Add two features: log_in_vain: log_in_vain turns on logging for packets to ports for which there is no listener. rc.sysctl: A generic way to set sysctl values. It reads /etc/syslog.conf and sets values based on that. No /etc/syslog.conf has been checked in yet, and I've not added this to the makefile yet until I get more feedback.

- Add descriptions to most of the rc scripts. Those are mostly taken from their daemon's manpage and probably improved. - Consistently use "filesystem" not "file system".

rc.d/sysctl: Fix error messages about unknown OIDs. There are three situations where the sysctl script is called: 1. "start", very early 2. "lastload", near the end of rc 3. "reload", at admin request while the system is booted Ignore unknown OIDs in situation 1 because kernel modules may not be loaded yet and complain about them in situations 2 and 3.

Luke Mewburn has indicated that they (NetBSD) are not interested in keeping the scripts under rc.d in sync with us. So, remove NetBSD specific stuff (which made our scripts more complicated than necessary). The NetBSD ident string will be left intact, both for history and also incase we wish to pull in future versions. 2004-01-17 10:59:43 +00:00			`extra_commands="reload lastload"`
