While debugging issues with the VDS server I made the
driver use partition 2 to get at the whole disk since
this is the "whole disk" partition in the Sun disk
label.
We really should use slice 0xff which really means
the whole physical disk in the VIO disk protocol.
Otherwise things won't work well on a disk image
that doesn't have a proper disk label on it.

Some of the code has been gradually transitioned to using the proper
struct request_queue, but there's lots left. So do a full sweet of
the kernel and get rid of this typedef and replace its uses with
the proper type.

The "id" property in vdc-port nodes are not unique, they
are all zero. Therefore assign ID's using the parent's
"cfg-handle" property which will be unique.

Since we have to be able to handle MD updates, having an in-tree
set of data structures representing the MD objects actually makes
things more painful.
The MD itself is easy to parse, and we can implement the existing
interfaces using direct parsing of the MD binary image.
The MD is now reference counted, so accesses have to now take the
form:
handle = mdesc_grab();
... operations on MD ...
mdesc_release(handle);
The only remaining issue are cases where code holds on to references
to MD property values. mdesc_get_property() returns a direct pointer
to the property value, most cases just pull in the information they
need and discard the pointer, but there are few that use the pointer
directly over a long lifetime. Those will be fixed up in a subsequent
changeset.
A preliminary handler for MD update events from domain services is
there, it is rudimentry but it works and handles all of the reference
counting. It does not check the generation number of the MDs,
and it does not generate a "add/delete" list for notification to
interesting parties about MD changes but that will be forthcoming.
