hdparm, changing the hard-disk spindown (sleep time)

This is a very rough and ready patch.

To finally drive a nail in the coffin for the bodge that is PowerManager
dbus daemon, this is a quick patch to add a:

org.freedesktop.Hal.Device.SystemPowerManagement.SetSpindown (seconds)

method to all hard disks. This lets us abstract the detail of hdparm
(and its weird ID mapping) and lets any application use the spindown
sleep method.

I understand that SetLowPowerMode may do this sort of thing there, but
it made sense to use HAL to call a HAL method, if you see what I mean.

Plus it gives other programs the fine-grained spindown control.

What do ppl think? Is there an easy (cross-distro) way of calling
