as deprecated and points the reader to the newer pages.

Replace manual pages that may have violated the IETF's Copyright.
All come from the Kame tree.
Several were from OpenBSD except for ip6.4, and the inet6* pages which were
rewritten by me.
All of the text is new and drawn from reading the code and
documentation.

Remove files in preparation for replacement with totally new versions
of the manual pages.
Update the Makefile to handle the new file to be added.
Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
entire enclosed block.
