various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

Implement an ``enable/disable echo'' option, defaults to off.
This allows LCP ECHOs to be enabled independently of LQR reports.

Note: This introduces a change in the default behaviour (search for lqr and
echo in the man page). I'll update UPDATING to reflect this.

o Clean up some #includes
o Bump version number to 3.0.4
o When talking to a RADIUS server, provide a NAS-Port-Type.

When the NAS-Port-Type is Ethernet, provide a NAS-Port value equal
to the SESSIONID from the environment in direct mode or the
NGM_PPPOE_SESSIONID message in other modes. If no SESSIONID is found,
default to the interface index in client mode or zero in server mode.

When the NAS-Port-Type is ISDN, set the NAS-Port to the minor number
of the physical device (ie, the N in /dev/i4brbchN).

This makes it easier for the RADIUS server to identify the client
WRT accounting data etc.

When the peer fails to specify an MRU and a 1500 byte MRU is not
allowed either because of the transport or configuration, send a
MRU NAK only once, then allow the negotiations to proceed.

rfc1661 says that 1500 should always be allowed and rfc2516 says
that 1492 is the maximum for PPPoE. This changes ppp so that it
only weakly suggests 1492, then goes with the default (leaving
the problem in the hands of the peer WRT how they set their MTU).

o Add ipv6 support, abstracting most NCP addresses into opaque
structures (well, they're treated as opaque).

It's now possible to manage IPv6 interface addresses and routing
table entries and to filter IPV6 traffic whether encapsulated or
not.

IPV6CP support is crude for now, and hasn't been tested against
any other implementations.

RADIUS and IPv6 are independent of eachother for now.

ppp.linkup/ppp.linkdown aren't currently used by IPV6CP

o Understand all protocols(5) in filter rules rather than only a select
few.

o Allow a mask specification for the ``delete'' command. It's now
possible to specifically delete one of two conflicting routes.

o When creating and deleting proxy arp entries, do it for all IPv4
interface addresses rather than doing it just for the ``current''
peer address.

o When iface-alias isn't in effect, don't blow away manually (via ``iface
add'') added interface addresses.

o When listening on a tcp server (diagnostic) socket, bind so that a
tcp46 socket is created -- allowing both IPv4 and IPv6 connections.

o When displaying ICMP traffic, don't display the icmp type twice.
When display traffic, display at least some information about unrecognised
traffic.

o Bump version

If the peer REJects our MRU REQ, stop REQing it -- *EVEN* if we're
doing PPPoE and the default MRU is therefore too big.

When negotiating with win2k, we ask for MRU 1492 and the win2k box
NAKs us saying ``MRU 1492''. This doesn't make sense to me. When
we continue to request MRU 1492, the win2k box eventually REJs our
MRU. This fix allows negotiations to continue at that point,
bringing the link up and potentially allowing the win2k box to send
us frames that are too large. AFAICT this is better than failing
to bring the link up.... probably !

I have no idea how to do the equivalent of ``route get'' or
``ifconfig -a'' under win2k, so I can't tell what MTU it actually
ends up using.

I believe the bug is in win2k (it's certainly mis-negotiating).
I'll MFC given the release engineers permission as code freeze
begins on August 1.
