ng_pppoe(8): add support for user-supplied Host-Uniq tag.

A few ISP filter PADI requests based on such tag,
to force the use of their own routers.
The custom Host-Uniq tag is passed in the NGM_PPPOE_CONNECT
control message, so it can be used with FreeBSD ppp(8)
and mpd without any other change.

Add support to send and receive PADM messages,
HURL and MOTM, often used by service providers to provide
ACS information and other configuration settings
to the user CPE.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Make Netgraph compile with Clang.

Clang disallows structs with variable length arrays to be nested inside
other structs, because this is in violation with ISO C99. Even though we
can keep bugging the LLVM folks about this issue, we'd better just fix
our code to not do this. This code seems to be the only code in the
entire source tree that does this.

I haven't tested this patch by using the kernel modules in question, but
Diane Bruce and I have compared disassembled versions of these kernel
modules. We would have expected them to be exactly the same, but due to
randomness in the register allocator and reordering of instructions,
there were some minor differences.

- Import the HEAD csup code which is the basis for the cvsmode work.

Remove some prehistoric never used defines.

Fix ng_pppoe(4) after turning off "autosrc feature" on ng_ether(4).

- Store the Ethernet header in node softc.
- Initialize header with dst addr and ethertype in node
constructor method.
- In node connect method send NGM_ETHER_GET_ENADDR message
downwards.
- If received reply from ng_ether(4) store the src addr
in softc.
- Add NGM_PPPOE_SETENDADDR message that allows user to
override the address with whatever he/she wants.

o Introduce D-Link compat mode, that is default to off and can be set
by NGM_PPPOE_SETMODE message. When D-Link compat mode is on, we will
broadcast PADI with empty Service-Name to all listening hooks.
o Rewrite the compatibility options. Before we had two modes - standard
and non-standard (aka 3Com). Now we have standard mode and two compat
flags, that can be combined.
o Be consistent and do s/STUPID/3COM/g. I don't say that 3Com mode isn't
stupid, just want to make code easier to read.

Use variable-sized arrays where appropriate.

/* -> /*- for license, minor formatting changes

When node is server serve both standard RFC2516 and non-standard 3Com
clients simultaneously. When node is client its mode is configured
with a control message.

sysctl net.graph.nonstandard_pppoe is deprecated but kept for
backward compatibility for some time.

Get rid of the deprecated *LEN constants in favour of the new
*SIZ constants that include the trailing \0 byte.

Use a single style of multiple inclusion protection for Netgraph headers.

use __packed.

Fix GCC warnings caused by initializing a zero length array. In the process,
simply things a bit by getting rid of 'struct ng_parse_struct_info' which
was useless because it only contained one field.

Add a NGM_PPPOE_SESSIONID message to the ng_pppoe node.
This message is sent to the control socket when the SessionID
is established.

Shuffle sysctls a bit (thankyou whoever made them dynamic for modules)
and add a sysctl to pppoe to activate non standard ethertypes
so that idiot ISPs (apparently in France) who use
equipment from idiot suppliers (rumour says 3com)
who use nonstandard ethertypes can still connect.

"yep, sure we do pppoe, we use a different identifier to that dictated in
the standard, but sure it's pppoe!"

sysctl -w net.graph.stupid_isp=1 enables the changeover.

I have no idea at all why this file was not included in the last commit.

Go back to using data_len in struct ngpppoe_init_data after discussions
with Julian and Archie.

Implement a new ``sizedstring'' parse type for dealing with field pairs
consisting of a uint16_t followed by a data field of that size, and use
this to deal with the data_len and data fields.

Written by: Archie with some input by me
Agreed in principle by: julian

Change the format of ngpppoe_init_data so that the provider is NUL
terminated and the data_len field is no longer necessary.

Add ASCII2BINARY and BINARY2ASCII capabilities.

The old format is still understood and dealt with, but can't do
the ASCII2BINARY and BINARY2ASCII stuff.

Since neither archie nor I work at Whistle any more, change our email
addresses to be the more usefu @freebsd.org ones
so we can keep getting bug-reports.

Start making the contents of the generic framework opaque to the nodes.
This step: IDs are no-longer the address of the node.

change PPPoE occurences to pppoe. Not JUST a cosmeting change.
some occurrances needed to be the same as the filenmnae which was pppoe
not PPPoE.

Now that Netgraph is in the system there are some cleanups we can do.
Also save a slightly closer to completion version of the PPPOE code.
