pkgsrc RC scripts

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

Hi all,
I am consider to make the RC script support in pkgsrc a bit more useful
out of the box with the following changes:

(1) Install pkgsrc RC scripts by default into /etc/rc.pkg.d, not
/etc/rc.d and adjust the default value for rc_directories accordingly.
This keeps the logical separation between base and pkgsrc RC scripts
and still allows /usr (or /usr/pkg) to be on a separate filesystem.

(2) Provide a default value of NO for the control variables. This
ensures that no stupid "Missing variable $foo" clutters up the boot
messages.

Comments?
