[libvirt] [PATCH 00/25 v4] Support scsi device passthrough via scsi-generic

[Osier Yang]

This adds the support for qemu's scsi-generic device, which can be
used to passthrough scsi host device. An example of the XML:

  <hostdev mode='subsystem' type='scsi' managed='no'>
    <source>
      <adapter name='scsi_host7'/>
      <address bus='0' target='0' unit='0'/>
    </source>
    <address type='drive' controller='0' bus='0' target='0' unit='1'/>
  </hostdev>

v3 - v4 (details in each patch):
  * Rebased on top
  * Support <shareable>
  * Support <sgio>
  * Various preparation patches for <shareable> and <sgio>
  * Split 1/10 in v3 into 2 patches (<readonly> now is a single patch,
    for easy reviewing, and <readonly> is a sub-element of "hostdev"
    in rng schema, because it could be used by other type hostdev in
    future).
  * Split 4/10 in v3 into 2 patches (bootindex support now is a single
    patch, for easy reviewing)

v2.5 - v3 (details in each patch):
  * 1/10 and 2/10 of v2.5 are pushed
  * 8/10 of v2.5 is splitted
  * A better way to generate the address for scsi host device instead of
    the rigid one.
  * Support all scsi controllers when building the qemu command line.
  * Figure out the limits of the qemu properties, and do checking
  * Don't forget DAC and apparmor security backends
  * Orgnize the patches in a better way.
  * Fix the make check failure
