Paul Durrant (18):
xen: re-name XenDevice to XenLegacyDevice...
xen: introduce new 'XenBus' and 'XenDevice' object hierarchy
xen: introduce 'xen-block', 'xen-disk' and 'xen-cdrom
xen_be_init() function.
Subsequent patches will flesh-out the functionality of these objects.

cleaned up if QEMU terminates without devices being unrealized.
[1] The 'scanf' functions are actually not yet needed, but they will be
needed by code delivered in subsequent patches.

v5:
- Re-base
v3:
- Add missing return statement to xen_block_realize()
- Set device name to 'vbd' now the backend is functional
This is a purely cosmetic patch that purges remaining use of 'blk' and
'ioreq' in local function names, and then makes sure all functions are
prefixed with 'xen_block_'.
No functional change.

. These will
be modified by subsequent patches. A typedef for XenBlockDataPlane
has been added to the header (based on the old struct XenBlkDev name
for the moment) so that the old names don't need to leak out of the
dataplane code.

This is a purely cosmetic patch that substitutes the old 'struct XenBlkDev'
name with 'XenBlockDataPlane' and 'blkdev' field/variable names with
'dataplane', and then does necessary fix-up to adhere to coding style.
No functional change.

the new XenBlockDevice. This, like the driver layers, will be destroyed
after the XenBlockDevice is unrealized.
The legacy backend scan for 'qdisk' is removed by this patch, which makes
the 'xen_disk' code is redundant. The code will be removed by a subsequent
patch.
