Osier Yang c56fe7f1d6 qemu: Build command line for the new address format 
For any disk controller model which is not "lsilogic", the command
line will be like:

  -drive file=/dev/sda,if=none,id=drive-scsi0-0-3-0,format=raw \
  -device scsi-disk,bus=scsi0.0,channel=0,scsi-id=3,lun=0,i\
  drive=drive-scsi0-0-3-0,id=scsi0-0-3-0

The relationship between the libvirt address attrs and the qdev
properties are (controller model is not "lsilogic"; strings
inside <> represent libvirt adress attrs):
  bus=scsi<controller>.0
  channel=<bus>
  scsi-id=<target>
  lun=<unit>

* src/qemu/qemu_command.h: (New param "virDomainDefPtr def"
  for function qemuBuildDriveDevStr; new param "virDomainDefPtr
  vmdef" for function qemuAssignDeviceDiskAlias. Both for
  virDomainDiskFindControllerModel's use).

* src/qemu/qemu_command.c:
  - New param "virDomainDefPtr def" for qemuAssignDeviceDiskAliasCustom.
    For virDomainDiskFindControllerModel's use, if the disk bus is "scsi"
    and the controller model is not "lsilogic", "target" is one part of
    the alias name.
  - According change on qemuAssignDeviceDiskAlias and qemuBuildDriveDevStr

* src/qemu/qemu_hotplug.c:
  - Changes to be consistent with declarations of qemuAssignDeviceDiskAlias
    qemuBuildDriveDevStr, and qemuBuildControllerDevStr.

* tests/qemuxml2argvdata/qemuxml2argv-pseries-vio-user-assigned.args,
  tests/qemuxml2argvdata/qemuxml2argv-pseries-vio.args: Update the
  generated command line.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
