Configurable list of rc directories

[Joerg Sonnenberger <joerg%britannica.bec.de@localhost>]

Hi all,
the attached patch adds rc_directories to specify what directories to
look in for rc scripts. It defaults to /etc/rc.d, but can be overriden
to separate e.g. pkgsrc rc scripts from base scripts. It does not change
the fact that all rc scripts must be on the root filesystem.

Comments? I do intend to get this pulled up to netbsd-5.
