Staging: add comedi core
This adds the Comedi core to the staging tree.
This is a data acquision infrastructure for Linux, providing a common
interface for these types of drivers.
Taken directly from the comedi git tree, with only minor tweaks
by Greg to get it to build properly within the kernel tree.
