decade after that) to keep TCP metrics.
However, after moving metrics to TCP hostcache in r122922, most of in_rmx
functionality became unused. It might had been used for flushing icmp-originated
routes before rte mutexes/refcounting, but I'm not sure about that.

So it looks like this is nearly impossible to make GC do its work nowadays:

in_rtkill() ignores non-RTPRF_OURS routes.
route can only become RTPRF_OURS after dropping last reference via rtfree()
which calls in_clsroute(), which, it turn, ignores UP and non-RTF_DYNAMIC routes.

Dynamic routes can still be installed via received redirect, but they
have default lifetime (no specific rt_expire) and no one has another trie walker
to call RTFREE() on them.

So, the changelist:
* remove custom rnh_match / rnh_close matching function.
* remove all GC functions
* partially revert r256695 (proto3 is no more used inside kernel,
  it is not possible to use rt_expire from user point of view, proto3 support
  is not complete)
* Finish r241884 (similar to this commit) and remove remaining IPv6 parts

45c203fce2 Remove AppleTalk support.
AppleTalk was a network transport protocol for Apple Macintosh devices
in 80s and then 90s. Starting with Mac OS X in 2000 the AppleTalk was
a legacy protocol and primary networking protocol is TCP/IP. The last
Mac OS X release to support AppleTalk happened in 2009. The same year
routing equipment vendors (namely Cisco) end their support.

Thus, AppleTalk won't be supported in FreeBSD 11.0-RELEASE.

2c284d9395 Remove IPX support.
IPX was a network transport protocol in Novell's NetWare network operating
system from late 80s and then 90s. The NetWare itself switched to TCP/IP
as default transport in 1998. Later, in this century the Novell Open
Enterprise Server became successor of Novell NetWare. The last release
that claimed to still support IPX was OES 2 in 2007. Routing equipment
vendors (e.g. Cisco) discontinued support for IPX in 2011.

Thus, IPX won't be supported in FreeBSD 11.0-RELEASE.

1d36c8992d When changing an indirect route, kernel routing code allocates
a route to the gateway and caches it in the route structure.
It may happen (if the routing table is screwed) that the gateway
route is the same route as the one being modified, in which case
a kernel reports EDQUOT.  Be more verbose about this:

# route add -net 10 192.168.4.65
add net 10: gateway 192.168.4.65
# netstat -rn -finet
