Cleanup of userland __P use

Remove the -DFAST_IPSEC from Makefiles again.

This was needed during the IPSEC->FAST_IPSEC->IPSEC transition
period to not break the build after picking up netipsec header
files. Now that the FAST_IPSEC kernel option is gone and the
default is IPSEC again those defines are superfluous.

This commit includes all remaining changes for the time being including

mdoc(7) police: join split punctuation to macro calls.

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.

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.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

mdoc(7) police: split punctuation characters + misc fixes.

Prepare for mdoc(7)NG.

mdoc(7) police: use canonical form of .Dd macro.

Change the spelling of `.' to `.' from .OBJDIR since `.' really is where
generated files land. Also give precedence to generated files.

The GCC 2.96 snapshots have slightly different rules for finding include
files. Mostly -I${.CURDIR} was needed -- especially for YACC generated
files as the new cpp does not look in the ultimate source file
(ie, the .y file)'s directory as told by the "#line" directive. Some were
misspellings of "-I${.CURDIR}" as "-I.".

Format string paranoia

mdoc(7) police: use certified section headers wherever possible.

Remove more single-space hard sentence breaks.

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.
