Sorry, I should have written to you earlier... although I think this stuff
is easier by IRC.

Anyway, I think the abstractions are bad.  Basically, you separated the
code by what was convienient to do.

I think we should do something similar to the way disk.c and disk_*.c work.
The main difference is we don't need to support multiple platforms
simultaneously, in the one binary.  This is basically an abstract class.

So, I propose that we have 3 files: device.c, device_linux.c, device_gnu.c
(BTW, why not device_hurd.c?)

Second, we have an API between device.c and device_*.c.  This will hopefully
be pretty much one way, but the general convention is: private functions
in device.c that we want device_*.c to see we call _ped_device_*(), and
_arch_device_*() in device_*.c

ped_device_stat(), ped_device_probe_all() and _do[_refresh]_{open,close} should
be moved into os-dependent code.

So, the arch interface is something like:

the private _ped_device() interface would be:

The PedDevice interface in <parted/device.h> would be unchanged.
