Reapply some local fixes that got lost with another NetBSD merge,

Fixed the fatal bug: CFLAGS should be added to, not overridden.
This prevented CPU and optimization flags to be added here.

- poll(2) support.
- simplify by strdup.
- set ai_protocol in hints to TCP.
- g/c FAITH_NS (no description, not maintained for years)
- warn if connection from IPv4 mapped is reached.

mdoc(7) police:

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.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

Remove GCC'isms in CFLAGS.

Remove whitespace at EOL.

mdoc(7) police: eliminate warnings, fix markup.

Sync with recent KAME.
This work was based on kame-20010528-freebsd43-snap.tgz and some
critical problem after the snap was out were fixed.
There are many many changes since last KAME merge.

TODO:
- The definitions of SADB_* in sys/net/pfkeyv2.h are still different
from RFC2407/IANA assignment because of binary compatibility
issue. It should be fixed under 5-CURRENT.
- ip6po_m member of struct ip6_pktopts is no longer used. But, it
is still there because of binary compatibility issue. It should
be removed under 5-CURRENT.
