in /sys describing each device in use.  This means that we can determine which
devices are in use without crawling through the store.

The physical-device node has been changed to give the major and minor of the
device, separated by a colon.  This means that we do not need to pack these
numbers into one, removing the restriction to 8 bit minors that we had in place
before.

The mode specified in the config file is now written explicitly to the store,
rather than using the presence or absence of a read-only node.  This supports
the write-sharing override above.

If the device is in use, a new hotplug status of "busy" is written to the
store, and a message is written to a new hotplug-error node.  Xend uses these
things for diagnosis.

The block scripts do not need to handle online or offline events, so this
support has been removed.  These scripts can be called twice, depending upon
the hotplug config, so they now identify the second run and do not attempt to
set up the device again.

The device directories in the store are cleaned out before new details are
written there.  This prevents stale information from messing up block device
hotplugging.  This will be one cause of "blkback: changing physical device
not supported" messages.
