This updates the udhcpc support to use busybox's udhcpc instead of the
stand alone version.
I would like to thank jackieku <kjackie@gmail.com> for assisting with

OpenRC version is now stored as plaintext in /libexec/rc/version
Plugins (cursplash, splashutils) will have to be re-compiled to pickup
the new directories. State data needs to be moved from /lib/rc/init.d
to /libexec/rc/init.d as well.
