whitespace fixes, from Rob Pierce and me

update log.c in ifstated to the same used in bgpd etc.
Done by Rob Pierce <rob AT 2keys DOT ca>, thanks

remove bogus attributes from ifstated, spooted by guenther@

ok stsp@ claudio@ florian@

Convert the logic in yyerror(). Instead of creating a temporary
format string, create a temporary message.
OK claudio@

as done in ospf{,6}d/relayd, sync yyerror in various other daemons with
that from bgpd, so that it logs to syslog when daemonized.

remove assumption that internal IFSD_LINK* defines are the same as
LINK_STATE* defines in <net/if.h>, which were changed Sep 14. this
fixes link state down being treated as up.

ok claudio@ henning@

sync logging with most other daemons.

Clean up command line options:
- Make -v work as intended.
- Add -n to test config without doing anything.

Update to ifstated; replace parser, introduce the concept of states,
external tests, and boolean logic. Allows ifstated to handle partial
failures on firewalls that are CARPd to each other.
