This series of patches reorganizes the comedi core module somewhat. My
main aim was originally to implement proper reference counting for
comedi devices and get rid of various race conditions related to removal
of devices. I haven't got that far yet due to time constraints but I
have got as far as simplifying the data structures used by the core,
eliminating the `struct comedi_file_info` type, which seems like a
natural break point. I plan to come back to the reference counting
stuff later, but have real (payed) work to do in the meantime and I
don't want my existing patches to go stale. (Besides, this series of
patches is starting to get a bit long already!)
