Simplify keywords.h generation.

route(8): make WARNS=3 clean

- add static and const where appropriate
- check pointers against NULL
- minor styling nits
- it is actually WARNS=6 clean for non-strict alignment platforms

This is shamelessly stolen from DragonflyBSD and reduces our diff.

Obey MK_INET6_SUPPORT.
This is also a good chance to apply style.Makefile(5) in some cases.

style.Makefile(5):
Use WARNS?= instead of WARNS=.

LANG->LC_ALL

Pointed by: ru

Fix problem differently, use 
LANG=C tr 'a-z' 'A-Z' 
for hypotetical case that script may generate non-ascii characters

Use tr '[:lower:]' '[:upper:]' to work with any locale

Removed the cruft that became cruft after rev. 1.4.
Fixed CLEANFILES.

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.

This patch allows true interface routing to be controlled
from the command line..
you can now do:
route add default -interface ppp0
even if you have no clue what the address at the other end is..

this is part of a set of changes that allow true "unnumbered links"
such as netcom run between their sites..
In practice you should assign the address from one of your ethernet
interfaces to the local side of the P2P link so that IP doesn't
say that the packet comes from 255.255.255.255, but
there is no need whatsoever to assign an address of any kind
to the remote end of the link.. useful for frame relay links etc also.

Remove support for OSI networking in user-land (#ifdef OSI aor CCITT)

Convert to our man installation style. Also fixed long-standing bug
in `fastboot'/`fasthalt' in which the interpreter would hang around
after `reboot' or `halt' is run, causing an irritating ``Killed'' message.

Remove old style manual page depends so make install with NOMAN set
can run.
