Update information on setting and retreiving inet4 addresses.

mdoc: drop redundant .Pp and .LP calls

They have no effect when coming in pairs, or before .Bl/.Bd

mdoc: move CAVEATS, BUGS and SECURITY CONSIDERATIONS sections to the
bottom of the manpages and order them consistently.

GNU groff doesn't care about the ordering, and doesn't even mention
CAVEATS and SECURITY CONSIDERATIONS as common sections and where to put
them.

Remove all references to T/TCP, which was removed several months ago.

Fixed xref.

Scheduled mdoc(7) sweep.

o Remove entire section talking about RTF_PRCLONING that got nuked in 5.2

Mdoc Janitor:

* cleanup hard sentence breaks.

* sprinle some .Dq macros.

Use more modern architectures than VAX for little endian machines

mdoc(7): Use the new feature of the .In macro.

Hiten's patchset for section four manpages, slightly edited by me.

Back out support for RFC3514.

RFC3514 poses an unacceptale risk to compliant systems.

Implement support for RFC 3514 (The Security Flag in the IPv4 Header).
(See: ftp://ftp.rfc-editor.org/in-notes/rfc3514.txt)

This fulfills the host requirements for userland support by
way of the setsockopt() IP_EVIL_INTENT message.

There are three sysctl tunables provided to govern system behavior.

net.inet.ip.rfc3514:

Enables support for rfc3514. As this is an
Informational RFC and support is not yet widespread
this option is disabled by default.

net.inet.ip.hear_no_evil

If set the host will discard all received evil packets.

net.inet.ip.speak_no_evil

If set the host will discard all transmitted evil packets.

The IP statistics counter 'ips_evil' (available via 'netstat') provides
information on the number of 'evil' packets recieved.

For reference, the '-E' option to 'ping' has been provided to demonstrate
and test the implementation.

Sync types with headers.

Mention net.inet.ip.accept_sourceroute.

mdoc(7) police: Use the new .In macro for #include statements.

Grammar: 'effect' is a noun and 'affect' is a verb.

Removed whitespace at end-of-line; no content changes. I simply did
cd src/share; find man[1-9] -type f|xargs perl -pi -e 's/[ \t]+$//'

BTW, what editors are the culprits? I'm using vim and it shows
me whitespace at EOL in troff files with a thick blue block...

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

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.
