Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Make this WARNS 2 clean, and fix up the manual page:

Avoid implicit function calls by adding the proper include files.
Use const char copyright.
Fix some fprint formatting.

In the manual page:

Use the .Pa macro for filenames and locations.
Kill hard setence breaks.
Make use of the .Tn and .Dq macros.
Add some to text to the otherwise blank HISTORY section (taken from CVS).

Correct typos, mostly s/ a / an / where appropriate. Some whitespace cleanup,
especially in troff files.

$Id$ -> $FreeBSD$

Teach IPXrouted to handle the internal net properly.
PR: 9871
Submitted by: Boris Popov <bp@butya.kz>

Major IPXrouted rework.

In rt_change() remember to update the interface pointer otherwise we will
send the RIP packets to the wrong interface(s) in future.

Update the hash generator and increase the size of the hash tables.

Only use the network and host parts when comparing IPX interface addresses.

Immediately broadscast RIP and SAP changes.

Change the alarm code to use the setitimer() call and only set a flag in
the alarm signal handler. This gets rid of possible race conditions.

Remove the host routing table. IPX RIP cannot do host routes, only net routes.

Make the delay between broadcast packets 50ms. It seems that some Netware
4.x servers is very slow and don't have much input buffering.

Handle received messages about networks and services that go down, better.

Add tracing of RIP and SAP changes. It gets sysloged with a level of
LOG_DEBUG.

Don't depend on <machine/cpufunc.h> including <sys/types.h>. In fact,
don't include this kernel-only header at all, since we don't need it.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

John's IPXrouted..
this has not yet been seen to run correctly with Mike's IPX/SPX
code (he has his own)
bringing them both in is the first step in merging the two packages
for 2.2
