Bluetooth expects the following:
1 - that obsolete variables aren't used any more in /etc/rc.conf. Not my
case.
2 - in case they are, warn user and ask him to update to bluetooth=YES.

Functionally, yes, it looks the same. However, Martin wanted me to add a
condition that renders the check silent if the user explicitly set
powerd=NO (or anything functionally equivalent) in /etc/rc.conf.

Problem: given the way /etc/rc.conf is designed, it will first include
/etc/defaults/rc.conf:

http://nxr.netbsd.org/xref/src/etc/rc.conf

How am I supposed to parse /etc/rc.conf via eval without polluting the
environment with default values? Given that /etc/defaults/rc.conf sets
powerd=NO by default: fail. And implementing a half-backed solution with
regexps is an ugly hack.
