-mdoc sweep.

Add a sysctl to change to length of the quotation of the original
packet in an ICMP reply. The minimum of 8 bytes is internally
enforced. The maximum quotation is the remaining space in the
reply mbuf.

This option is added in response to the issues raised in I-D
draft-gont-icmp-payload-00.txt.

Add an option to have ICMP replies to non-local packets generated with
the IP address the packet came through in. This is useful for routers
to show in traceroutes the actual path a packet has taken instead of
the possibly different return path.

The new sysctl is named net.inet.icmp.reply_from_interface and defaults
to off.

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

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...

Revert $FreeBSD$ back 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.

Sort cross references.

Correct some man page xrefs, and some other minor changes to bring some
man pages up to mdoc guidelines and fix some minor formatting glitches.
Also fixed a number of man pages to not abuse the .Xr macro to
display functions and path names and a lot of other junk.
