[PATCH v3 0/4] libbxl: add support for pvscsi, iteration 3

[Olaf Hering <olaf@aepfle.de>]

Port vscsi=[] and scsi-{attach,detach,list} commands from xend to libxl.

Changes between v2 and v3:
 - Adjust change for vscsiif.h
 - Support "naa.wwn:lun" notation in pvops kernel
 - Add example for pvops kernel using targetcli
   patch required for python-rtslib:
   http://article.gmane.org/gmane.linux.scsi.target.devel/8146
 - Use vdev variable in libxl_device_vscsi_parse

Initial attempt was sent a year ago:
http://lists.xenproject.org/archives/html/xen-devel/2014-04/msg03958.html
Most comments are addressed.

This version has been tested with SLES as backend and frontend.

Please review. The first two changes could be applied independent from
the libxl changes.
